I spoke to George at Biogen a few days ago and he said it takes about six months for disease activity to resume in what they've seen for people who have stopped Tysabri.

My MS neuro said that we could take a break from Tysabri if we wanted to but that there was no indication that it has any benefit to do so. He said that other neurologists around the country have been suggesting it and if we wanted to, we could, he was just letting us know (those of us in the infusion room).

Two of my infusion roomies have been on Tysabri since the beginning of the Antegren trials, so way longer than me.

I hope that answers your questions too Leggz. I get my 32nd infusion next Friday.
