Welcome!
Remicade in combination with Imuran worked awesome for me. Really decreased my symptoms (not remission but close) and the only side effect I saw was some fatigue
I am curious though, your signature says you are on Simponi, any idea why your gi would choose that? I have heard good things but it is a newer med, often doc like to try older mess they have more experience with.
On that note Remicade and Simponi target the same protein TNFa. That means there is a smaller likelyhood if Simponi didn't work for you then Remicade also won't. Not for sure just a slightly decreased chance. Entyvio is a different mechanism of action.
