My neuro-opthamologist put me on 80mg of Prednisone. When my vision returned we tapered off. I have since gotten Prednisone 60mg to try to get my MG under control. After being on that dose for a while it was killing the muscles in my legs. Reached a point I almost had to get a wheelchair. I'm down to 20mg and doing pretty good. We are still tapering. Cutting 2 1/2 mg every 3 months. I didn't drive for one year due to double vision.
