All drugs have side effects. I got dry eye while taking prednisone, and since starting Vyvgart, it has gotten worse. Hoping it is over in September, as the doctor said the cellcept would be working by then. I found I am allergic to the Vyvgart, so they give me 50 mg of steroids with each treatment, which my nurse said is a type of prednisone. Can't win with these awful meds.
