Just curious as to why you would want to take this twice a week vs. taking Rebif 3x a week. You are getting approx 3.5x the dose with Rebif for approximately the same cost.
I've been on Avonex for a little over 4 years now. Early in my experience with Avonex, I was contacted regularly via phone by the "Avonex Nurse." I don't know if the information she provided is completely unbiased but she did state that the absorption efficiency from a subcutaneous injection is about 40% while that from a intramuscular injection is around 80%. If this information is correct, and it would be great if someone could corroborate here, then I feel that it's important to take it into account when comparing dosage regimens between different medications.
By the way, I was wondering if there have been any trials with a 2/week 30µg IM dosage?
