I have a very long history of symptoms like colitis. I had a colonoscopy six months ago and biopsies revealed collagenous colitis. I was prescribed budesonide for three months--reducing the amount every month until finished. It made a huge difference in my ?diarrhea-type episodes, consistency of BM's... I was thrilled. It has been about 2 1/2 months since I finished the budesonide. I still have the occasional "flares" which depend on what I eat but overall the urgency is much less. Changing doctors is what has helped the most.
