My GI said the same thing--that if Remicade hasn't worked in 3 infusions, then it probably won't at all. However, I was able to achieve remission with 5 infusions and the right combo of rectal meds. Don't lose hope yet!
He could take Remicade and Imuran at the same time and see if that helps, but I personally wouldn't want to be on two immunosuppressing medications at the same time. Or maybe he could take a few infusions of Remicade and then wean off to the Imuran only. Otherwise, the only things (in the traditional medcial realm) left are Humira, which is still in clinical trials, or surgery.
