I never took benedryl or tylenol while on Cimzia (over a year in a clinical trial). And, I was one who had to take it on Remicade (and still had allergic reactions) so I was very nervous when I first got Cimzia. Also, I was told when the trial was ending that they would show me how to give myself the shot and I could have the medicine delivered to my home and do it myself. But, since I ended up switching to Humira (bad choice I think), I don't know if that was really true or not. But, I'd like to know for sure, as that is one of the things that will help me decide if I want to switch back or not.
