I also takes Cellcept (500mg x2, am and pm) since 8/21, plus prednisone (started at 10 mg/day, now at 75 ) and 5 x 60 mg Mestinon + 1 delayed 180mg. After 2.5 months , the only improvements are the drooping of one eye-lid and the double vision which disappeared, swallowing and chewing difficulties, plus arm muscle weakness are still present.
I also had two IVIg cures with very little effect.
Besides this, I do not appear to have any significant side-effect (yet?)
If the situation is still the same at the end of the month, my neurologist would like to try plasmapheresis but I'm not very keen for it, if they have to be repeated monthly or so…
