I am sufferings from ulcerative colitis since 2000. Doctors put me on 'Defcort 30' and asked to reduce gradually along with 'Mesacol. Now i am not having any blood with stool. Still i am not able to give up Defcort as whenever i reduce it gradually upto 1.5 mg a day, again my stomach gets upset and i again and again have to go to toilet just to release gas only that too with swear pain. Pl suggest some medicine as also i am getting tired very often. Also i feel my stomach every time heavy.
