I Accidentally Took Pepto Bismol While Breastfeeding

Worried because you took Pepto-Bismol while breastfeeding? Don’t panic—one accidental dose is very unlikely to harm your baby. Still, Pepto isn’t recommended for nursing moms since it contains salicylates (similar to aspirin) that can pass into breast milk.

Here’s What You Need to Know

First off—don’t panic. Lots of moms have been in your shoes, and one accidental dose is very unlikely to hurt your baby.

Why doctors say “no” to Pepto while nursing

• Pepto-Bismol has bismuth subsalicylate (a cousin of aspirin). Salicylates can slip into breast milk, and there’s a tiny worry about Reye’s syndrome in kids.
• Because of that risk—even though it’s small—most health sites and doctors say to avoid Pepto while breastfeeding.

If you already took it

• One dose? Don’t stress. The amount that could reach your baby is extremely low.
• You can keep breastfeeding as normal.
• Just keep an eye out for anything unusual in your baby—like extra sleepiness, vomiting, or irritability (rare, but worth watching).

What you can use instead

• For heartburn or indigestion: TUMS, Gaviscon, or Maalox are usually safe.
• For diarrhea: Imodium (loperamide) is generally fine for nursing moms.
• Natural soothers: ginger or peppermint tea, or the BRAT diet (bananas, rice, applesauce, toast).

Bottom line

If you accidentally took Pepto while breastfeeding, your baby will most likely be just fine. It’s just not something to keep using while nursing. Next time, stick to the safer options above—and if you’re unsure, call your doctor for peace of mind.
