Folks, Avonex is a 'WONDER DRUG' for some, and absolute hell for others. I'm one of those 'others'. I used it for 14 months then, literally, threw it at my doctor and told him to use it and get back to ME on how he felt! You name it, I had it in the side effect department, including losing most of my hair. Yep... now there's one they don't admit to too readily, but it DOES happen and it IS from the meds.
Best of luck to those on it. Hopefully, none of you will experience my issues with it.
