Ricardo,
I was diagnosed with MG at 16 years old. Had 2 thymectomys One when I was first diagnosed and the other when I was 18. I have been on Imuran or (Azathioprine) for at least ten years or more as well as Prednisone since my diagnosis. At one point I was off Prednisone for about a year but kept getting bronchitis and had to restart it and im still on it now (2 yrs later). 20mg daily. It hasnt been easy trying to get off this stuff or even lower it cause my body notices the drop and its only like 2 milligrams each time Have a portacath in my chest for IVIG treatments I get every 3 weeks. Mestinon 60mg every 3 hrs and still no remission for me but I really havent had any issues with the meds other than gaining weight with Prednisone.
