A member asked:

Had stomach pains for few days, stool is really dark, i know that could mean upper gastro tract bleeding but i also took pepto bismal, should i worry?

A doctor has provided 1 answer

No: Pepto bismol (bismuth subsalicylate) can cause tarry stools. If the tarry stools occurred after you took it, there is no issue.
