It seems the main differences are that it is a subcutaneous
injection and thus not deep, and that it is used approximately half as often as
Avonex. Will they drop Avonex?
So now I'm wondering if anyone here has used Plegridy, and if so, how things are working. I'm now back on Tecfidera (another Biogen product) after a false start, hoping to avoid nasty digestive side effects by greatly increasing time between the 120 and 240 mg doses (per my neuro).
