What is ketoprofen
Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) used in treatment of acute pain and chronic arthritis. Ketoprofen is a propionic acid derivate similar to naproxen and ibuprofen and nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic activities. Like other nonsteroidal anti-inflammatory drugs (NSAIDs), ketoprofen works by inhibiting the activity of the enzymes cyclo-oxygenase 1 (COX-1) and 2 (COX-2), resulting in a decreased formation of precursors of prostaglandins and thromboxanes hormones that cause inflammation and pain in the body. Ketoprofen also causes a decrease in the formation of thromboxane A2 synthesis, by thromboxane synthase, thereby inhibiting platelet aggregation.
Ketoprofen was approved in the United States in 1986 and is still widely used. Current indications include chronic joint pain due to osteoarthritis and rheumatoid arthritis as well as mild-to-moderate acute pain and menstrual pain (dysmenorrhea). The recommended dose in adults with chronic arthritis is 50 to 75 mg 3 or 4 times per day with a maximum dose of 300 mg daily. Ketoprofen is available by prescription in the form of capsules or tablets of 25, 50 and 75 mg in both generic and trade formulations (Orudis, Oruvail, among others). Extended release formulations of 100, 150 and 200 mg are also available for once daily dosing. Ketoprofen is also available in over-the-counter formulations of 12.5 mg tablets for treatment of mild-to-moderate pain and dysmenorrhea.
Ketoprofen is available in the following dosage forms:
- Extended Release capsule,
- Regular capsule.
Only ketoprofen extended-release capsules are used for treating arthritis. This form of ketoprofen will not work fast enough to treat acute pain.
The ketoprofen regular capsule is used to treat menstrual pain.
As with other NSAIDs, ketoprofen is generally well tolerated, but side effects can include headache, dizziness, somnolence, gastrointestinal upset, nausea, abdominal discomfort, diarrhea, peripheral edema and hypersensitivity reactions.
Ketoprofen has been linked to a low rate of serum enzyme elevations during therapy and to rare instances of clinically apparent acute liver injury.
People who take nonsteroidal anti-inflammatory drugs (NSAIDs) other than aspirin, such as ketoprofen, may have a higher risk of having a heart attack or a stroke than people who do not take these medications. These events may happen without warning and may cause death. This risk may be higher for people who take NSAIDs for a long time. Do not take an NSAID such as ketoprofen if you have recently had a heart attack, unless directed to do so by your doctor. Tell your doctor if you or anyone in your family has or has ever had heart disease, a heart attack, or a stroke, if you smoke, and if you have or have ever had high cholesterol, high blood pressure, or diabetes. Get emergency medical help right away if you experience any of the following symptoms: chest pain, shortness of breath, weakness in one part or side of the body, or slurred speech.
If you will be undergoing a coronary artery bypass graft (CABG; a type of heart surgery), you should not take ketoprofen right before or right after the surgery.
NSAIDs such as ketoprofen may cause ulcers, bleeding, or holes in the stomach or intestine. These problems may develop at any time during treatment, may happen without warning symptoms, and may cause death. The risk may be higher for people who take NSAIDs for a long time, are older in age, have poor health, or drink more than three alcoholic drinks per day while taking ketoprofen. Tell your doctor if you drink large amounts of alcohol or if you take any of the following medications: anticoagulants (‘blood thinners’) such as warfarin (Coumadin, Jantoven); aspirin; other NSAIDs such as ibuprofen (Advil, Motrin) or naproxen (Aleve, Naprosyn); or oral steroids such as dexamethasone, methylprednisolone (Medrol), and prednisone (Rayos); selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), fluoxetine (Prozac, Sarafem, Selfemra, in Symbyax), fluvoxamine (Luvox), paroxetine (Brisdelle, Paxil, Pexeva), and sertraline (Zoloft); or serotonin norepinephrine reuptake inhibitors (SNRIs) such as desvenlafaxine (Khedezla, Pristiq), duloxetine (Cymbalta), and venlafaxine (Effexor XR). Also tell your doctor if you have or have ever had ulcers or bleeding in your stomach or intestines or other bleeding disorders. If you experience any of the following symptoms, stop taking ketoprofen and call your doctor: stomach pain, heartburn, vomit that is bloody or looks like coffee grounds, blood in the stool, or black and tarry stools.
