I took Pepto-Bismol on Tuesday morning at 5:15am, around 11am and around 7pm. Today, I had a black stool. Is this normal?

I've been on a trip to Mexico since Tuesday. I have never had a saddle like this one.

Good evening ma'am,

Yes, this is normal. This is a side effect of Pepto-Bismol™.

This is nothing to worry about. If you have not taken Pepto-Bismol™ since Tuesday night, your stool should return to its normal appearance by Friday morning.

If not, I would advise you to go see a doctor.

Good evening,

Alexandre Chagnon, pharmacist
