Can Pepto Bismol cause maroon coloured stool? I've had some very dark stool this afternoon and into the evening with a maroonish tinge to it. I'm a bit concerned because other than the Pepto Bismol, I haven't eaten anything that might have caused this. I do have a bit of gas but otherwise feeling okay.
Ironically I just saw my GP a couple of weeks ago for my annual physical. I had bloodwork done at that time. The office hasn't called me so I assume everything was fine. I do have a referral to a new GI but it's going to be a few months before I can get an appointment with him, so I don't really have anyone I can contact right now.
