Budesonide
"This medication was an answer to prayer. I suffered with chronic diarrhea for over a year and had tried Imodium, dietary changes, and anything else I could think of to stop it. I eventually had a colonoscopy and biopsies taken showed collagenous colitis, a form of microscopic colitis. ONE day on this med stopped my diarrhea. I haven't had any negative side effects whatsoever."
