Not recommended: Let me be transparent: I no longer use Avonex (interferon beta 1a) for ANY of my numerous MS patients, as it is the least effective medication of all on the market, and has been shown to be inferior on 4 head to head studies. Side effects of interferons include, injection site reactions, flu reactions, liver toxicity, depression, fatigue, thyroid problems. Find a neurologist who specializes in MS.
