Multi-symptom Pepto-Bismol contains bismuth subsalicylate and is the only leading OTC stomach remedy clinically proven effective for both upper and lower GI symptoms. Pepto-Bismol is in more households than any other stomach remedy, making it a convenient recommendation with a name your patients will know. It has been clinically-proven in double-blind placebo-controlled trials for relief of upset stomach symptoms and diarrhea.

Each tablespoonful (15 ml) of Maximum Strength Pepto-Bismol Liquid contains 525 mg bismuth subsalicylate (236 mg non-aspirin salicylate). Maximum Strength Pepto-Bismol Liquid contains no sugar and is low in sodium (less than 5 mg/tablespoonful). Inactive ingredients include: benzoic acid, D&C Red No. 22, D&C Red No. 28, flavor, magnesium aluminum silicate, methylcellulose, saccharin sodium, salicylic acid, sodium salicylate, sorbic acid and water.


Maximum Strength Pepto-Bismol soothes upset stomach and indigestion without constipating; controls diarrhea within 24 hours, relieving associated abdominal cramps; and relieves heartburn and nausea.


For upset stomach symptoms (i.e. indigestion, heartburn, nausea and fullness caused by over-indulgence), the active ingredient is believed to work via a topical effect on the stomach mucosa. For diarrhea, it is believed to work by several mechanisms in the gastrointestinal tract, including: 1) normalizing fluid movement via an antisecretory mechanism, 2) binding bacterial toxins, and 3) antimicrobial activity.

Children and teenagers who have or are recovering from chicken pox or flu should not use this medicine to treat nausea or vomiting. If nausea or vomiting is present, patients are advised to consult a doctor because this could be an early sign of Reye syndrome, a rare but serious illness.
