My GI also doesn't use remicade for short-term treatment. It can take three infusions before some people respond anyway, so it isn't that effective short term.
On a positive note, I had the three-infusion induction for Remicade about
four years ago, then had to stop because my insurance quit paying for it. After it was approved for UC, I started again and it worked beautifully. So it isn't true that it becomes ineffective for everyone.
In my case it's the whole array of drugs that works together to keep my UC in remission. If I try to taper either the Colazal or the Imuran, I'll start sliding toward a relapse, and those two weren't able to control the disease until the Remicade was added. I guess we're all just different and require individualized treatment.
Left-sided UC diagnosed 2001. Taking Colazal and Imuran, Remicade infusions and moving into remission. Finally off steroids after four years!
Now in remission for almost two years. Remicade has been my wonder drug.
