Hey DOcTorT, people take Benadryl in case they may have an allergic reaction to Tysabri. I got my 60th infusion last Fri. I was sitting next to a gal who was scratching her arms, about 10 minutes after I noticed the nurse came with a shot of Benadryl for her.

My thoughts on your last post. Tysabri has been my friend, restored my QOL.
In the first 12 months of Ty there has been 1 case of pml, up to 24 months a few cases. The odds of pml between 2-3 yrs is the highest but, in my opinion still rare. I know what ms can do to me so, I chose to stay on Tysabri.

Good luck and best wishes,
Linda
