What is SSRI

SSRIs is short for selective serotonin reuptake inhibitors, which are a class of antidepressant medications that works by increasing serotonin levels in your brain, that are commonly prescribed to treat depression, anxiety disorders, obsessive-compulsive disorder (OCD), panic disorders, and eating disorder bulimia nervosa and other mental health conditions ¹, ². Selective serotonin reuptake inhibitors (SSRIs) work by blocking the reabsorption (reuptake) of serotonin, a neurotransmitter (a chemical messenger) in your brain, which increases the amount of serotonin available to nerve cells (neurons) in the brain which is associated with their antidepressant effect. Serotonin also known as 5-hydroxytryptamine or 5-HT, is one of the a biochemical messengers and regulators, synthesized from the essential amino acid L-Tryptophan that nerve cells (neurons) in your brain use to communicate ³, ⁴, ⁵. Raising serotonin levels can help regulate mood, appetite, digestion, sleep, and many other bodily functions. Selective serotonin reuptake inhibitors (SSRIs) include drugs such as citalopram, escitalopram, fluoxetine, paroxetine, and sertraline.

SSRIs drugs include:

• Citalopram (Celexa)
• Escitalopram (Lexapro)
• Fluoxetine (Prozac®, Prozac Weekly®, Rapuflux®, Selfemra®, and Sarafem®)
• Paroxetine (Paxil®, Aropax®, Brisdelle®, Pexeva® and Seroxat®)
• Sertraline (Zoloft)
• Vilazodone (Viibryd)

SSRIs common uses:

• Major depressive disorder
• Anxiety disorders, including generalized anxiety disorder (GAD) and panic disorder
• Severe phobias such as agoraphobia and social anxiety disorder (social phobia)
• Obsessive-compulsive disorder (OCD)
• Post-traumatic stress disorder (PTSD)
• Bulimia nervosa
• Bipolar depression ⁶

SSRIs can sometimes be used to treat other conditions, such as:

• Premenstrual syndrome (PMS)
• Fibromyalgia
• Irritable bowel syndrome (IBS)
• Headaches
• Neuropathic pain.

SSRIs are only available orally and come in multiple forms, including tablets, capsules, or liquid suspension/solution. There are currently no parenteral (IV, IM, SubQ), rectal, or other forms of SSRIs. SSRI administration is typically once-daily medication in the morning or nighttime. Except for vilazodone, SSRIs may be taken without regard to food. Take vilazodone with food ⁷.

SSRIs are usually taken in tablet form. When they’re prescribed, you’ll start on the lowest possible dose thought necessary to improve your symptoms. SSRIs usually need to be taken for 2 to 4 weeks before the benefit is felt. You may experience mild side effects early on, but it’s important that you don’t stop taking the medicine. These effects will usually wear off quickly.

If you take an SSRI for 4 to 6 weeks without feeling any benefit, speak to your doctor or mental health specialist. Your doctor or mental health specialist may recommend increasing your dose or trying an alternative antidepressant. This is because SSRIs differ in how well they block serotonin reuptake and in how quickly they break down and are cleared from the body.

An SSRI that is best for you depends on several factors, such as your symptoms and any other health conditions you may have.

A course of treatment usually continues for at least 6 months after you feel better, although longer courses are sometimes recommended and some people with recurrent problems may be advised to take them indefinitely.

SSRIs also need to be used with caution if you have certain underlying health problems, including diabetes, epilepsy and kidney disease.

Some SSRIs can react unpredictably with other medicines, including some over-the-counter painkillers and herbal remedies, such as St John’s wort. Always read the information leaflet that comes with your SSRI medicine to check if there are any medicines you need to avoid.

SSRIs are generally considered safe and effective, but they can cause side effects, including:

• Upset stomach, vomiting or diarrhea.
• Insomnia
• Headaches
• Sexual dysfunction
• Sweating
• Sleepiness or trouble sleeping.
• Dry mouth.
• Nervousness, anxiety or restlessness.
• Shakiness.
• Sexual problems, such as lessened sexual desire, trouble reaching orgasm or trouble getting and keeping an erection.
• Changes in appetite, leading to weight loss or weight gain.

Taking your SSRI with food may lessen the risk of an upset stomach. Also, so long as your SSRI medicien doesn’t keep you from sleeping, taking it at bedtime may lessen an upset stomach.

SSRIs are generally safe for most people. But some can cause safety issues. For example, citalopram can cause dangerous irregular heart rhythms if the dose is too high. The U.S. Food and Drug Administration (FDA) and the manufacturer recommend that the dose should be no more than 40 milligrams (mg) a day, but no more than 20 mg of citalopram a day for people over age 60.

Before you take an SSRI, talk with your doctor about:

• Interactions with other medicines and supplements. When taking an antidepressant, tell your doctor about any other prescription or nonprescription medicines, herbs, or other supplements you’re taking. Some antidepressants can interfere with the effectiveness of other medicines. Some antidepressants can cause dangerous reactions when combined with certain medicines or herbal supplements. For example, SSRIs may raise your risk of bleeding. The risk is higher when you also take other medicines that raise the risk of bleeding, for example, a nonsteroidal anti-inflammatory drug, such as aspirin or ibuprofen (Advil, Motrin IB, others), or warfarin (Jantoven) and other blood thinners.
• Serotonin syndrome. Rarely, an antidepressant can cause high levels of serotonin to build up in your body. Serotonin syndrome most often occurs when two medicines that raise the level of serotonin are combined. These include, for example, other antidepressants, some pain or headache medicines, and the herbal supplement St. John’s wort. Symptoms of serotonin syndrome include anxiety, being nervous or jittery, high fever, sweating, confusion, shaking, restlessness, lack of coordination, major changes in blood pressure, and a fast heartbeat. Get medical help right away if you have any of these symptoms.
• Antidepressants and pregnancy. Talk to your doctor about the risks and benefits of using specific antidepressants. Some antidepressants may harm your baby if you take them during pregnancy or while you’re breastfeeding. If you’re taking an antidepressant and you’re thinking about getting pregnant, talk with your doctor about the possible risks. Don’t stop taking your medicine without talking with your doctor first, as stopping puts you at risk.
• Suicide risk and antidepressants. Most antidepressants are generally safe. But the U.S. Food and Drug Administration (FDA) requires that all antidepressants carry boxed warnings, the strictest warnings for prescriptions. In some cases, children, teenagers and young adults under 25 may have an increase in suicidal thoughts or behavior when taking antidepressants. This may be more likely in the first few weeks after starting or when the dose is changed. Anyone taking an antidepressant should be watched closely for worsening depression or unusual behavior. If you or someone you know has suicidal thoughts when taking an antidepressant, call your doctor right away or get emergency help. Keep in mind that depression that’s not treated is a more concerning risk of suicide. And antidepressants may lessen suicide risk in the long run by improving mood for many people.
• Stopping treatment with SSRIs. SSRIs aren’t habit-forming. However, stopping antidepressant treatment suddenly or missing several doses can cause withdrawal-like symptoms. This is sometimes called discontinuation syndrome. Work with your doctor to slowly and safely lower your dose.
  • SSRI withdrawal-like symptoms can include:
    • Restlessness and anxiety.
    • Nausea.
    • Dizziness.
    • Feeling sluggish or sleepy.
    • Flu-like symptoms, such as chills, sweating and muscle aches.

Finding the right antidepressant

Different people may react differently to the same antidepressant. For example, one medicine may work better — or not as well — for you than for another person. Or you may have more, or fewer, side effects from taking a specific antidepressant than someone else does.

Traits passed down in your family play a role in how antidepressants affect you. If a relative responded well to a particular antidepressant, tell your doctor. This may be a good medicine for you to try first.

In some cases, results of special blood tests, where available, may offer clues about how your body may respond to a particular antidepressant. But other factors can affect your response to medicine. For example, people with a history of bipolar disorder typically aren’t given SSRIs for depression. That’s because SSRIs may worsen their symptoms.

When choosing an antidepressant, your doctor considers your symptoms, any health conditions you may have, other medicines you take and what has worked for you in the past.

It may take several weeks or more before an antidepressant is fully effective and for early side effects to ease up. Your doctor may recommend some dose changes or different antidepressants. With patience, you and your doctor can find a medicine that works well for you.

How selective serotonin reuptake inhibitor (SSRI) drugs work

The therapeutic actions of selective serotonin reuptake inhibitors (SSRIs) have their basis on increasing serotonin that researchers hypothesize as the cause of depression in the monoamine hypothesis ¹. Serotonin is a neurotransmitter (a messenger chemical that carries signals between nerve cells in the brain). It’s thought to have a good influence on mood, emotion and sleep. After carrying a message, serotonin is usually reabsorbed by the nerve cells (known as “reuptake”). Selective serotonin reuptake inhibitors (SSRIs) work by blocking (“inhibiting”) the reuptake of serotonin in the brain, thereby increasing serotonin activity, meaning more serotonin is available to pass further messages between nearby nerve cells. SSRIs inhibit the serotonin transporter (SERT) at the presynaptic axon terminal. By inhibiting serotonin transporter (SERT), an increased amount of serotonin (5-hydroxytryptamine or 5HT) remains in the synaptic cleft and can stimulate postsynaptic receptors for a more extended period ⁸, ⁹, ¹⁰, ⁷. However, it would be too simplistic to say that depression and related mental health conditions are caused by low serotonin levels, but a rise in serotonin levels can improve symptoms and make people more responsive to other types of treatment, such as Cognitive Behavioral Therapy (CBT).

Unlike other classes of antidepressants, SSRIs have little effect on other neurotransmitters, such as dopamine or norepinephrine. SSRIs also have relatively fewer side effects than tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs) due to fewer effects on adrenergic, cholinergic, and histaminergic receptors.

