I am SO sorry to hear that! I liked Tysabri, too. Can you switch back? They took me off as Id been on it so long, and was having a bad reaction all of a sudden.

About 3 weeks

Only after about 4mos on TysabriI took myself off b/c I put my faith in God and tried for a child. I remember when I was on it I had no side effects only the usual metal taste n the mouth which is the same w/ Ocrevus. I am able to switch back. Just need to schedule my first infusion.

It took one month, I had my first infusion and in those 6mons I had two flare-ups I’m losing my hair in various places and I look like a chemo patient. I went on Ocrevus b/c it was convenient as far as time( every 6 mons) but if I knew it was going to DESTROY my body like it has I would have stayed on Tysabri. Everyone reacts different and I pray your infusion reactions are BETTER and more helpful than mine were.

Thanks! Hope it is going well for you. Love the cats!
