If youre on predisone and not having symptoms i would try to taper of it as fast as possible because you will build a resistance the longer you are on it. It works great for me during a flare about 1 or 2 times a year, if i use it more than that then it doesnt work (even at 60 mg a day). After about 2 months of continued use it doesnt do much for me, I have to use it sparingly for it to work when i really need it.
I'd say he should follow his doctors or get another doctors opinion.