Keep all appointments with your doctor and the laboratory. Your doctor will monitor your symptoms carefully and will probably order certain tests to check your body’s response to ketoprofen. Be sure to tell your doctor how you are feeling so that your doctor can prescribe the right amount of medication to treat your condition with the lowest risk of serious side effects.
Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with prescription ketoprofen and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) to obtain the Medication Guide.

Ketoprofen vs Ibuprofen
Ibuprofen is also a nonsteroidal anti-inflammatory drug (NSAID) used to treat mild to moderate pain, and helps to relieve symptoms of arthritis (osteoarthritis, rheumatoid arthritis, or juvenile arthritis), such as inflammation, swelling, stiffness, and joint pain. Ibuprofen does not cure arthritis and will help you only as long as you continue to take it.
In addition, ibuprofen can be used to treat fever, menstrual cramps, and other conditions as determined by your doctor. Ibuprofen is also sometimes used to treat ankylosing spondylitis (arthritis that mainly affects the spine), gouty arthritis (joint pain caused by a build-up of certain substances in the joints), and psoriatic arthritis (arthritis that occurs with a long-lasting skin disease that causes scaling and swelling).
Ibuprofen is available both over-the-counter (OTC) and with your doctor’s prescription.
Ibuprofen is available in the following dosage forms:
- Tablet, Chewable
- Tablet
- Suspension
- Capsule, Liquid Filled
Prescription ibuprofen comes as a tablet to take by mouth. It is usually taken three or four times a day for arthritis or every 4 to 6 hours as needed for pain. Nonprescription ibuprofen comes as a tablet, chewable tablet, suspension (liquid), and drops (concentrated liquid). Adults and children older than 12 years of age may usually take nonprescription ibuprofen every 4 to 6 hours as needed for pain or fever. Children and infants may usually be given nonprescription ibuprofen every 6 to 8 hours as needed for pain or fever, but should not be given more than 4 doses in 24 hours. Ibuprofen may be taken with food or milk to prevent stomach upset. If you are taking ibuprofen on a regular basis, you should take it at the same time(s) every day. Follow the directions on the package or prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ibuprofen exactly as directed. Do not take more or less of it or take it more often than directed by the package label or prescribed by your doctor.
Ibuprofen comes alone and in combination with other medications. Some of these combination products are available by prescription only, and some of these combination products are available without a prescription and are used to treat cough and cold symptoms and other conditions. If your doctor has prescribed a medication that contains ibuprofen, you should be careful not to take any nonprescription medications that also contain ibuprofen.
If you are selecting a product to treat cough or cold symptoms, ask your doctor or pharmacist for advice on which product is best for you. Check nonprescription product labels carefully before using two or more products at the same time. These products may contain the same active ingredient(s) and taking them together could cause you to receive an overdose. This is especially important if you will be giving cough and cold medications to a child.
Nonprescription cough and cold combination products, including products that contain ibuprofen, can cause serious side effects or death in young children. Do not give these products to children younger than 4 years of age. If you give these products to children 4 to 11 years of age, use caution and follow the package directions carefully.
If you are giving ibuprofen or a combination product that contains ibuprofen to a child, read the package label carefully to be sure that it is the right product for a child of that age. Do not give ibuprofen products that are made for adults to children.
Before you give an ibuprofen product to a child, check the package label to find out how much medication the child should receive. Give the dose that matches the child’s age on the chart. Ask the child’s doctor if you don’t know how much medication to give the child.
