What is Pepto Bismol

Pepto-Bismol is an antacid and anti-diarrhea medication. Pepto-Bismol is used to treat diarrhea in adults and children 12 years of age and older. Pepto-Bismol is also used to relieve the symptoms of an upset stomach, such as heartburn, indigestion, and nausea in adults and children 12 years of age and older. The active ingredient in Pepto-Bismol is bismuth subsalicylate.

Pepto-Bismol is available without a prescription. However, if you are taking Pepto Bismol (bismuth subsalicylate) medicine for diarrhea, check with your doctor:

  • if your symptoms do not improve within 2 days or if they become worse.
  • if you also have a high fever.

Pepto Bismol (bismuth subsalicylate) is available in the following dosage forms:

  • Suspension
  • Tablet
  • Tablet, Chewable

How does Pepto Bismol work?

Pepto Bismol (bismuth subsalicylate) is in a class of medications called antidiarrheal agents. It works by decreasing the flow of fluids and electrolytes into the bowel, reduces inflammation within the intestine, and may kill the organisms that can cause diarrhea.

Why does Pepto-Bismol sometimes darken the tongue/stool and how long does it last?

This discoloration is temporary and harmless. The active ingredient in Pepto-Bismol contains bismuth. When a small amount of bismuth combines with trace amounts of sulfur in your saliva and gastrointestinal tract, a black-colored substance (bismuth sulfide) is formed. This discoloration is temporary and harmless. It can last several days after you stop taking Pepto-Bismol. Individual bowel habits, your age (the intestinal tract slows down with age), and the amount of the product taken all help to determine how long Pepto-Bismol is in your system.

Can I give Pepto-Bismol to my child?

Pepto-Bismol is indicated only for adults and children 12 years and over. Use only as directed.

For children 2 years and older, Children’s Pepto Antacid (contains Calcium Carbonate 400 mg in each Children’s Pepto Antacid chewable tablet) can be used to relieve heartburn, acid indigestion, sour stomach, and upset stomach due to these symptoms. Note the difference between Children’s Pepto Antacid that contains Calcium Carbonate unlike the actual Pepto-Bismol that contains Bismuth subsalicylate. Subsalicylate is chemically related to aspirin; therefore, includes similar warning statements to aspirin.

I have been giving Pepto-Bismol to my child when he/she had an upset stomach – should I be concerned?

Pepto-Bismol is indicated only for adults and children 12 years and over. Use only as directed.

Pepto Bismol contains both bismuth and subsalicylate. Subsalicylate is chemically related to aspirin; therefore, includes similar warning statements. Hepatic injury has been reported with chronic therapeutic use 1). Salicylates have been linked with Reye’s syndrome in children. Hypoglycemia may develop, especially in children 2).

The acute ingestion of less than 150 mg/kg or 6.5 g of aspirin equivalent, whichever is less, is not expected to cause significant toxicity.

In young children, the initial respiratory alkalosis from salicylate intoxication is transient, they often have a predominant metabolic acidosis (and in severe cases also respiratory alkalosis) on presentation.

What does the label say about Reye’s syndrome and Pepto-Bismol?

Children and teenagers who have or are recovering from chicken pox or flu-like symptoms should not use Pepto-Bismol. When using this product, if changes in behavior with nausea or vomiting occur, consult a doctor because these symptoms could be an early sign of Reye’s syndrome, a rare but serious illness. Subsalicylate is chemically related to aspirin; therefore, includes similar warning statements.

Before taking Pepto Bismol – Precautions

In deciding to use Pepto Bismol, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

  • tell your doctor or pharmacist if you are allergic to salicylate pain relievers such as aspirin, choline magnesium trisalicylate, choline salicylate (Arthropan), diflunisal (Dolobid), magnesium salicylate (Doan’s, others), and salsalate (Argesic, Disalcid, Salgesic); or any other medication.
  • check the labels of all over-the-counter (OTC), nonprescription, and prescription medicines you now take. If any contain aspirin or other salicylates, be especially careful. Using other salicylate-containing products while taking Pepto Bismol (bismuth subsalicylate) may lead to overdose. If you have any questions about this, check with your health care professional or pharmacist.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to talk to your doctor or pharmacist about taking Pepto Bismol (bismuth subsalicylate) if you take: anticoagulants (‘blood thinners’) such as warfarin (Coumadin); a daily aspirin; or medication for diabetes, arthritis or gout.
  • if you are taking tetracycline antibiotics such as demeclocycline (Declomycin), doxycycline (Doryx, Vibramycin), minocycline (Dynacin, Minocin), and tetracycline (Sumycin), take them at least 1 hour before or 3 hours after taking Pepto Bismol (bismuth subsalicylate).
  • ask your doctor before taking this medication if you have ever had an ulcer, bleeding problem, stools that are bloody or blackened, or kidney disease. Also ask your doctor before taking Pepto Bismol (bismuth subsalicylate) if you have a fever or mucus in your stool. If you will be giving Pepto Bismol (bismuth subsalicylate) to a child or teenager, tell the child’s doctor if the child has any of the following symptoms before he or she receives the medication: vomiting, listlessness, drowsiness, confusion, aggression, seizures, yellowing of the skin or eyes, weakness, or flu-like symptoms. Also tell the child’s doctor if the child has not been drinking normally, has had excessive vomiting or diarrhea, or appears dehydrated.
  • ask your doctor about taking this medication if you are pregnant or are breast-feeding.