Selective serotonin reuptake inhibitor (SSRI) drugs uses

Selective serotonin reuptake inhibitors (SSRIs) are a widely used type of antidepressant (medicine used to treat clinical depression). SSRIs are usually the first choice medicine for depression because they generally have fewer side effects than most other types of antidepressant ¹. SSRIs are mainly prescribed to treat depression, particularly persistent or severe cases, and are often used in combination with a talking therapy such as cognitive behavioral therapy (CBT).

Selective serotonin reuptake inhibitors (SSRIs) are approved for use in both adult and children ¹¹, ¹²

SSRIs in use in the United States are:

• Fluoxetine
• Sertraline
• Paroxetine
• Fluvoxamine
• Citalopram
• Escitalopram
• Vilazodone

SSRIs currently with FDA labeled indications to treat the following conditions ¹:

• Major depressive disorder
• Generalized anxiety disorder (GAD)
• Bulimia nervosa
• Bipolar depression ⁶
• Obsessive-compulsive disorder (OCD)
• Panic disorder
• Premenstrual dysphoric disorder (PMDD)
• Treatment-resistant depression
• Post-traumatic stress disorder (PTSD)
• Social anxiety disorder (social phobia)
• Severe phobias such as agoraphobia

Other off-label uses of SSRI include but are not limited to ¹³, ¹:

• Binge eating disorder
• Body dysmorphic disorder
• Fibromyalgia
• Premature ejaculation
• Paraphilias: Paraphilia is an experience of recurring or intense sexual arousal to atypical objects, situations, fantasies, behaviors and/or targets (eg, children, corpses, animals) ¹⁴. Paraphilia has also been defined as a sexual interest in anything other than a legally consenting human partner. A total of eight Paraphilias are listed in the DSM V and include pedophilia, exhibitionism, voyeurism, sexual sadism, sexual masochism, frotteurism, fetishism, and transvestic fetishism ¹⁵. Although not innately pathological, a paraphilic disorder can evolve if paraphilia invokes harm, distress, or functional impairment on the lives of the affected individual or others.
  • Pedophilia is any sexual activity with a prepubescent child, where the offender/patient is at least sixteen years of age, and the victim is at least five years younger ¹⁶.
  • Exhibitionism is the exposure of an individual’s genitalia to unsuspecting strangers for sexual satisfaction ¹⁷
  • Voyeurism is the viewing of an unsuspecting person engaging in disrobing or sexual activity ¹⁸.
  • Sexual sadism is when sexual arousal is gained from inflicting mental or physical suffering on a nonconsenting person ¹⁹.
  • Sexual masochism is the derivation of sexual arousal from being the recipient of physical or mental abuse and/or humiliation ²⁰.
  • Frotteurism is the touching of or rubbing against a nonconsenting person ²¹.
  • Fetishism is the use of nonliving objects, most commonly shoes and undergarments, for sexual pleasure ²².
  • Transvestic fetishism is the derivation of sexual arousal from cross-dressing or dressing in clothes of the opposite sex ²³.
• Autism spectrum disorder (ASD) is a developmental disability that causes a complex range of behavioural symptoms.
• Raynaud phenomenon also called Raynaud’s disease is a condition that causes blood vessels in the extremities, particularly fingers and toes, to narrow in response to cold or stress, leading to reduced blood flow and a characteristic color change (white, then blue, then red)
• Vasomotor symptoms (hot flushes) associated with menopause.

SSRI Contraindications

SSRIs are contraindicated with the concurrent use of monoamine oxidase inhibitors (MAOIs), linezolid, and other medications that increase serotonin levels and could put patients at risk for life-threatening serotonin syndrome. Do not use SSRI if you have used an monoamine oxidase (MAO) inhibitor in the past 14 days. A dangerous drug interaction could occur. Monoamine oxidase (MAO) inhibitors include isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, rasagiline, phenelzine (Nardil), selegiline (Emsam, Zelapar), and tranylcypromine (Parnate). Wait at least 14 days after stopping an monoamine oxidase (MAO) inhibitor before you take SSRI.

Paroxetine is contraindicated in pregnancy and is classified as category D/X due to its teratogenic effects in causing cardiovascular defects, specifically heart malformations if prescribed in the first trimester ²⁴.

Pregnancy and SSRI

SSRIs can be prescribed if you’re pregnant, breastfeeding or under 18, but this depends if your doctor thinks that the benefits outweigh the risks. Talk to your doctor about what’s best for you or your child.

Babies of women who are taking an SSRI at the time of delivery may have some difficulties in the first few days of life. Reported symptoms include jitteriness, increased muscle tone, irritability, constant crying, changes in sleeping patterns, tremors, difficulty eating, and problems with breathing. Not every baby will experience these symptoms. For the SSRI medications, it is estimated that 10-30% of babies will be affected.

Some babies with symptoms of withdrawal may need to spend time in the neonatal intensive care unit (NICU) to receive additional care. However, in most cases the symptoms are mild and go away within two weeks. Reassuringly, there does not seem to be a dose-response relationship, which means that women who need a higher amount of medication to manage their anxiety are not expected to have babies who are at a higher risk for withdrawal.

SSRI side effects

Most people will only experience a few mild side effects when taking SSRIs. These can be troublesome at first, but they’ll generally improve with time ²⁵, ²⁶.

Common side effects of SSRIs can include ²⁷, ²⁸:

• feeling agitated, shaky or anxious
• diarrhea and feeling or being sick
• gastrointestinal distress
• dizziness
• blurred vision
• headache
• loss of libido (reduced sex drive)
• difficulty achieving orgasm during sex or masturbation
• in men, difficulty obtaining or maintaining an erection (erectile dysfunction)
• sleep disturbances
• weight changes
• xerostomia

SSRIs also have the potential to prolong the QT interval, which can lead to fatal arrhythmia, torsade de pointes. Citalopram has correlations with a longer QT duration, or QT prolongation than the other medications in this class ²⁹, ³⁰. Coagulopathy (bleeding disorder) also correlates with SSRI use ³¹. Although infrequent, as with all medications that increase serotonin activity, it is important to be aware of the risk of serotonin syndrome, particularly when prescribing multiple medications that may have serotonergic effects.

In 2004, the FDA issued a black box warning for SSRIs and other antidepressant medications due to a possible increased risk of suicidality among pediatric and young adult (up to age 25) populations ³², ³³. The risk and benefits of initiating SSRI therapy on acutely suicidal patients must be weighed, keeping in mind that depression itself is a large risk factor for the risk of suicide (usually indicated by suicidal ideation or intent) and requires treatment.

SSRIs are brokendown (metabolized) by and have effects on the cytochrome P450 system. Fluoxetine, paroxetine, sertraline, citalopram, and escitalopram are inhibitors of CYP2D6. Fluoxetine and fluvoxamine are inhibitors of CYP2C19. Fluvoxamine is an inhibitor of CYP1A2 ⁷.

You’ll usually need to see your doctor every few weeks when you first start taking SSRIs to discuss how well the medicine is working. You can also contact your doctor at any point if you experience any troublesome or persistent side effects.

SSRI Overdose

Symptoms of SSRI (selective serotonin reuptake inhibitors) overdose may include the following:

• dizziness
• drowsiness
• sweating
• agitation, hallucinations, fever, sweating, confusion, fast heartbeat, shivering, severe muscle stiffness or twitching, loss of coordination, nausea, vomiting, or diarrhea
• nausea
• vomiting
• uncontrollable shaking of a part of the body
• drowsiness
• fast, irregular, or pounding heartbeat
• memory loss
• confusion
• seizures
• coma (loss of consciousness)
• fast breathing
• bluish color around mouth, fingers, or fingernails
• muscle pain
• dark-colored urine.

Out of all the SSRIs, citalopram and escitalopram are more likely to cause overdose due to differences in their structures. Citalopram and escitalopram have an increased risk of heart toxicity due to QT prolongation, which can progress to serious arrhythmias such as Torsades de pointes, a type of very fast heart rhythm (tachycardia) that starts in your heart’s lower chambers (ventricles).

Serotonin syndrome

Serotonin syndrome also called serotonin toxicity is a potentially life threatening condition due to excessive serotonin in your body ³⁴, ³⁵. Serotonin syndrome most often occurs when two medicines that affect the body’s level of serotonin are taken together at the same time. The medicines cause too much serotonin to be released or to remain in the brain area. Serotonin syndrome (serotonin toxicity) can occur when you increase the dose of such a drug or add a new drug to your regimen. Certain illegal drugs and dietary supplements also are associated with serotonin syndrome. For example, you can develop serotonin syndrome if you take migraine medicines called triptans together with antidepressants called selective serotonin reuptake inhibitors (SSRIs), and selective serotonin/norepinephrine reuptake inhibitors (SSNRIs).

Serotonin syndrome symptoms and their severity vary from person to person. They can be mild to severe to even fatal.

If you’re taking a medication that affects serotonin and experience any of the following symptoms, call your doctor or visit an urgent or emergency care facility right away.

Mild symptoms

• Nervousness.
• Nausea, vomiting.
• Diarrhea.
• Dilated pupils.
• Tremor.

Moderate symptoms

• Agitation, restlessness.
• Muscle twitching, involuntary muscle contractions, muscle spasms, muscle rigidity.
• Sweating, shivering.
• Abnormal (side-to-side) eye movements.

Severe symptoms

• Confusion, disorientation, delirium.
• Rapid heart rate.
• High blood pressure.
• High body temperature (greater than 101.3° Fahrenheit [38.5° Celsius]).
• Seizures.
• Abnormal heartbeat.
• Passing out, fainting.

Symptoms usually begin within a few hours of taking a new medication that affects serotonin levels or increasing the dose of a drug you’re already taking. Nearly all people will experience symptoms within 24 hours of starting, adding or increasing the dosage of a serotonergic medication or product.

