I'm having to wait until October before I begin my switch from Rebif to Tysabri. My neurologist says that he recommends this for PRMS (I've since moved to Cleveland, OH, from Dallas since my initial diagnosis of MS). I don't know how Tysabri affects RRMS.
RX, good link. Thanx.
Tysabri has been recommended for "relapsing" forms, so it can be used for RRMS. However, prescription guidelines, and I imagine insurance guidelines, say you must have failed on the current disease modifying drugs...at least that is how they're starting the reintroduction.
I do fine on Betaseron, so I know I wouldn't qualify.
Best of luck to you. I've heard some amazing things from folks who took Tysabri during the trials.