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

  • Do not take more than 8 doses in one day (24 hours).

Shake the liquid medicine well just before you measure a dose. Measure the liquid with a special dose-measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

  • The chewable tablet must be chewed before you swallow it.

Pepto Bismol (bismuth subsalicylate) can cause you to have a black or darkened tongue. This is a harmless side effect.

This medication can also cause unusual results with certain medical tests, thyroid scans, or stomach x-rays. Tell any doctor who treats you that you have recently taken Pepto Bismol (bismuth subsalicylate).

Storage

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Do not freeze.

Keep out of the reach of children. In case of Pepto Bismol overdose, call the Poison Control Helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help.

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

Pediatric patients

This medicine should NOT be used in children younger than 12 years of age. The fluid loss caused by diarrhea may result in a severe condition. In older children with diarrhea, medicine for diarrhea may be used, but it is also very important that a sufficient amount of liquids be given to replace the fluid lost by the body. If you have any questions about this, check with your health care professional.

Also, children are usually more sensitive to the effects of salicylates, especially if they have a fever or have lost large amounts of body fluid because of vomiting, diarrhea, or sweating.

The bismuth in Pepto Bismol may cause severe constipation in children.

In addition, do not use Pepto Bismol (bismuth subsalicylate) to treat nausea or vomiting in children or teenagers who have or are recovering from the flu or chickenpox. If nausea or vomiting is present, check with the child’s doctor immediately because this could be an early sign of Reye’s syndrome.

Geriatric patients

The fluid loss caused by diarrhea may result in a severe condition. For this reason, elderly persons with diarrhea should not take this medicine without first checking with their doctor. It is also very important that a sufficient amount of liquids be taken to replace the fluid lost by the body. If you have any questions about this, check with your health care professional.

Also, the elderly may be more sensitive to the effects of salicylates. This may increase the chance of side effects during treatment. In addition, the bismuth in this medicine may cause severe constipation in the elderly.

Breastfeeding

Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to Pepto Bismol (bismuth subsalicylate) should be prescribed or you should stop breastfeeding while using Pepto Bismol (bismuth subsalicylate).

Diabetic patients

  • False urine sugar test results may occur if you are regularly taking large amounts of bismuth subsalicylate or other salicylates.
  • Smaller doses or occasional use of Pepto Bismol (bismuth subsalicylate) usually will not affect urine sugar tests. However, check with your health care professional (especially if your diabetes is not well-controlled) if:
    • you are not sure how much salicylate you are taking every day.
    • you notice any change in your urine sugar test results.
    • you have any other questions about this possible problem

Pepto Bismol Pregnancy and Breastfeeding

Pepto Bismol Pregnancy Warnings

Safety has not been established during pregnancy; use is NOT recommended.

US FDA pregnancy category: Not assigned

Animal studies are inadequate. There are no controlled data in human pregnancy. Bismuth subsalicylate lacks reports of adverse fetal outcomes; however salicylates may cause congenital defects, increased perinatal mortality from ductus arteriosus in utero, intrauterine growth restriction, and salicylate intoxication.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D and X are being phased out.

Although the risk for toxicity may be small, significant fetal adverse effects have resulted from chronic exposure to salicylates Because of this, the use of bismuth subsalicyate during gestation should be restricted to the first half of pregnancy and then only in amounts that do not exceed the recommended doses 3).

Pepto Bismol Breastfeeding Warnings

Use is NOT recommended.

Excreted into human milk: Yes

The excretion of large amounts of bismuth obtained from bismuth subsalicylate into breast milk is not expected because of the poor absorption of bismuth into the systemic circulation. Salicylates, however, are excreted in milk and are eliminated more slowly from milk than from plasma with milk:plasma ratios, rising from 0.03-0.08 at 3 hours to 0.34 at 12 hours 4). Due to the potential for adverse effects in the nursing infant, the American Academy of Pediatrics recommends that salicylates should be used cautiously during breast feeding. A recent review also states that bismuth subsalicylate should be avoided during lactation because of systemic salicylate absorption.

