HI there. One more answer: yes, Avonex and Rebif are the exact same interferon...however, Rebif is stronger simply due to the amount you are getting, and how often you get it. While Avonex is given intramuscularly 1 time a week, Rebif is given subcutaneously 3 times a week..
The whole reason Rebif was introduced was because so many patients complained of feeling like they were craving the drug...as in, after 4-5 days they honestly felt that it wasnt working and they needed a shot..
Because Rebif is given 3 times a week (i do mine T-Th and Sun taking off Fridays and Saturdays) you never feel that "i need a shot feeling". I happen to think Rebif is great! And, no, you will not have any changes at all in the way you react to it, at least not in a negative side effect kind of way..the drug is the exact same formula...youre already used to Avonex, you wont have a problem changing.
Hope this helps.
