I have been on it for over a year. It's no miracle drug but it has stabilized me some. No side effects like Imuran. Are you on prednisone? If so how much? When I was on 60mg I almost had to order a wheelchair due to my legs. My neuro-muscular Dr said it was the prednisone. I'm now down to 12 1/2mg and legs are a lot better. As for how long for the Cellcept takes, it is 6-12 months.
