Hi, I'm sorry, but I can't help with your question, as I've never taken Copaxone. I'm on Rebif now, but started therapy with Avonex several years ago. When I first started the Avonex, the warning was that you could get "flu'like" symptoms, with fever and chills, but that they would get better in time. With the first injection, I had them all, but the reassurance about getting better in time was on the mark, so I hope that the same is true for you.
