Tysabri
"I've been on tysabri since January 2008 and have not had any flair ups. It's even better that they can now test for the virus that causes the rare brain infection, which I don't carry. Benefit I like is its done every 28days so I don't worry about missing a dose or giving myself a shot. It usually takes about 3hours for the infusion. Only negative about tysabri is the cost. I'm on social security disability and after Medicare's payments I'm left with a bill for medicine and infusion of close to $1200 every 28days."
