Multiple Sclerosis
"I&#039;ve been on tysabri since January 2008 and have not had any flair ups. It&#039;s even better that they can now test for the virus that causes the rare brain infection, which I don&#039;t carry. Benefit I like is its done every 28days so I don&#039;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&#039;m on social security disability and after Medicare&#039;s payments I&#039;m left with a bill for medicine and infusion of close to $1200 every 28days."