Serotonin syndrome generally doesn’t cause any problems once serotonin levels are back to their original levels.

Without treatment, serotonin symptoms can cause:

• Seizures.
• Trouble breathing.
• Kidney failure. The breakdown products of muscle (from spasms) are released into your blood, which is filtered through your kidneys. If left untreated, these products can cause severe kidney damage.
• Coma.
• Death.

If left untreated, severe serotonin syndrome can lead to unconsciousness and death.

There aren’t any tests to diagnose serotonin syndrome symptoms. Your doctor usually makes the diagnosis based on the results of your physical exam, review of your symptoms and history of medications you take that affect serotonin levels.

You can assist your doctor by telling them all the products you take, including prescription medicines, over-the-counter medicines, supplements, herbal products and illegal drugs. Be honest. Don’t worry. Your doctor is here to help you, not judge you.

To make sure your symptoms are caused by serotonin syndrome and not due to another cause, your doctor may use tests to:

• Measure levels of any drugs you’re using
• Check for signs of infection
• Check body functions that may be affected by serotonin syndrome

A number of conditions can cause symptoms similar to those of serotonin syndrome. Minor symptoms can be caused by several conditions. Moderate and severe symptoms similar to those of serotonin syndrome could be caused by:

• A serious reaction to certain medications, such as some anesthetics, antipsychotic drugs and other agents known to produce these severe reactions
• An overdose of illicit drugs, antidepressant medications or other medications that increase serotonin levels
• Damage associated with illicit drug use
• Severe alcohol withdrawal

Your doctor may order additional tests to rule out other causes of your symptoms. Tests may include:

• Blood and urine tests
• Chest X-ray
• Computerized Tomography (CT) scan
• Spinal tap (lumbar puncture)

Treatment of serotonin syndrome depends on the severity of your symptoms.

• If your symptoms are minor, a visit to the doctor and stopping the medication causing the problem may be enough.
• If you have symptoms that concern your doctor, you may need to go to the hospital. Your doctor may have you stay in the hospital for several hours to make sure your symptoms are improving.
• If you have severe serotonin syndrome, you’ll need intensive treatment in a hospital.

Depending on your symptoms, you may receive the following treatments:

• Muscle relaxants. Benzodiazepines, such as diazepam (Valium, Diastat) or lorazepam (Ativan), can help control agitation, seizures and muscle stiffness.
• Serotonin antagonists. If other treatments aren’t working, serotonin antagonists such as the medicine cyproheptadine may help. These medicines work by blocking certain serotonin receptors, lessening the activity that causes the symptoms.
• Oxygen and intravenous (IV) fluids. Breathing oxygen through a mask helps maintain oxygen levels in your blood, and IV fluids are used to treat dehydration and fever.
• Drugs that control heart rate and blood pressure. These may include esmolol (Brevibloc) or nitroprusside (Nitropress) to reduce a high heart rate or high blood pressure. If your blood pressure is too low, your doctor may give you phenylephrine (Vazculep) or epinephrine (Adrenalin, Epipen, others).
• A breathing tube and machine and medication to paralyze your muscles. You may need this treatment if you have a high fever (106° Fahrenheit [41.1° Celsius]).

Milder forms of serotonin syndrome usually go away within 24 to 72 hours of stopping medications that increase serotonin. You may need to take medications to block the effects of serotonin already in your system.

However, symptoms of serotonin syndrome caused by some antidepressants could take several weeks to go away completely. These medications remain in your system longer than do other medications that can cause serotonin syndrome.

List of selective serotonin reuptake inhibitors (SSRIs)

Common selective serotonin reuptake inhibitors (SSRIs) include:

• Citalopram (Celexa)
• Escitalopram (Lexapro)
• Fluoxetine (Prozac®, Prozac Weekly®, Rapuflux®, Selfemra®, and Sarafem®)
• Paroxetine (Paxil®, Aropax®, Brisdelle®, Pexeva® and Seroxat®)
• Sertraline (Zoloft)
• Vilazodone (Viibryd)

Citalopram

Citalopram belongs to the class of antidepressants known as selective serotonin reuptake inhibitors (SSRIs) ³⁶, ³⁷, ³⁸. Citalopram works by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance. Citalopram is a medication that has been used to treat depression, including major depressive disorder. Citalopram is also sometimes used to treat obsessive-compulsive disorder [OCD] (with bothersome thoughts that won’t go away and the need to perform certain actions over and over), eating disorders, alcoholism, panic disorder (condition that causes sudden attacks of extreme fear with no apparent cause), premenstrual dysphoric disorder [PMDD] (a group of physical and emotional symptoms that occur before the menstrual period each month), social anxiety disorder (extreme fear of interacting with others or performing in front of others that interferes with normal life), post traumatic stress disorder (PTSD), tingling in the hands and feet caused by diabetes nerve damage (diabetic neuropathy), and certain male sexual problems. Citalopram may be prescribed for other uses; ask your doctor for more information.

Citalopram was approved for use in the United States in 1998 and Citalopram has become one of the most widely used antidepressant medications, with more than 16 million prescriptions being written yearly ³⁸.

Citalopram is available as tablets of 10, 20 and 40 mg and in an oral solution (liquid) of 10 mg/5 mL in several generic forms and under the brand name of Celexa. Citalopram is usually taken once a day, in the morning or in the evening, with or without food. The recommended dosage of citalopram in adults is 20 mg once daily, increasing to 40 mg daily if necessary. Take citalopram at around the same time every day. Your doctor may start you on a low dose of citalopram and gradually increase your dose, not more often than once a week. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take citalopram exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may order certain laboratory tests and electrocardiograms (ECG; a test to monitor your heart rate and rhythm) before you start taking citalopram and during your treatment with citalopram.

It may take 1 to 4 weeks before you notice the full benefit of citalopram. Continue to take citalopram even if you feel well. Do not stop taking citalopram without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking citalopram, you may experience withdrawal symptoms such as mood changes, irritability, agitation, dizziness, numbness, tingling or electric shock-like sensations in the hands or feet, anxiety, confusion, headache, tiredness, nausea, sweating, shaking, frenzied or abnormally excited mood, and difficulty falling asleep or staying asleep. Tell your doctor if you experience any of these symptoms while you are decreasing your dose of citalopram or soon after you stop taking citalopram.

Common side effects of Citalopram are drowsiness, dyspepsia, nausea, headache, increased sweating and sexual dysfunction. Rare, but potentially severe adverse events include suicidal ideation and behavior, prolongation of the QTc interval, serotonin syndrome, precipitation of acute mania and acute glaucoma.

Before taking Citalopram

You should not use Citalopram if you are allergic to citalopram or escitalopram (Lexapro), or if you also take pimozide. Do not take pimozide (Orap) while you are taking Citalopram. Using these medicines together can cause very serious heart problems.

You should know that citalopram is very similar to another SSRI, escitalopram (Lexapro). You should not take these two medications together.

Do not use citalopram if you have used an monoamine oxidase (MAO) inhibitor in the past 14 days. A dangerous drug interaction could occur. Monoamine oxidase (MAO) inhibitors include isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, rasagiline, phenelzine (Nardil), selegiline (Emsam, Zelapar), and tranylcypromine (Parnate). Wait at least 14 days after stopping an monoamine oxidase (MAO) inhibitor before you take citalopram.

Tell your doctor if you also use stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson’s disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with citalopram could cause a serious condition called serotonin syndrome.

To make sure citalopram is safe for you, tell your doctor if you have ever had:

• heart problems, high blood pressure, long QT syndrome (a rare heart problem that may cause irregular heartbeat, fainting, or sudden death),
• a heart attack, or if you have or have ever had a slow or irregular heartbeat, heart failure (condition in which the heart cannot pump enough blood to other parts of the body) or other heart conditions.
• a stroke
• bleeding problems
• sexual problems
• narrow-angle glaucoma. You should know that citalopram may cause angle-closure glaucoma, a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision. Talk to your doctor about having an eye examination before you start taking this medication. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, call your doctor or get emergency medical treatment right away.
• seizures or epilepsy
• bipolar disorder (manic depression) in you or a family member
• an electrolyte imbalance such as low levels of potassium, magnesium, or sodium in your blood.
• liver or kidney disease.

The following nonprescription or herbal products may interact with citalopram: St. John’s wort; tryptophan; cimetidine (Tagamet); aspirin and nonsteroidal anti-inflammatory drugs (NSAIDS) such as ibuprofen (Advil, Motrin, others) and naproxen (Aleve). Be sure to let your doctor and pharmacist know that you are taking these medications before you start taking citalopram. Do not start any of these medications while taking citalopram without discussing with your doctor.

People with depression or mental illness may have thoughts about suicide. Some young people may have increased suicidal thoughts when first starting a medicine to treat depression. Stay alert to changes in your mood or symptoms. Your family or caregivers should also watch for sudden changes in your behavior.

Tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breast-feeding. Taking citalopram during the last 3 months of pregnancy may harm the unborn baby, but stopping the medicine may not be safe for you. Citalopram may cause problems in newborns following delivery if it is taken during the last months of pregnancy. Do not start or stop citalopram without asking your doctor.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of citalopram on the baby.

Ask a doctor if it is safe to breastfeed while using Citalopram.

You should know that citalopram may make you drowsy and may affect your judgment, thinking, and movements. Do not drive a car or operate machinery until you know how Citalopram affects you. Alcohol can make the side effects of citalopram worse.

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to Citalopram or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children

Appropriate studies have not been performed on the relationship of age to the effects of citalopram in the pediatric population. Safety and efficacy have not been established.

Elderly

Citalopram capsules is not recommended for use in the elderly because an adjustment in the dose is not possible with the available dose strength of Citalopram.

