multiple sclerosis
"I failed Copaxone and then Avonex therapy. I started Tysabri in March of 2010. Some improvement in my disability. The only side effect that I get is a two day migraine post infusion. Otherwise, I do NOT miss the shots and flu symptoms. I actually look forward to the 2 hour nap during and after infusion! I recommend this medicine to those that fail on the other ABCs!"
