Generic Name: bismuth subsalicylate (BIZ-muth sub-sa-LIS-a-late)
Brand Name: Examples include Kaopectate and Pepto-Bismol
Pepto-Bismol is used for:
Treating heartburn, upset stomach, indigestion, nausea, diarrhea, or symptoms associated with eating or drinking too much. It may be used to decrease the number of bowel movements and make the stool firmer. It may also be used to treat other conditions as determined by your doctor.
Pepto-Bismol is a salicylate. The way that it works is not fully understood. It is thought to limit secretions in the digestive tract, reduce inflammation in the stomach and intestines, and inhibit the growth of certain bacteria and viruses that can cause intestinal tract diseases.
Do NOT use Pepto-Bismol if:
- you are allergic to any ingredient in Pepto-Bismol

- you have bleeding problems (eg, hemophilia), active bleeding ulcer, black or bloody stools, or Von Willebrand disease
- you are taking another salicylate medicine (eg, aspirin)
Contact your doctor or health care provider right away if any of these apply to you.
