I just had my 80th treatment of tysabri, not 1 relapse. My JC blood work came back positive so my doc wants me to switch to Tecfidera. I don't know what to do. Tysabri has worked so well, but now I am scared of PML , but also scared tecfidera won't work and scared of the side effects.
Has anyone had to switch? Can anyone give me any advice?
