You are already aware of your dignosis of ulcerative colitis
is an established drug to treat the condition
and keep you in remission. If this has not been helpful, I
would try different drugs such as mesalamine (Asacol,Pentasa,Lialda,
Apriso etc,). Corticosteriods on a short term basis to acheive remission
is O.K. but not for maintenance, Immunomodulators like Azathioprine
may be needed. Also Infliximab that
is used to treat Crohn's is also effective in ulcerative colitis control
and other similar drugs.
Wish you good health.
