Hi Kathie,
Your last post confirms that the neuro you have been seeing is not an MG expert: start steroids, wean off and THEN start an immunosuppressant is a bizare prescription. You should know that immunosuppressants may take quite a long time to act, some for several months or maybe a year. That´s why usually steroids AND immunosuppressants have both to be taken for quite a period of time to give a chance to the immunosuppressant to kick in and only after that, start tapering...
I think you´ll be in better hands with Dr Drachman.
Maurice.