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of citalopram in the elderly. However, elderly patients are more likely to have hyponatremia (low sodium in the blood), which may require caution and an adjustment in the dose for patients receiving citalopram.

Pregnancy

It is not known if citalopram can make it harder for a woman to get pregnant ³⁹. Studies in animals found that citalopram might cause some reduced fertility (ability to get pregnant) ³⁹.

Miscarriage is common and can occur in any pregnancy for many different reasons. There have been some studies that suggested taking antidepressant medications might slightly increase the chance of miscarriage. However, a study on citalopram and escitalopram did not find an increased chance of miscarriage in women taking these medications ³⁹.

Every pregnancy starts out with a 3-5% chance of having a birth defect. This is called the background risk. There are reports of more than 15,000 pregnancies exposed to citalopram or escitalopram. Overall, the available data do not suggest that citalopram or escitalopram increases the chance of birth defects. While some reports have suggested an increased chance of heart defects or other birth defects, most studies have not found an increased chance of birth defects ³⁹.

Some studies suggest that taking citalopram or escitalopram throughout the pregnancy might increase the chance of pregnancy-related problems such as preterm birth (birth before 37 weeks of pregnancy) and low birth weight (weighing less than 5 pounds, 8 ounces [2500 grams] at birth). However, research has also shown that when depression is left untreated during pregnancy, there could be an increased chance of pregnancy complications. This makes it hard to know if it is the medication, untreated depression, or other factors that are increasing the chance for these problems.

Some, but not all, studies have suggested that when pregnant women take SSRIs such as escitalopram or citalopram during the second half of the pregnancy, their babies might have an higher chance for a serious lung condition called persistent pulmonary hypertension. Persistent pulmonary hypertension happens in 1 or 2 out of 1,000 births. Among the studies looking at this, the overall chance for pulmonary hypertension when an SSRI was used in pregnancy was less than 1/100 (less than 1%).

One small study followed eleven babies exposed to citalopram during pregnancy. At one year of age there was no difference in their development compared to children who were not exposed to citalopram. Most studies find no increase in attention deficit hyperactivity disorder (ADHD) in children exposed to SSRIs during pregnancy. Most studies also find that SSRIs do not appear to increase the chance of autism spectrum disorder (ASD) after considering the effects of maternal depression or other factors.

Some medications taken during pregnancy are associated with withdrawal symptoms in a newborn after delivery. If you are taking escitalopram or citalopram at the time of delivery, your baby might have irritability, jitteriness, tremors (shivering), constant crying, different sleep patterns, problems with eating and controlling body temperature, and some problems with breathing. In most cases, these symptoms are mild and go away within a couple weeks with no treatment. Some babies may need to stay in the nursery or neonatal intensive care unit (NICU) until the symptoms go away. Most babies exposed to escitalopram or citalopram in late pregnancy do not have these symptoms. It is important that your doctor know you are taking these medications so that if symptoms occur your baby can get the care that is best for them.

Breastfeeding

Several studies have shown that small amounts of citalopram are found in breast milk ³⁹. There have been a few case reports of sleepiness and weight loss, but in most studies no harmful effects were seen in breastfed babies ³⁹. Studies also showed no difference in the intellectual development of babies exposed to citalopram during breastfeeding. A nursing infant should be monitored for being very sleepy (hard to wake for feeds), poor feeding and poor weight gain, especially in younger, exclusively breastfed infants and when a combination of medications for mental health are used. Be sure to talk to your doctor about all your breastfeeding questions. An alternative to Citalopram should be prescribed or you should stop breastfeeding while using citalopram.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking Citalopram, it is especially important that your doctor know if you are taking any of the medicines listed below.

Citalopram Dosage

The dose of Citalopram will be different for different patients. Follow your doctor’s orders or the directions on the label. The following information includes only the average doses of Citalopram. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

For oral dosage forms (capsules)

• For depression
  • Adults: 30 milligrams (mg) once a day. Your doctor may adjust your dose as needed. Do not start treatment with citalopram capsules because the only available dose strength is 30 mg. Use another dosage form of citalopram (eg, solution or tablets) for starting treatment and adjusting doses other than 30 mg once a day.
  • Older adults: Use is not recommended.
  • Children: Use and dose must be determined by your doctor.

For oral dosage forms (solution or tablets)

• For depression
  • Adults: At first, 20 milligrams (mg) once a day, taken either in the morning or evening. Your doctor may adjust your dose as needed. However, the dose is usually not more than 40 mg per day.
  • Older adults: 20 mg once a day, taken either in the morning or evening.
  • Children: Use and dose must be determined by your doctor.

Missed Dose

If you miss a dose of Citalopram, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Citalopram may decrease appetite and cause weight loss in children. Your child’s doctor will watch his or her growth carefully. Talk to your child’s doctor if you have concerns about your child’s growth or weight while he or she is taking this medication. Talk to your child’s doctor about the risks of giving citalopram to your child.

Citalopram may cause other side effects. Call your doctor if you have any unusual problems while taking citalopram.

Escitalopram

Escitalopram belongs to the class of antidepressants known as selective serotonin reuptake inhibitors (SSRIs) ⁴⁰. Escitalopram contains the same active medication as citalopram. These two drugs act in a very similar way by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance. Escitalopram has been used to treat depression in adults and children and teenagers 12 years of ago or older. Escitalopram is also used to treat generalized anxiety disorder (GAD, excessive worry and tension that disrupts daily life and lasts for 6 months or longer) in adults, teenagers, and children 7 years of age and older.

Escitalopram was approved for use in the United States in 2002 and is available in tablets of 5, 10, and 20 mg and a solution (liquid) under the brand name Lexapro. It is usually taken once a day with or without food. The recommended dosage of escitalopram is 10 mg once daily, increasing to 20 mg daily if necessary. To help you remember to take escitalopram, take it at around the same time every day, in the morning or in the evening. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take escitalopram exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may start you on a low dose of escitalopram and increase your dose after 1 week in adults and after 2 or 3 weeks in teenagers and children 7 years of age and older.

It may take 1 to 4 weeks or longer before you feel the full benefit of escitalopram. Continue to take escitalopram even if you feel well. Do not stop taking escitalopram without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking escitalopram, you may experience withdrawal symptoms such as mood changes, irritability, agitation, nausea, dizziness, burning, numbness, or tingling in the hands or feet, anxiety, confusion, headache, sweating, shaking, frenzied or abnormally excited mood, tiredness, and difficulty falling asleep or staying asleep. Tell your doctor if you experience any of these symptoms while you are decreasing your dose of escitalopram or soon after you stop taking escitalopram.

Before taking Escitalopram

You should not use escitalopram if you are allergic to escitalopram or citalopram (Celexa), or if you also take pimozide.

Do not use escitalopram within 14 days before or 14 days after you have used an monoamine oxidase (MAO) inhibitor. A dangerous drug interaction could occur. Monoamine oxidase (MAO) inhibitors include isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, rasagiline, phenelzine (Nardil), selegiline (Emsam, Zelapar), and tranylcypromine (Parnate). You must wait at least 14 days after stopping an monoamine oxidase (MAO) inhibitor before you take escitalopram.

You should know that escitalopram is very similar to another SSRI, citalopram (Celexa). You should not take these two medications together.

Some young people have thoughts about suicide when first taking an antidepressant. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

To make sure escitalopram is safe for you, tell your doctor if you have ever had:

• Bipolar disorder (mood disorder with mania and depression)
• Bleeding problems
• Drug addiction
• Angle-closure glaucoma  (a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision). Talk to your doctor about having an eye examination before you start taking this medication. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, call your doctor or get emergency medical treatment right away.
• Hyponatremia (low sodium in the blood)
• Heart disease or heart attack
• High blood pressure
• Kidney disease
• Liver disease—Use with caution. The effects may be increased because of slower removal of the medicine from the body.
• Mania
• Seizures
• Sexual problems—Use with caution. May make these conditions worse.
• Stroke
• Suicidal thoughts.

Some medications should not be taken with escitalopram. Other medications may cause dosing changes or extra monitoring when taken with escitalopram. Make sure you have discussed any medications you are currently taking or plan to take before starting escitalopram with your doctor and pharmacist. Before starting, stopping, or changing any medications while taking escitalopram, please get the advice from your doctor or pharmacist.

The following nonprescription or herbal products may interact with escitalopram: aspirin, ibuprofen (Advil, Motrin IB), naproxen (Aleve), St. John’s wort, or tryptophan. Be sure to let your doctor and pharmacist know that you are taking these medications before you start taking escitalopram. Do not start any of these medications while taking escitalopram without discussing with your doctor.

Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson’s disease, migraine headaches, serious infections, or prevention of nausea and vomiting. These medicines may interact with escitalopram and cause a serious condition called serotonin syndrome.

You should know that escitalopram may make you drowsy and may affect your judgment, thinking, and movements. Do not drive a car or operate machinery until you know how escitalopram affects you. Remember that alcohol can add to the drowsiness caused by escitalopram.

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to Escitalopram or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of escitalopram in children 12 years of age and older with depression. However, safety and efficacy have not been established in children less than 12 years of age. Escitalopram may cause weight loss or a decrease in appetite. Teenagers who will be taking it for a long time should have their weight and growth measured on a regular basis.

Appropriate studies have not been performed on the relationship of age to the effects of escitalopram in children younger than 7 years of age with generalized anxiety disorder. Safety and efficacy have not been established.

Elderly

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of escitalopram in the elderly. However, elderly patients are more likely to have hyponatremia (low sodium in the blood) and age-related liver problems, which may require caution and an adjustment in the dose for patients receiving escitalopram.

Pregnancy

It is not known if escitalopram can make it harder for a woman to get pregnant ³⁹. Studies in animals found that escitalopram might cause some reduced fertility (ability to get pregnant) ³⁹.

