Tysabri?

Hi everyone:
I usually post in the Crohn's group, but thought I would post in the MS group. I have severe Crohn's Colitis. Long story short, I have exhausted all meds and I am scheduled for my first Tysabri infusion on Tuesday. I did take the PML blood test and it came back negative. I am still terrified to try this drug due to the PML. Does anyone in this group use it for MS? Nobody in the Crohn's or Ulcerative Colitis groups seem to use it ... too scared. Or at least it is never mentioned there. I just wanted to get your perspective on Tysabri because I know it is heavily used for MS.
Thanks for your input and good luck to everyone! Thanks, Debbie

Thank you Gretchen1. I just checked it out. Very helpful!

 i am on tysabri for 2 years now and i have tested positive for the jc virus...after long thought i am going to stay on it until another oral med.is fda approved..the tysabri has helped so much....i have been out of the hospital for 2 years now..the mri's have been very good as well...there is a plan incase pml would strike...but for me going off tysabri the flareups would more than likely have the same results...so as long as they monitor you i think and it is just my opinion everything will be ok..barb

the tyasbri has worked well for me...my doc. and i have decided to stay on it until a new pill gets fda approved..of course i cant remember the name of it but like he says it will change many times before it comes out....the risk with tysabri is worth it for me..without it i would be in worse shape so i am ok with the risks..they do extra mri's and keep a watch for any problems..i put off taking it until i had no choice but to go on it and now i wish i had done it sooner...barb
