I have JUST started Tecfidera,
and I too am a bit creeped out by the tales of
PML, (
and I was not tested for JC, but I guess they aren't doing that just yet with Tec.)but I will be insisting (if necessary) that I be monitored to MY satisfaction, and will switch to something else if it doesn't work, or my numbers go too low, or if I just am no longer comfortable with how close I am to a limit.
