Can You Take Pepto Bismol While Breastfeeding? Safety Tips

Knowing what food you can and can’t eat and what medications to avoid isn’t just something pregnant women are concerned about. Pregnant women are advised to avoid certain medications while they are still expecting but the rules can become more confusing for nursing moms.

With a lack of research and evidence to support the safety of certain medications while breastfeeding, many nursing mothers are left with warnings like ‘speak to your doctor before taking this medication‘ or ‘use with caution if nursing‘.

So, what is a breastfeeding mom to do if she is suffering from acid reflux, heartburn, diarrhea, or nausea?

When a person who isn’t nursing suffers from these symptoms they may simply reach for an antacid, but are medications like Pepto Bismol safe to use while breastfeeding? Can nursing moms take medication for heartburn and other common digestion issues?

What Is Pepto Bismol Used For?

Pepto Bismol is an over-the-counter antacid medication used to treat stomach problems like diarrhea and acid reflux. The active ingredient in Pepto-Bismol is called bismuth subsalicylate, which belongs to a drug family called salicylates.

Pepto Bismol can be taken in the form of a chewable tablet, a caplet, or a bright pink liquid.

People suffering from stomach problems can take either regular or maximum strength Pepto Bismol depending on their symptoms but must always follow the dosage instructions carefully.

Can You Take Pepto Bismol While Breastfeeding?

Nursing moms are not immune to stomach issues like constipation, nausea, and heartburn and there may be times when they want to take something to relieve their symptoms, but is Pepto Bismol safe for nursing moms?

There is currently no definitive clinical research that can provide strong evidence that Pepto Bismol is safe to take while breastfeeding. However, other drugs that fall into the salicylate category have been found to be harmful to nursing babies.

For example, research into Aspirin (another salicylate-based medication) has found that the drug can enter the breastmilk and have harmful effects on the breastfeeding baby’s health and development.

Whilst the research into Pepto Bismol and nursing is currently scarce, the knowledge on the safety of other salicylate drugs for breastfeeding moms is enough for the American Academy of Pediatrics to suggest using caution when taking Pepto Bismol and the National Institutes of Health to suggest finding an alternative to Pepto-Bismol altogether if you are nursing.

Is Pepto Bismol safe during breastfeeding? The clinical research is too thin on the ground to confidently answer either way.

As Pepto Bismol is in a similar drug family to Aspirin, a drug that has been found to be harmful to nursing babies, the best option would be to find an alternative treatment for stomach problems while nursing. 

Alternatives To Pepto Bismol While Breastfeeding.

Just because Pepto Bismol is best avoided while you are nursing, that doesn’t mean you have to suffer through your stomach problems and symptoms.

Speak to your doctor about what is safe to take for your symptoms while you are breastfeeding and they may be able to prescribe other drugs like Imodium for diarrhea and Omeprazole for heartburn or acid reflux.

There are many natural ways you can treat an upset stomach that won’t harm your nursing baby and will not interfere with the safety of your breastmilk.
