gerd
"I was prescribed dexilant for a possible ulcer which caused nausea. It may have helped the nausea a little but not much.  After taking it for a few months, I got severe diarrhea and cramping.  I was not able to leave my apartment or go to work - the diarrhea was uncontrollable.  I have never had diarrhea this bad before.  I realized it was probably dexilant causing the diarrhea and cramping today after searching on the Internet for side effects.  I doubt it is anything other than the dexilant.  Hopefully the diarrhea and cramping will subside fairly quickly."