Shake the suspension and drops well before each use to mix the medication evenly. Use the measuring cup provided to measure each dose of the suspension, and use the dosing device provided to measure each dose of the drops.
The chewable tablets may cause a burning feeling in the mouth or throat. Take the chewable tablets with food or water.
Stop taking nonprescription ibuprofen and call your doctor if your symptoms get worse, you develop new or unexpected symptoms, the part of your body that was painful becomes red or swollen, your pain lasts for more than 10 days, or your fever lasts more than 3 days. Stop giving nonprescription ibuprofen to your child and call your child’s doctor if your child does not start to feel better during the first 24 hours of treatment. Also stop giving nonprescription ibuprofen to your child and call your child’s doctor if your child develops new symptoms, including redness or swelling on the painful part of his body, or if your child’s pain or fever get worse or lasts longer than 3 days.
Do not give nonprescription ibuprofen to a child who has a sore throat that is severe or does not go away, or that comes along with fever, headache, nausea, or vomiting. Call the child’s doctor right away, because these symptoms may be signs of a more serious condition.
What is ketoprofen used for?
Ketoprofen is used to relieve pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints) and rheumatoid arthritis (arthritis caused by swelling of the lining of the joints). Prescription ketoprofen capsules are also used to relieve pain, including menstrual pain (pain that occurs before or during a menstrual period). Ketoprofen over the counter (ketoprofen OTC) is used to relieve minor aches and pain from headaches, menstrual periods, toothaches, the common cold, muscle aches, and backaches, and to reduce fever. Ketoprofen is in a class of medications called NSAIDs. It works by stopping the body’s production of a substance that causes pain, fever, and inflammation.
Ketoprofen is also sometimes used to treat juvenile rheumatoid arthritis (a type of arthritis that affects children), ankylosing spondylitis (arthritis that mainly affects the spine), Reiter’s syndrome (condition in which many parts of the body including the joints, eyes, genitals, bladder, and digestive system become swollen), shoulder pain caused by bursitis (inflammation of a fluid-filled sac in the shoulder joint) and tendinitis (inflammation of the tissue that connects muscle to bone), and gouty arthritis (attacks of joint pain caused by a build-up of certain substances in the joints). Talk to your doctor about the risks of using ketoprofen for your condition.
Ketoprofen is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Ketoprofen dosage
Prescription ketoprofen comes as a capsule and extended-release (long-acting) capsule to take by mouth. The capsules are usually taken three or four times a day for arthritis or every 6 to 8 hours as needed for pain. The extended-release capsules are usually taken once daily. If you take ketoprofen regularly, take it at around the same times every day.
Ketoprofen over the counter (ketoprofen OTC) comes as a tablet to take by mouth. It is usually taken with a full glass of water or other liquid every 4 to 6 hours as needed.
Follow the directions on the package or prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ketoprofen exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor or written on the label.
Ketoprofen may be taken with food or milk to prevent upset stomach. Your doctor may also recommend that you take ketoprofen with an antacid to reduce stomach upset.
Your doctor may start you on an average dose of prescription ketoprofen and may increase or decrease on your dose depending on how well you respond to the medication and the side effects you experience. Follow these directions carefully.
Stop taking nonprescription ketoprofen and call your doctor if your symptoms get worse, you develop new or unexpected symptoms, the part of your body that was painful becomes red or swollen, your pain lasts for more than 10 days or your fever lasts for more than 3 days.
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.

How well someone does depends on the amount of ketoprofen that was swallowed and how quickly treatment is received. The faster medical help is given, the better the chance for recovery.
A mild overdose of ketoprofen does not usually cause serious problems. The person may have some stomach pain and vomiting (possibly with blood).
However, a large amount of internal bleeding is possible, and a blood transfusion may be needed. Passing a tube with a camera through the mouth into the stomach may be needed to stop the internal bleeding.
A large overdose can cause serious damage to children and adults. Death may occur.