Miscarriage is common and can occur in any pregnancy for many different reasons. There have been some studies that suggested taking antidepressant medications might slightly increase the chance of miscarriage. However, a study on citalopram and escitalopram did not find an increased chance of miscarriage in women taking these medications ³⁹.

Every pregnancy starts out with a 3-5% chance of having a birth defect. This is called the background risk. There are reports of more than 15,000 pregnancies exposed to citalopram or escitalopram. Overall, the available data do not suggest that citalopram or escitalopram increases the chance of birth defects. While some reports have suggested an increased chance of heart defects or other birth defects, most studies have not found an increased chance of birth defects ³⁹.

Some studies suggest that taking citalopram or escitalopram throughout the pregnancy might increase the chance of pregnancy-related problems such as preterm birth (birth before 37 weeks of pregnancy) and low birth weight (weighing less than 5 pounds, 8 ounces [2500 grams] at birth). However, research has also shown that when depression is left untreated during pregnancy, there could be an increased chance of pregnancy complications. This makes it hard to know if it is the medication, untreated depression, or other factors that are increasing the chance for these problems.

Fluoxetine

Fluoxetine belongs to the class of antidepressants known as selective serotonin reuptake inhibitors (SSRIs) ⁴¹, ⁴². Fluoxetine works by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance. Fluoxetine is a medication that has been used to treat depression, obsessive-compulsive disorder (OCD, bothersome thoughts that won’t go away and the need to perform certain actions over and over), Tourette’s syndrome, bulimia nervosa, panic disorder (a type of anxiety disorder characterized by recurring, unexpected panic attacks, which are sudden episodes of intense fear or discomfort, often accompanied by physical symptoms, and persistent worry about future attacks), and premenstrual dysphoric disorder [PMDD] symptoms (a more severe form of premenstrual syndrome [PMS] characterized by extreme mood swings, bloating, irritability, breast tenderness and depression, occurring in the week or two before menstruation). Fluoxetine has also been used to treat body dysmorphic disorder, borderline personality disorder, hot flushes of menopause, post traumatic stress disorder (PTSD), alcoholism, attention-deficit/hyperactivity disorder (ADHD), sleep disorders, headaches, mental illness, sexual problems, phobias and Raynaud’s phenomenon. Fluoxetine is also used along with olanzapine (Zyprexa) to treat depression that did not respond to other medications and episodes of depression in people with bipolar disorder type 1 (manic-depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods). Fluoxetine may be prescribed for other uses; ask your doctor for more information.

Fluoxetine was approved for use in the United States in 1987 and it became one of the most widely used antidepressant medications, more than 20 million prescriptions being written yearly ⁴¹.

Fluoxetine is available as tablets, delayed-release (releases the medication in the intestine) capsules of 10, 20 and 40 mg and in an oral solution (liquid) of 20 mg/5 mL, in multiple generic forms and under the brand names of Prozac and Sarafem. Fixed combinations of fluoxetine with olanzapine (Symbyax and generic forms) are also available. A long acting formulation of 90 mg of fluoxetine has been developed for once weekly dosing (Prozac weekly).

Fluoxetine may be taken with or without food. Fluoxetine capsules, tablets, and liquid are usually taken once a day in the morning or twice a day in the morning and at noon. The recommended dosage of standard formulations of fluoxetine in adults is 20 mg once daily, increasing to 40 mg daily if necessary and not exceeding 80 mg daily.

Fluoxetine delayed-released capsules are usually taken once a week. Take fluoxetine at around the same time(s) every day. Swallow the delayed-release capsules whole; do not cut, crush, or chew them. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fluoxetine exactly as directed. Your doctor may start you on a low dose of fluoxetine and gradually increase your dose. Do not take more or less of it or take it more often than prescribed by your doctor.

It may take 4 to 5 weeks or longer before you feel the full benefit of fluoxetine. Continue to take fluoxetine even if you feel well. Do not stop taking fluoxetine without talking to your doctor. If you suddenly stop taking fluoxetine, you may experience withdrawal symptoms such as mood changes, irritability, agitation, dizziness, numbness or tingling in the hands or feet, anxiety, sweating, confusion, headache, tiredness, and difficulty falling asleep or staying asleep. Your doctor will probably decrease your dose gradually.

Common side effects of fluoxetine are drowsiness, dyspepsia, nausea, headache, increased sweating, increased appetite, weight gain and sexual dysfunction.

Before taking Fluoxetine

You should not use Fluoxetine if you are allergic to fluoxetine, if you also take pimozide or thioridazine. Tell your doctor and pharmacist if you are allergic to fluoxetine, any other medications, or any of the ingredients in fluoxetine capsules, tablets, or solution. Ask your pharmacist for a list of the ingredients.

Do not use fluoxetine if you have used an monoamine oxidase (MAO) inhibitor in the past 14 days. A dangerous drug interaction could occur. Monoamine oxidase (MAO) inhibitors include isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, rasagiline, phenelzine (Nardil), selegiline (Emsam, Zelapar), and tranylcypromine (Parnate). You must wait at least 14 days after stopping an monoamine oxidase (MAO) inhibitor before you take fluoxetine. You must wait 5 weeks after stopping fluoxetine before you can take thioridazine or an monoamine oxidase (MAO) inhibitor.

Tell your doctor about all other antidepressants you take, especially Celexa, Cymbalta, Desyrel, Effexor, Lexapro, Luvox, Oleptro, Paxil, Pexeva, Symbyax, Viibryd, or Zoloft.

To make sure fluoxetine is safe for you, tell your doctor if you have ever had:

• Bipolar disorder (mood disorder with mania and depression)
• Bleeding problems
• Diabetes
• Drug abuse
• Angle-closure glaucoma. You should know that fluoxetine may cause angle-closure glaucoma, a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision. Talk to your doctor about having an eye examination before you start taking fluoxetine. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, see your doctor or get emergency medical treatment right away.
• Hyponatremia (low sodium in the blood)
• Mania
• Seizures or epilepsy
• Sexual problems—Use with caution. May make these conditions worse.
• Heart attack or stroke
• Heart failure
• Heart rhythm problems such as prolonged QT interval (a rare heart problem that may cause irregular heartbeat, fainting, or sudden death)
• Cirrhosis of the liver or liver disease—Use with caution. The effects may be increased because of slower removal of the medicine from the body.
• Urination problems
• Suicidal thoughts
• Electroconvulsive therapy (ECT), procedure in which small electric shocks are administered to the brain to treat certain mental illnesses.
• Hypokalemia (low potassium in the blood) or
• Hypomagnesemia (low magnesium in the blood)—May cause side effects to become worse.

Also tell your doctor if you have a low level of potassium, magnesium, or sodium in your blood.

Tell your doctor if you have recently had a heart attack and if you have or have ever had a slow or irregular heartbeat, heart failure, or any other heart problems; high blood pressure; bleeding problems; a stroke; liver or kidney disease.

The following nonprescription or herbal products may interact with fluoxetine: St. John’s wort; tryptophan. Be sure to let your doctor and pharmacist know that you are taking these medications before you start taking fluoxetine. Do not start any of these medications while taking fluoxetine without discussing with your doctor.

Some young people have thoughts about suicide when first taking an antidepressant. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.

Older adults may be more sensitive to the effects of fluoxetine.

Ask your doctor about taking fluoxetine if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breastfeeding. Taking an SSRI antidepressant during late pregnancy may cause serious medical complications in the baby if it is taken during the last months of pregnancy. However, you may have a relapse of depression if you stop taking your antidepressant. Tell your doctor right away if you become pregnant. If you are pregnant, your name may be listed on a pregnancy registry to track the effects of fluoxetine on the baby.

If you are breastfeeding, tell your doctor if you notice agitation, fussiness, feeding problems, or poor weight gain in the nursing baby.

You should know that fluoxetine may make you drowsy and may affect your judgment, thinking, and movements. Do not drive a car or operate machinery until you know how fluoxetine affects you. Remember that alcohol can add to the drowsiness caused by fluoxetine.

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to Fluoxetine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of fluoxetine in children. However, safety and efficacy have not been established to treat depression in children younger than 8 years of age, to treat obsessive-compulsive disorder in children younger than 7 years of age, and to treat depression that is part of bipolar disorder in children younger than 10 years of age.

Appropriate studies have not been performed on the relationship of age to the effects of fluoxetine in children with bulimia nervosa, panic disorder, or treatment resistant depression. Safety and efficacy have not been established.

Elderly

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of fluoxetine in the elderly. However, elderly patients are more likely to have hyponatremia (low sodium in the blood) than younger adults, which may require caution and an adjustment in the dose for patients receiving fluoxetine.

Pregnancy

Fluoxetine has been studied in women having medical treatments because they were already having a hard time getting pregnant. In these studies, those who took fluoxetine got pregnant at the same rate as those who did not take fluoxetine ⁴³.

Out of all babies born each year, about 3 out of 100 (3%) will have a birth defect. Doctors look at research studies to try to understand if an exposure, like fluoxetine, might increase the chance of birth defects in a pregnancy. Fluoxetine use is not expected to increase the chance of birth defects. There are reports of over 10,000 pregnancies exposed to fluoxetine in the first trimester (when many major birth defects can happen). No pattern of birth defects has been found and most studies have not found an increased chance of birth defects related to fluoxetine use.

Some studies have suggested an increased chance of heart defects or other birth defects. However, there is no proven increased chance of birth defects directly related to fluoxetine.

Some studies suggest a higher chance of preterm delivery (birth before week 37) or low birth weight (weighing less than 5 pounds, 8 ounces [2500 grams] at birth) with the use of fluoxetine in pregnancy. However, research has also shown that when conditions such as depression or anxiety are untreated or undertreated during pregnancy, there could be an increased chance of pregnancy complications. This makes it hard to know if it is the medication, the underlying condition, or other factors that might increase the chance for these problems.

