Hi, I have a question regarding Prevacid. I started taking 2 a day on August 1, and right away started developing stomach pain and messed about bowel. By this past weekend, I had diarrhea so bad I could not leave the house. Say my gastroenterologist yesterday, he said to stop the Prevacid and that maybe it was too much for me. I still have diarrhea after stopping for 2 days, when can I expect to feel normal? I still have stomach and back pain. Thank you.
