Dr, My mom is receivig Asacol (mesalamine)tab. For ulcerative colitis, is there any alternative treatment? With minimal side effects? Or suppository?

There is. but suppositories are useful only in Ulcerative Proctitis (lower rectum) Treatment for UC and , in fact, all inflammatory bowel disease has advanced a good deal since ASACOL! Your Mom should speak with her GI Doc! Hope this helps! Dr Z.