Some, but not all, studies have suggested that when women who are pregnant take SSRIs during the second half of pregnancy, their babies might have an increased chance for a serious lung condition called persistent pulmonary hypertension (PPH). Persistent pulmonary hypertension happens in 1 or 2 out of 1,000 births. A recent report that combined results from several studies suggested the chance for persistent pulmonary hypertension might be increased if an SSRI was used during pregnancy. However, it was not clear if this was due to medication exposure or to other exposures that people who take SSRIs have in common, such as higher rates of smoking. Data from studies suggest the overall chance for persistent pulmonary hypertension when an SSRI is used in pregnancy is less than 1/100 (less than 1%).

The use of fluoxetine during pregnancy and/or in the third trimester can cause temporary symptoms in newborns soon after birth. These symptoms are sometimes referred to as withdrawal. Symptoms include being irritable and/or jittery, crying, tight muscles, trouble breathing, unusual sleep patterns, tremors (shivers), and/or trouble eating. In most cases symptoms are mild and go away in a few weeks with no treatment, or with only supportive care. Not all babies exposed to fluoxetine will have these symptoms. There might be a higher chance for withdrawal symptoms if other psychiatric medications are also taken with fluoxetine during pregnancy. It is important that your doctor know you are taking fluoxetine so that if symptoms occur your baby can get the care that is best for them.

Does taking fluoxetine in pregnancy affect future behavior or learning for the child?

A few studies have looked at the development of children from age 16 months to 7 years and did not find differences between children who were exposed to fluoxetine during pregnancy and those who were not. Most studies found no increase in attention deficit hyperactivity disorder (ADHD) in children exposed to SSRIs like fluoxetine during pregnancy. Most studies also find that SSRIs like fluoxetine do not appear to increase the chance of autism spectrum disorders (ASD) after adjusting for factors such as maternal illness.

Breastfeeding

Fluoxetine gets into breast milk and most reports find no side effects in breastfed babies ⁴³. In a small number of cases, irritability, vomiting, diarrhea, and less sleep have been reported. One study noted slightly less weight gain in infants exposed to fluoxetine via breast milk; however, this would likely only be an issue if the infant’s weight gain was already a concern ⁴³. One study showed that mental and physical development was normal for infants exposed to fluoxetine in breast milk in their first year of life ⁴³. Studies in women breastfeeding have demonstrated harmful infant effects ⁴⁴. If you suspect the baby has any symptoms (such as irritability, vomiting, diarrhea, trouble sleeping, or trouble gaining weight) contact the child’s doctor.

The product label for fluoxetine recommends women who are breastfeeding not use this medication. But the benefit of treating your condition might outweigh possible risks. Your doctor can talk with you about using fluoxetine and what treatment is best for you. Be sure to talk to your doctor about all your breastfeeding questions.

An alternative to Fluoxetine should be prescribed or you should stop breastfeeding while using Fluoxetine.

If a man takes fluoxetine, could it affect fertility or increase the chance of birth defects?

Fluoxetine and other SSRIs have been reported to cause some sexual side effects, such as lower sexual desire or problems with ejaculation. This can affect a man’s fertility (ability to get a woman pregnant). Studies looking at fluoxetine in a small number of men have reported that sperm quality can be affected (but still within the normal range) with long-term fluoxetine use. The sperm quality improved when fluoxetine was stopped. In general, exposures that men have are unlikely to increase risks to a pregnancy.

Talk to your child’s doctor about the risks of giving fluoxetine to your child.

Fluoxetine may cause other side effects. See your doctor if you have any unusual problems while taking fluoxetine.

Paroxetine

Paroxetine is a selective serotonin reuptake inhibitor (SSRI) that has been used to treat depression, generalized anxiety disorder (GAD, excessive worrying that is difficult to control), social anxiety disorder (extreme fear of interacting with others or performing in front of others that interferes with normal life), obsessive compulsive disorder (OCD, bothersome thoughts that won’t go away and the need to perform certain actions over and over), premenstrual dysphoric disorder (PMDD, physical and psychological symptoms that occur before the onset of the menstrual period each month), post-traumatic stress disorder (PTSD, disturbing psychological symptoms that develop after a frightening experience), and panic disorder (sudden, unexpected attacks of extreme fear and worry about these attacks). Paroxetine is also used to treat chronic headaches, diabetic neuropathy (numbness in the hands and feet caused by diabetes), premature ejaculation and hot flashes (sudden feelings of warmth, especially in the face, neck, and chest) in women who are experiencing menopause (stage of life when menstrual periods become less frequent and stop and women may experience other symptoms and body changes). There is not enough information available at this time to know how paroxetine works to treat hot flashes in menopause. Paroxetine is also sometimes used with other medications to treat bipolar disorder (mood that changes from depressed to abnormally excited). Paroxetine may be prescribed for other uses; ask your doctor or pharmacist for more information.

Paroxetine was approved for use in the United States in 1992 and it remains in wide use, with more than 15 million prescriptions being filled yearly ⁴⁵.

Paroxetine is available as tablets of 10, 20, 30 and 40 mg and an oral suspension (liquid) in generic forms and under the brand names of Paxil and Pexeva. The recommended dosage for depression in adults is 20 mg once daily, increasing the dosage by 10 mg increments weekly to a maximum of 50 mg. Controlled release or extended-release (long-acting) tablets are also available that have slightly different dosing recommendations.

The tablets, suspension, and controlled-release tablets are usually taken once daily in the morning or evening, with or without food. The capsules are usually taken once a day at bedtime with or without food. You may want to take paroxetine with food to prevent stomach upset. Take paroxetine at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take paroxetine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Shake the liquid well before each use to mix the medication evenly.

Swallow the extended-release and regular tablets whole; do not chew or crush them.

If you are taking paroxetine tablets, suspension, or controlled-release tablets, your doctor may start you on a low dose of paroxetine and gradually increase your dose, not more than once a week.

Paroxetine capsules contain a lower dose of paroxetine than is needed to treat depression and other forms of mental illness. Do not take paroxetine capsules to treat a mental illness. If you think you have depression or another mental illness, talk to your doctor about treatment.

Paroxetine may help control your symptoms but will not cure your condition. It may take several weeks or longer before you feel the full benefit of paroxetine. Continue to take paroxetine even if you feel well. Do not stop taking paroxetine without talking to your doctor. Your doctor may decrease your dose gradually. If you suddenly stop taking paroxetine tablets, suspension, or controlled-release tablets, you may experience withdrawal symptoms such as depression; mood changes; frenzied or abnormally excited mood; irritability; anxiety; confusion; dizziness; headache; tiredness; numbness or tingling in the arms, legs, hands, or feet; unusual dreams; difficulty falling asleep or staying asleep; nausea; or sweating. Tell your doctor if you experience any of these symptoms when your dose of paroxetine is decreased.

Common side effects of Paroxetine are drowsiness, dyspepsia, nausea, headache, increased sweating, increased appetite, weight gain and sexual dysfunction. Rare but potentially severe adverse events include suicidal ideation and behavior, activation of mania, serotonin syndrome, discontinuation syndrome, increased risk of bleeding, seizures, acute glaucoma, hypersensitivity reactions and embryo-fetal toxicity.

Before taking Paroxetine

You should not use Paroxetine if you are allergic to paroxetine, or if you are also taking pimozide or thioridazine.

Do not use Paroxetine if you have used an monoamine oxidase (MAO) inhibitor in the past 14 days. A dangerous drug interaction could occur. Monoamine oxidase (MAO) inhibitors include isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, rasagiline, phenelzine (Nardil), selegiline (Emsam, Zelapar), and tranylcypromine (Parnate). You must wait at least 14 days after stopping an monoamine oxidase (MAO) inhibitor before you take Paroxetine.

To make sure paroxetine is safe for you, tell your doctor if you have:

• Bipolar disorder (mood disorder with mania and depression)
• Bleeding problems
• Bone problems
• Angle-closure glaucoma. You should know that Paroxetine may cause angle-closure glaucoma, a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision. Talk to your doctor about having an eye examination before you start taking Paroxetine. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, see your doctor or get emergency medical treatment right away.
• Drug addiction
• Hyponatremia (low sodium in the blood)
• Hyponatremia (low sodium in the blood)
• Mania, history of or
• Seizures, history of or
• Sexual problems: Use with caution. May make these conditions worse.
• Kidney disease, severe or
• Liver disease, severe: Use with caution. The effects may be increased because of slower removal of the medicine from the body.
• Suicidal thoughts.

Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson’s disease, migraine headaches, serious infections, or prevention of nausea and vomiting. These medicines may interact with paroxetine and cause a serious condition called serotonin syndrome.

Some young people have thoughts about suicide when first taking an antidepressant. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.

Taking an SSRI antidepressant during pregnancy may cause serious lung problems or other complications in the baby. However, you may have a relapse of depression if you stop taking your antidepressant. Tell your doctor right away if you become pregnant. Do not start or stop taking Paroxetine without your doctor’s advice.

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to Paroxetine or any other medicines. Also tell your doctor if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children

Appropriate studies have not been performed on the relationship of age to the effects of paroxetine in the pediatric population. Safety and efficacy have not been established.

Use of Brisdelle® or paroxetine capsules is not indicated in the pediatric population.

Elderly

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of paroxetine in the elderly. However, elderly patients may be more sensitive to the effects of Paroxetine than younger adults, and are more likely to have hyponatremia (low sodium in the blood), which may require caution and an adjustment in the dose for patients receiving paroxetine.

Pregnancy

Paroxetine is contraindicated in pregnancy and is classified as category D/X due to its teratogenic effects in causing cardiovascular defects, specifically heart malformations if prescribed in the first trimester ²⁴.

