That's pretty much it, Kelly. Most myasthenic crises happen within the first couple years, so step one is always an attempt to stabilize the symptoms. And, if you are lucky, that can usually be done with pyridostigmine and some prednisone. That doesn't mean all your symptoms will go away. That probably will never happen. But your symptoms will be milder and more predictable. For me, pyridostigmine was a wonder drug. It opened and corrected my vision, put strength back into my neck and allowed me to chew and swallow normally. But pyridostigmine does nothing to address your underling issue, which is the production of a destructive antibody.
So, step two is to find a med that will reduce the production of the antibody. That is critical because your antibody - AChR Binding antibody in my case - is not just destroying your messenger cells but is destroying the little receptors on your muscles. Losing those receptors is permanent and progressive. There are a lot of new meds in development which might target just the antibody, but right now the standard treatment is an immunosuppressant which impedes production of all antibodies, not just the bad one. It's an imperfect solution, but it's what we have.
IVIG treatments are somewhat unusual but understandable if your doctor is (A) unsatisfied with the symptom control you are getting or (B) is moving you to an immunosuppressant and wants some interim control of your symptoms during the many months it can take for immunosuppressant to begin working.
Once the immunosuppressant is working, you can usually stop or dramatically reduce your intake of pyridostigmine and prednisone. Good luck Kelly. Keep reading and researching..
