Patricia, I'm not sure why he chose that corticosteroid as opposed to one more widely use, like Pred. He was, like most neuros, NOT an expert in MG. Well, at least he didn't kill me, though I never did recover my pre-crisis strength and stamina. Plus I've had breathing problems ever since the crisis, something I didn't have before. One thing in his favor is that he accepted the diagnosis of MG, without thinking he had to re-diagnose me, like so many other neuros do. It's as if not a one of them can accept the diagnosis of another.
Hugs,