Comments:

  • Bismuth is not expected to appear in high concentrations in breast milk due to poor systemic absorption.
  • Salicylates are excreted in breast milk.

What does Pepto Bismol do

Nervous system

  • Rare (less than 0.1%): Myoclonic encephalopathy
  • Frequency not reported: Weakness, fatigue, depression, anxiety, irritability, insomnia, unsteady gait, motor incoordination, loss of memory, jerky movements, mental confusion, disorientation, difficulty in walking and speaking, tremor, myoclonic jerks, incontinence

Nervous system toxicity is a common feature of bismuth toxicity. Bismuth toxicity is characterized by the insidious onset of weakness and fatigue, depression, anxiety, irritability, insomnia, unsteady gait, motor incoordination, loss of memory, and jerky movements. Acute toxicity may result in the development of mental confusion, disorientation, difficulty in walking and speaking, tremor, myoclonic jerks, and incontinence.

Myoclonic encephalopathy has occurred in patients who have ingested bismuth for several months to years, but the incidence is very rare. Recovery of patients from bismuth encephalopathy may take several months following discontinuation of use. Bismuth encephalopathy has generally been reported in patients ingesting salts other than subsalicylate.

Other

Salicylism has been reported in patients who chronically ingest bismuth subsalicylate (the active ingredient contained in Pepto-Bismol). Common complaints include vertigo, diminished hearing, lethargy, CNS (central nervous system) dysfunction, confusion, tinnitus, vomiting, and abdominal pain. Patients may present with respiratory alkalosis and metabolic acidosis, azotemia, and hypoprothrombinemia and platelet dysfunction. The elderly may be particularly vulnerable to the development of salicylism.

Frequency not reported: Salicylism

Gastrointestinal

  • Very common (10% or more): Black stool
  • Common (1% to 10%): Black tongue
  • Frequency not reported: Nausea, vomiting

Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.

Some side effects can be serious.

If you experience this symptom, stop taking this medication and call your doctor immediately:

  • ringing or buzzing in your ear(s)
  • diarrhea lasting longer than 2 days
  • worsened stomach symptoms.

Pepto Bismol (bismuth subsalicylate) may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.

Human Toxicity Reports

Six examples of poisoning by bismuth subsalicylate were reported 5) arising from treatment of syphilis involving the simultaneous occurrence of stomatitis and albuminuria. The study author noted that bismuth tended to be mobilized during acidosis and advised caution in administration of bismuth to patients subject to acidosis 6).

A case was described in which encephalopathy occurred in a 60 year old man that was attributed to use of  bismuth subsalicylate for diarrhea 7). The diagnosis was supported by an electroencephalogram and a blood bismuth level of 72 uG/L. The patient recovered completely within one month after the drug was discontinued 8).

Inorganic bismuth salts, formed from metabolism of bismuth subsalicylate in the gastrointestinal tract, apparently present little or no risk to the fetus from normal therapeutic doses, but the data available for bismuth in pregnancy are poor, and the actual fetal risk cannot be determined 9). On the other hand, the potential actions of salicylate on the fetus are complex. Although the risk for toxicity may be small, significant fetal adverse effects have resulted from chronic exposure to salicylates. Because of this, the use of bismuth subsalicyate during gestation should be restricted to the first half of pregnancy and then only in amounts that do not exceed the recommended doses 10).

Bioavailability of doxycycline was significantly reduced by 37% and 51% respectively, when bismuth subsalicylate was given simultaneously and as a multiple dose regimen before doxycycline. Bismuth subsalicylate should not be taken when doxycycline is used for therapeutic purposes. The study authors suggest travelers should not take these agents together to prevent diarrhea 11).

Pepto Bismol overdose

In case of Pepto Bismol overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can’t be awakened, immediately call your emergency services number.

Moderately toxic and probable oral lethal dose in human is 500mg to 5,000mg per kg body weight for a 70 kg (150 lb) person 12).

If you think that you or anyone else may have taken a Pepto Bismol overdose, get emergency help at once. Taking an overdose of Pepto Bismol (bismuth subsalicylate) may cause unconsciousness or death. Signs of overdose include convulsions (seizures), hearing loss, confusion, ringing or buzzing in the ears, severe drowsiness or tiredness, severe excitement or nervousness, and fast or deep breathing.
