Hi Frank,
I was on Avonex for 18 months. It's an intramuscular shot but only once a week. Once you get used to the harpoon it's not too bad. I had flu-like symptoms for one day a week and they weren't usually too bad. It's a much lower dose than the other interferons.
The good thing is you only have to think about it once a week.
Hugs to you and Deb.
