Pepto-Bismol (also known as the “pink stuff”) is a medication that is commonly used to treat diarrhea and upset stomach. It is available over the counter as an oral liquid, capsules, and chewable tablets. Pepto-Bismol usually works within 30 to 60 minutes.

What is Pepto-Bismol used for?

The active ingredient in Pepto-Bismol, bismuth subsalicylate, works to relieve upset stomach and is also an antidiarrheal. Pepto-Bismol can be taken for the following stomach problems:

  • Traveler’s diarrhea
  • Diarrhea
  • Heartburn
  • Indigestion
  • Nausea
  • Gas
  • Burping
  • Fullness

How often can you take Pepto-Bismol?

Adults and children 12 years and older can take one dose of Pepto-Bismol every 30 to 60 minutes until symptoms improve. Do not take more than 8 doses in 24 hours, and do not take Pepto-Bismol for more than 2 days to treat your symptoms without consulting your doctor.

Make sure to read the instructions on the packaging, since Pepto-Bismol comes as a liquid, capsules, and chewable tablets. This means the amount you need to take for each dose varies.

Pepto-Bismol may not be the best option for everyone. It is not recommended for the following situations:

  • People with an active stomach ulcer, a bleeding problem, or who have bloody or black stools
  • Children or teens who are recovering from chickenpox or flu-like symptoms because of the risk of a serious illness called Reye’s syndrome
  • Pregnant women

Additionally, if you have a fever or mucus in your stool, ask your doctor before using Pepto-Bismol.

There is controversy about whether you should routinely take probiotics with antibiotics and the question cannot be answered with a straight yes or no. Evidence for taking probiotics with antibiotics includes a Cochrane review which reported that children who were given a course of probiotics after antibiotics had less diarrhea. Evidence against taking probiotics with antibiotics includes a 2019 Italian study that reported that the gut microbiome of people given probiotics after antibiotics took six months to return to its normal state compared to only three weeks for those not given any probiotics. More studies are needed before a definite statement can be made. Continue reading
