I am taking Lansoprazole for acid reflux and indigestion, I would like to know the side effects from taking this medication. I have been having diarrhea that is watery for the past week, even if i drink water i get the diarrhea,it seems that i can t eat or drink anything. I can t control the diarrhea, have to be near a bathroom all the time. Just wondering if it is the meds., This is all the meds that i am taking.
