How does Pepto Bismol work?
Pepto Bismol protects our stomach in the following ways:
- The main ingredient of Pepto Bismol is bismuth subsalicylate. It wraps stomach ulcers and protects them from stomach acids.
- Bismuth subsalicylate kills Helicobacter pylori, a bacteria that is the main cause of stomach and small intestine infections and can cause ulcers. However, doctors prescribe Pepto Bismol with other antibiotics for better results.
- It is an antacid and protects our stomach cells during acid reflux.
Pepto Bismol also treats diarrhea by:
- Increasing the amount of fluid absorbed by GIT mucosa.
- Coating the GIT tissues to slow down the passage of liquids from GIT mucosa to stools.
- Reducing the inflammation of the stomach and intestine by preventing the release of prostaglandins, a chemical that causes inflammation.
- Reducing the over-activity of the stomach and intestines.
Side effects of Pepto Bismol
Side effects of Pepto Bismol usage are temporary and go away over time. However, expired Pepto Bismol side effects can be a bit longer-lasting. Pepto Bismol side effects are as follows:
- Black tongue and stools. Our saliva and GIT contain small amounts of sulfur and when bismuth subsalicylate comes in contact with this sulfur, it converts bismuth subsalicylate to bismuth sulfate. Bismuth sulfate is black so turns the tongue and stools black.
- Constipation. Bismuth subsalicylate reduces the flow of water in stools so it may result in the hardening of stools. Expired Pepto Bismol can sometimes worsen this side effect.
- Salicylism. It is a condition that results from ingesting salicylates for a very long time. Symptoms include vertigo, reduced hearing, abdominal pain, vomiting, and lethargy.
Who should not take Pepto Bismol?
Before taking any medicine, one should read the labels written on the packages. It is advised that some people with specific conditions should not take Pepto Bismol and these people include:
- People who are allergic to salicylates or aspirin because the main ingredient of Pepto Bismol is bismuth subsalicylate.
- Children and teenagers who have flu symptoms or suffering from chickenpox.
- People who are already taking some drugs like anticoagulants, anti-seizure drugs, diabetes and gout medicines, NSAIDs (non-steroidal anti-inflammatory drugs), or tetracycline antibiotics.
- Mothers who are breastfeeding.

Tightly closed liquid containers
Pepto Bismol comes in both tablet and liquid forms. Most people ask what happens if you drink expired Pepto Bismol. It is not the expiry date that can cause much trouble but the contamination.
The liquid containers are more susceptible to germs than Pepto Bismol medicines. This is because after taking one dose, we forgot to close the bottles tightly.

Is it ok to take expired anti-diarrhea medicine?
Different medicines behave differently after expiration. Some medicines lose their effectiveness rapidly after expiration but some medicines maintain their effectiveness even after many years.
For example, Imodium is not recommended after expiry because it loses its effectiveness sometimes after its expiry but the anti-diarrheal medicines like Tums and Pepto Bismol still retain some of the effectiveness.
