It's hard to say but, if fistulas are the issue, Remicade has more cases to support how it can help with fistulizing CD.
I was on Remicade for a while but developed an allergy to it over time. While it seemed mild (mild skin blotchiness near the end of each infusion, some throat itchiness), my doc had me discontinue. I tried Cimzia after that and am now on Humira (although I was off for two months due to advancement flap surgery and concerns with healing).
So far none of them have worked for my main symptom (fistulas) but I'm hopefully the surgery/med combo will ultimately do the trick.
Best of luck!
