Last week I had a colonoscopy which revealed microscopic colitis. I have had watery diarrhea for the last 3 months. I have an appointment to see the gastroenterologist in one month. Is it safe to take Pepto Bismol 1-2 times daily until I see the doctor? My current medications include: levothyroxine, dexilant, metoprolol, simvastatin, low dose ASA, cymbalta, fish oil, osteobiflex, Ca with VD, and a MVI. Would any of these cause diarrhea? Metoprolol, cymbalta and simvastatin are relatively new (4 months). Also, if I'm taking Pepto Bismol should I continue taking the low dose ASA? Thank you. Paula.
