Lemtrada was the first drug my neuro wanted to put me on. My MS is aggressive. I declined it because we didn't have insurance that would cover it and would have to pay out of pocket. I'm actually doing well on Tysabri but I'm JCV+ and I know it's not something I'm comfortable with staying on more than 2 years (maybe less depending on how my titres rise). I have researched Lemtrada a LOT and it's the medication for me (obviously my neurologist agrees). So we are paying out of pocket and the drug company (Genzyme) is helping too.
