I lost response to Remicade, so I'm on Cimzia now. I think it's helping, but sometimes it's hard to tell. I'm not in remission, but I am off of oral steroids for a couple weeks now.
I do not have any bad side effects from the Cimzia other than a bruise at the injection site. (It turns a funny whitish color for a couple days.) But, that's not troublesome or painful in any way. In fact, I just had my shots this morning and it's just another day.
Good luck with your decision!
