I was on Remicade for almost a year and I decided to quit because I was having a lot of the same things you are experiencing- weight gain, infections in my piercings (which closed up completely), and also hair loss and some serious acne. My doctor did not support me in quitting and didn't think that my symptoms had anything to do with the Remicade. However... all of those things went away without the drug! Now I'm in a tough spot, though, because I'm flaring and I don't want to go back on biologics (even though they worked very well for my Crohns). It's something to think carefully about
.... is it worth the side effects to feel better? Or, if you're like me, maybe the side effects are bad enough that you're willing to risk flaring again. It's even tougher without your doctor's support. Good luck in your decision making!
