I have received 6 infusions over the months and although it had helped a little, not until I had a severe flare and went on a 5 day Prednisone script did I reach "remission".
We're talking a good 20+ years and after the Prednisone my GI suggested Entocort which has fewer side effects than Prednisone since it dissolves in the bowels and not in the stomach.
I do not want to quit the Remicade, it is hard to get back on it once you quit, so I look at as "what isn't broken - don't fix". Obviously, the Remicade and Entocort are what it takes for me and I would hate to quite Remicade to find the Entocort doesn't work as well alone.
Try mentioning a maintenance med with the infusions with your GI.
