I am a 74 yr old male with MG. Prednisone (high dosages) elimate most MG symptoms (especially eyes), but of course is slowly killing me probably! We tried Rystiggo and it lengthened the time between eye issues. We then tried IVIG (twice) and it gave me severe headaches and made me feel lethargic both times. Now we are going to try IMAAVY. anyone had any experience with it yet?
