m sure, but there it is, lol)
I think in terms of
Avonex, because it is an IM
injection, you will need a little bit longer of a needle because the needle needs to go into the muscle, so you probably don't have much of a choice in length. If it were a sub-q injection, like Rebif, you can get away with a much smaller needle, both in length and width.
TMI probably but now you'll all know, lol.
