I cannnot take 5ASA's either.
Imuran did not help me much
I was then to go on remicade, then humira (if I could get on a study or approved).
Between Imuran and Remicade I got put on Cellcept for my kidneys and it can also help a small portion of UC patients. I am in remission w/that and 7.5 mg of pred.
