I had a mom (nursing 5 month old) call today to say that she had been nauseated with some vomiting & diarrhea for a week. She has taken Immodium (I hope I can name names here), but stated that it seemed to make her more nauseated and did not stop the diarrhea. Her doctor's office staff recommended that she try Pepto-Bismol, so she called me to ask if it's compatible with nursing. My first response was "yes," but I told her that I would check and get back with her. I called our handy pregnancy risk line/breastfeeding folks and was told that theoretically, bismol is similar to aspirin. So... "in theory" there may be a concern with Reyes syndrome. I was informed that while there probably would be no problem, it was perhaps not wise to recommend Pepto-Bismol. Any comments from our pharmacists on this? I was surprized!
