Like Erin, I think your doctor is jumping a bit ahead. There are lots of drugs out there to treat MG. The first line usually being mestinon. I took mestinon for 3 1/2 years before I had 2 crisis periods, and had 2 move to stronger meds. For some mestinon is all they need.
For the last 9 months, I have taken Imuran and some predisone. However, I'm now slowly cutting out the predisone.
I know Imuran has side effects, but in my case, I have no choice. I have to slow down the MG with whatever. I have felt much better since the imuran, predisone, and lots of mestinon.
No one can say if I will continue to be better or not,but seems to be working.
I hate to say this, but try to find some medical financial support somewhere. MG can be a bit expensive to treat. Doctors, test, medications, and all. But, you must do it, or you will become very ill. Then you will be of no use to your family.
Hope you find help
