I just started on 9/3. Have my second infusion on Tuesday 9/17. I was posting updates from the first infusion as I thought I was seeing almost immediate results. However, more than likely this was from the Pred and the fact that I am so vulnerable to the placebo effect. Once the pred tapered down... bam... massive bleeding and pain again.
I just got back from the GI this morning who said that he was not surprised at all that I hadn't seen any results from it yet, that most of his patients don't until the 2nd/3rd infusion. Anyway... .don't know if he is just saying that to make me feel better or not but... we shall see.
As to the risks, there have been other people who posted, but they really are very small. Something like 2 in 10,000 get lymphoma without remicade. With... it goes up to 4. Add in 6mp or Imuran.. and it goes up to 7.
Of course, numbers don't matter much to you if you are one of the few unlucky ones.