In some women, paroxetine may raise the levels of a hormone called prolactin ⁴⁶. High levels of prolactin can stop ovulation (part of the menstrual cycle when an ovary releases an egg). This can make it harder to get pregnant. Paroxetine has also been associated with changes in sexual function such as less desire to have sex ⁴⁶.

Miscarriage is common and can occur in any pregnancy for many different reasons. Some studies suggest that taking paroxetine may slightly increase the chance of miscarriage. However, research also shows that depression itself may increase the chance of miscarriage. This makes it hard to know if an increased chance of miscarriage is due to medication, the underlying condition, or other factors.

Every pregnancy starts out with a 3-5% chance of having a birth defect. This is called the background risk. Some studies suggest that exposure to paroxetine in the first trimester might be associated with a small increased chance for heart defects. Other studies did not find a possible increased risk. The background rate of heart defects for any pregnancy is about 1 in 100 (1%). If there is an increased chance of birth defects with paroxetine use in the first trimester, it is expected to be small. Paroxetine exposure in pregnancy has not been shown to increase the chance of other birth defects.

Some studies suggest a higher chance for preterm delivery (birth before week 37) with the use of an SSRI such as paroxetine, while others do not. Conditions such as depression may increase the chance of pregnancy-related problems, such as preterm delivery. This makes it hard to know if it is the medication, the condition being treating, or other factors that are increasing the chance of pregnancy-related problems.

Some, but not all, studies have suggested that when women who are pregnant take SSRIs during the second half of the pregnancy, their babies might have a higher chance for a serious lung condition called persistent pulmonary hypertension ⁴⁶. Persistent pulmonary hypertension happens in 1 or 2 out of 1,000 births. Among the studies looking at this, the overall chance for pulmonary hypertension when an SSRI was used in pregnancy was less than 1/100 (less than 1%).

The use of paroxetine during pregnancy can cause temporary symptoms in newborns soon after birth. These symptoms are sometimes referred to as withdrawal. Symptoms may include jitteriness, increased muscle tone, irritability, changes in sleep patterns, tremors, trouble eating, and trouble breathing. These symptoms are usually mild and go away on their own. Some babies may need to stay in a special care nursery for several days. Not all babies exposed to paroxetine will have these symptoms. It is important that your doctor know you are taking paroxetine so that if symptoms occur your baby can get the care that’s best for them.

It is not known if paroxetine can increase the chance for behavior or learning issues. One study looking at prescriptions for SSRIs including paroxetine suggested an increased chance of autism spectrum disorder. Studies based on filled prescriptions/prescription records cannot tell if a person took the medication, so it is hard to know if the outcomes are related to the medication or other factors. Also, this study did not look at factors such as other exposures, paternal mental illness, or other family history of autism. Another prescription study did not report an increased chance for autism spectrum disorder.

One study looking at pregnancies exposed at least during the third trimester to SSRIs including paroxetine reported no differences in developmental outcomes between the exposed 46 infants or the unexposed 23 infants at 2 and 8 months of age. A follow-up study on some of these children found no difference in behaviors such as emotional reactivity, withdrawal, irritability, depression, or anxiety in the exposed group (22 children) when compared to the group that was not exposed to paroxetine (14 children).

Breastfeeding

Paroxetine passes into breastmilk in small amounts. In some cases, mild side effects have been reported. If you suspect the baby has any symptoms (trouble sleeping, restlessness, or increased crying), contact the child’s doctor. Be sure to talk to your doctor about all your breastfeeding questions. An alternative to Paroxetine should be prescribed or you should stop breastfeeding while using Paroxetine.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking Paroxetine, it is especially important that your doctor know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Sertraline

Sertraline is a selective serotonin reuptake inhibitor (SSRI) medication that has been used to treat depression, obsessive-compulsive disorder (OCD, bothersome thoughts that won’t go away and the need to perform certain actions over and over), panic attacks (sudden, unexpected attacks of extreme fear and worry about these attacks), and major anxiety disorders including social anxiety disorder, post-trauma stress disorder (PTSD, disturbing psychological symptoms that develop after a frightening experience) and generalized anxiety disorder (GAD), panic disorder, premenstrual dysphoric disorder [PMDD] (a severe form of premenstrual syndrome [PMS] with mood swings, irritability, bloating, and breast tenderness), and social anxiety disorder (extreme fear of interacting with others or performing in front of others that interferes with normal life). Sertraline is also used for headache, diabetic neuropathy and premature ejaculation. Sertraline works by blocking the reuptake of serotonin in your brain neurons, thus increasing serotonin levels in your brain which is associated with its psychiatric effects.

Sertraline was approved for use in the United States in 1991, and it remains in wide use, with almost 40 million prescriptions being filled yearly ⁴⁷.

Sertraline is available as tablets of 25, 50 and 100 mg and as an oral suspension (liquid) in multiple generic forms and under the brand name of Zoloft. Sertraline is usually taken once daily in the morning or evening. The recommended dosage for depression in adults is 50 or 100 mg once daily, increasing the dosage by 25 or 50 mg increments to a maximum of 200 mg. Take sertraline at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sertraline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

To treat premenstrual dysphoric disorder (PMDD), sertraline is taken once a day, either every day of the month or on certain days of the month.

Sertraline concentrate must be diluted before use. Immediately before taking it, use the provided dropper to remove the amount of concentrate your doctor has told you to take. Mix the concentrate with 4 ounces (1/2 cup [120 milliliters]) of water, ginger ale, lemon or lime soda, lemonade, or orange juice. After mixing, the diluted solution may be hazy; this is normal. Do not mix the concentrate with any liquids other than the ones listed. Drink the diluted solution immediately.

Your doctor may start you on a low dose of sertraline and gradually increase your dose, not more than once a week.

It may take a few weeks or longer before you feel the full benefit of sertraline. Continue to take sertraline even if you feel well. Do not stop taking sertraline without talking to your doctor. If you suddenly stop taking sertraline, you may experience withdrawal symptoms such as nausea, sweating, depression, mood changes, frenzied or abnormally excited mood, irritability, anxiety, confusion, dizziness, headache, tiredness, seizures, ringing in the ears, numbness or tingling in the arms, legs, hands, or feet, difficulty falling asleep or staying asleep.

Common side effects of Sertraline are drowsiness, dyspepsia, nausea, headache, increased sweating, increased appetite, weight gain and sexual dysfunction. Rare but potentially severe adverse events include suicidal ideation and behavior, activation of mania, serotonin syndrome, discontinuation syndrome, increased risk of bleeding, seizures, acute glaucoma, hypersensitivity reactions and embryo-fetal toxicity.

Before taking Sertraline

You should not use sertraline if you are allergic to it, or if you also take pimozide. Do not use the liquid form of Sertraline if you take disulfiram (Antabuse).

if you have used an MAO inhibitor in the past 14 days, a dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, and tranylcypromine. Wait at least 14 days after stopping an MAO inhibitor before you take sertraline.

Tell your doctor if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson’s disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with sertraline could cause a serious condition called serotonin syndrome.

To make sure sertraline is safe for you, tell your doctor if you have ever had:

• An allergy or sensitivity to aspirin or tartrazine (food dye) or latex (Zoloft oral solution – the dropper dispenser contains natural rubber)
• Bipolar disorder (mood disorder with mania and depression)
• Bleeding problems or if you take warfarin (Coumadin, Jantoven)
• Diabetes
• Angle-closure glaucoma. You should know that Paroxetine may cause angle-closure glaucoma, a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision. Talk to your doctor about having an eye examination before you start taking Paroxetine. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, see your doctor or get emergency medical treatment right away.
• Heart rhythm problems (eg, long QT syndrome)
• High blood pressure
• Hyponatremia (low sodium in the blood)
• Mania or hypomania
• Purpura (purplish or brownish-red discoloration of the skin)
• Seizures
• Sexual problems: Use with caution. May make these conditions worse.
• Kidney disease
• Liver disease: Use with caution. The effects may be increased because of slower removal of the medicine from the body.
• Stroke

Some young people may have increased suicidal thoughts when first starting a medicine to treat depression. Your doctor will need to check your progress on a regular basis. Your family or caregivers should also watch for sudden changes in your behavior.

Sertraline is approved for use in children at least 6 years old, only to treat obsessive-compulsive disorder but not depression.

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to Sertraline or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children

Appropriate studies have not been performed on the relationship of age to the effects of sertraline in children with depression, panic disorder, premenstrual dysphoric disorder (PMDD), posttraumatic stress disorder (PTSD), and social anxiety disorder (SAD), and in children younger than 6 years of age with obsessive-compulsive disorder. Safety and efficacy have not been established.

Elderly

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of sertraline in the elderly. However, elderly patients are more likely to have hyponatremia (low sodium in the blood), age-related kidney, liver, or heart problems which may require caution and an adjustment in the dose for patients receiving sertraline.

Pregnancy

It is not known if sertraline can make it harder to get pregnant. One study found that women who take SSRIs have a slightly lower chance of getting pregnant. However, some conditions, including depression, can make it harder to get pregnant. This makes it hard to know if the medication, the condition being treated, or other factors might affect fertility.

Miscarriage is common and can occur in any pregnancy for many different reasons. Use of sertraline and the chance of miscarriage has not been well studied. One study found no differences in the chance of miscarriage in women who filled prescriptions for sertraline during the first 35 days of pregnancy and those who stopped filling prescriptions before pregnancy. Also, some conditions, including depression, may increase the chance of miscarriage. This makes it hard to know if the medication, the condition being treated, or other factors might affect the chance of miscarriage.

