Prednisone
"Female (23) I was diegnosed with UC in 2008 at age 15. Got horrible abdominal pain, I'd roll up in a ball n just cry, frequent bathroom trips, blood clots and dropped down to 100 pounds. I tried several medications none of them worked except prednizone.  I agree side affects are horribly I've had different reactions all 3 times I been put on them feeling wired not sleeping till 6am looking like a chip munk, broke out in itchy bumps on my chest jaw line and back, joint pains BUT as others said it did stop my inflammation  immediately. After that I was put on azithiroprine and has been the only medication that has controlled my UC thank goodness . Don't let UC control you. You control UC! Always be srtong and very open minded about your disease "
