Tysabri Blogs Itself

Hey out there--what's the Newest? I found out that while on Tysabri, you may develop "Persistently Positive Antibodies". In this case, Tysabri will stop working for you. These "antibodies are proteins made by the body to help fight against foreign invaders" -- your body thinks Tysabri is a Foreign Invader (like bacteria & viruses). This info. is NOT in the Patient Medication Guide, that you get before every monthly infusion. This info. is in a booklet called "Getting Started with Tysabri" that Biogen mailed to me, not knowing I've already been on Tysabri for many months. Why doesn't Biogen include this info. in the Patient Medication Guide, which has been the SAME since I started receiving it almost a year ago-? Oh, well, I guess you can call it one more of the persistent OVERSIGHTS that Biogen is guilty of.
