multiple sclerosis
"I am 24 years old and have been on Tysabri for about a year, after Rebif did not work for me. I have zero symptoms while on Tysabri. Infusion is easy and only once a month, and I went LESION FREE while on it! The ONLY reason it's not a 10 is because of the black box label for PML. This was such a stresser for me even though I was JC negative...until now. I am going off of it because I am now positive and will be switching to a new medicine, which I'm still debating on. Overall I say if you're JC negative, it is an amazing medicine."
