I hesitate to post on this subject, as some people do take this drug and if it is working for them then I for one do not want to pour cold water on their experience, but I also think it is important to have facts to hand and be aware of the dangers.
I get regular updates about the numbers of people who have been unlucky enough to contract PML and those who have died from it.
The latest message is as follows:
Bad news:
As of September 5, 2012, there have been 285 confirmed cases of PML worldwide (102 in the US). 62 of 285 (22%) of the patients with PML have died.
Until today approximately 104,300 patients have received TYSABRI in the postmarketing setting worldwide.