Every pregnancy starts out with a 3-5% chance of having a birth defect. This is called the background risk. There are reports of more than 25,000 pregnancies exposed to sertraline. Some studies have suggested an increased chance for heart defects or other birth defects. However, most studies have not found an increased chance of birth defects when sertraline is used in pregnancy. Overall, the available data does not suggest that sertraline increases the chance of birth defects above the background risk.

Some studies suggest a higher chance for pregnancy-related problems, such as preterm delivery (birth before week 37) or low birth weight (weighing less than 5 pounds, 8 ounces [2500 grams] at birth) with the use of sertraline in pregnancy. However, research has also shown that when conditions such as depression or anxiety are untreated or undertreated during pregnancy, there could be an increased chance for pregnancy complications. This makes it hard to know if it is the medication, the underlying condition, or other factors that might increase the chance for these problems.

Some, but not all, studies have suggested that when women who are pregnant take SSRIs during the second half of pregnancy, their babies might have an increased chance for a serious lung condition called persistent pulmonary hypertension (PPH). Persistent pulmonary hypertension happens in 1 or 2 out of 1,000 births. A recent report that combined results from several studies suggested the chance for persistent pulmonary hypertension might be increased if an SSRI was used during pregnancy. However, it was not clear if this was due to medication exposure or to other exposures that people who take SSRIs have in common, such as higher rates of smoking. Data from studies suggest the overall chance for persistent pulmonary hypertension when an SSRI is used in pregnancy is less than 1/100 (less than 1%).

The use of sertraline during pregnancy can cause temporary symptoms in newborns soon after birth. These symptoms are sometimes referred to as withdrawal. Symptoms can include irritability, jitteriness, tremors (shivering), constant crying, changes in sleep patterns, lower muscle tone (hypotonia), skin discoloration (cyanosis), problems with eating, trouble controlling body temperature, and problems with breathing (apnea). In most cases, these symptoms are mild and go away within a couple weeks with no treatment required. Some babies may need to stay in the nursery or neonatal intensive care unit (NICU) until the symptoms go away. Not all babies exposed to sertraline will have these symptoms. It is important that your doctor know you are taking sertraline so that if symptoms do occur, your baby can get the care that is best for them.

One study on a small number of children who were exposed to SSRIs during pregnancy reported a lower score on motor skill tests than other children. Another small study looked at behaviors in children ages 4-5 years old. This study found no difference in behavior between children who were exposed to sertraline or other SSRIs during pregnancy and those children who were not.

Breastfeeding

Sertraline gets into breastmilk in small amounts. Most reports show no problems for babies who are exposed to sertraline through breast milk. Babies who were also exposed to sertraline in the third trimester of pregnancy may have a lower chance of withdrawal after birth if they are breastfed. Be sure to talk to your doctor about all your breastfeeding questions.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking Sertraline, it is especially important that your doctor know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Vilazodone

Vilazodone is a serotonin reuptake inhibitor (SSRI) and partial serotonin receptor agonist also called serotonin modulators ⁴⁸, ⁴⁹. Vilazodone works by blocking the reuptake of serotonin in your brain neurons, thus increasing serotonin levels in your brain which is associated with its psychiatric effects. Vilazodone is also a partial serotonin (5-HT1A) receptor agonist, which may add to its antidepressant effects. Vilazodone is used to treat depression.

Vilazodone was approved for use in the United States in 2011 for use in treatment of major depressive disorder ⁴⁸. However, there is limited clinical experience with its use.

Vilazodone is available as tablets of 10, 20 and 40 mg under the brand name Viibryd. Take vilazodone at around the same time every day. The recommended initial dose of vilazodone in adults is 10 mg daily, which can then be increased to the typical maintenance dose of 40 mg once daily. Vilazodone is usually taken with food once a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take vilazodone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on a low dose of vilazodone and gradually increase your dose, not more than once every 7 days.

Vilazodone controls depression but does not cure it. It may take several weeks before you feel the full benefit of vilazodone. Continue to take vilazodone even if you feel well. Do not stop taking vilazodone without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking vilazodone, you may experience withdrawal symptoms such as dizziness; nausea; headache; confusion; irritability; agitation; difficulty falling asleep or staying asleep; anxiety; extreme tiredness; seizures; pain, burning, or tingling in the hands or feet; frenzied or abnormally excited mood; or sweating. Tell your doctor if you experience any of these symptoms while you are decreasing your dose of vilazodone or soon after you stop taking vilazodone.

Common, non-serious side effects of Vilazodone include diarrhea, nausea, fatigue, drowsiness, headache, insomnia, weight gain and sexual dysfunction. Vilazodone overdose is associated with acute serotonin syndrome. Rare, but potentially severe adverse effects include suicidal thinking and behavior, activation of symptoms of mania, serotonin syndrome, sexual dysfunction, hyponatremia and hypersensitivity reactions.

Before taking Vilazodone

Before taking vilazodone:

• Tell your doctor and pharmacist if you are allergic to vilazodone, any other medications, or any of the ingredients in vilazodone tablets. Ask your pharmacist or check the Medication Guide for a list of the ingredients.
• Do not use an monoamine oxidase (MAO) inhibitor within 14 days before or 14 days after you take vilazodone. A dangerous drug interaction could occur. Monoamine oxidase (MAO) inhibitors include isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, rasagiline, phenelzine (Nardil), selegiline (Emsam, Zelapar), and tranylcypromine (Parnate). You must wait at least 14 days after stopping an monoamine oxidase (MAO) inhibitor before you take vilazodone.
• Tell your doctor if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson’s disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with vilazodone could cause a serious condition called serotonin syndrome.
• Vilazodone is not approved for use by anyone younger than 18 years old.
• Some young people have thoughts about suicide when first taking an antidepressant. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.
• Some medications should not be taken with vilazodone. Other medications may cause dosing changes or extra monitoring when taken with vilazodone. Make sure you have discussed any medications you are currently taking or plan to take before starting vilazodone with your doctor and pharmacist. Before starting, stopping, or changing any medications while taking vilazodone, please get the advice of your doctor or pharmacist.
• The following nonprescription or herbal products may interact with vilazodone: St. John’s wort; tryptophan; aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin) and naproxen (Aleve). Be sure to let your doctor and pharmacist know that you are taking these medications before you start taking vilazodone. Do not start any of these medications while taking vilazodone without discussing with your doctor.
• Tell your doctor if you have a low level of sodium in your blood (hyponatremia) or glaucoma (increased pressure in the eye that may cause loss of sight), and if you drink or have ever drunk large amounts of alcohol, Also tell your doctor if you have or have ever had bleeding problems, seizures, or liver disease.
• Tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breast-feeding. If you become pregnant while taking vilazodone, call your doctor. Vilazodone may cause problems in newborns following delivery if it is taken during the last months of pregnancy. If you are pregnant, your name may be listed on a pregnancy registry to track the effects of vilazodone on the baby.
• If you are having surgery, including dental surgery, tell the doctor or dentist that you are taking vilazodone.
• You should know that vilazodone may make you drowsy and affect your judgment and thinking. Do not drive a car or operate machinery until you know how this medication affects you.
• Ask your doctor about the safe use of alcoholic beverages while you are taking vilazodone. Alcohol can make the side effects from vilazodone worse.
• You should know that vilazodone may cause angle-closure glaucoma (a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision). Talk to your doctor about having an eye examination before you start taking this medication. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, call your doctor or get emergency medical treatment right away.

Tell your doctor about all your current medicines. Many drugs can affect vilazodone, especially:

• any other antidepressants
• mephenytoin
• St. John’s wort
• tramadol
• a diuretic or “water pill”
• medicine to treat anxiety, mood disorders, or mental illness such as schizophrenia
• a blood thinner: warfarin, Coumadin, Jantoven
• migraine headache medicine: sumatriptan, Imitrex, Maxalt, Treximet, and others.

This list is not complete and many other drugs may affect vilazodone. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.

Pregnancy

It is not known if vilazodone can make it harder to get pregnant ⁵⁰.

Miscarriage is common and can occur in any pregnancy for many different reasons. Studies have not been done to see if vilazodone increases the chance for miscarriage. However, depression itself might increase the chance for miscarriage.

Every pregnancy starts out with a 3-5% chance of having a birth defect. This is called the background risk. Animal studies did not find an increased chance of birth defects. We have been unable to locate studies on the use of vilazodone in human pregnancies.

Studies have not been done to see if vilazodone can cause other pregnancy-related problems, such as preterm delivery (birth before week 37) or low birth weight (weighing less than 5 pounds, 8 ounces [2500 grams] at birth).

It is not known if the use of vilazodone during pregnancy can cause withdrawal symptoms in a baby after birth. The use of other antidepressants during pregnancy has been associated with temporary symptoms in some newborns after birth. These symptoms are sometimes referred to as withdrawal. Symptoms may include jitteriness, increased muscle tone, irritability, changes in sleep patterns, tremors, trouble eating, and trouble breathing. These symptoms are usually mild and go away on their own. Some babies may need to stay in a special care nursery for several days. Not all babies exposed to an antidepressant will have these symptoms. It is important that your doctor know you are taking vilazodone so that if symptoms occur your baby can get the best care.

Studies have not been done to see if vilazodone use in pregnancy can cause behavior or learning issues for the child.

Breastfeeding

It is not known if vilazodone gets into breast milk or causes side effects for a baby who receives the milk. The benefit of continuing vilazodone while breastfeeding may outweigh the risks of an untreated mental health condition or the risks of not breastfeeding. Your doctor can talk with you about vilazodone and what treatment is best for you. Be sure to talk to your doctor about all of your breastfeeding questions.

Vilazodone dosage

Adult Dose for Depression

• Initial dose: 10 mg orally once a day for 7 days, followed by 20 mg orally once a day for an additional 7 days
• Maintenance dose: 40 mg orally once a day

Take vilazodone with food ⁷.

Missed Dose

If you miss a dose of vilazodone, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
