Hi,

Mestinon is actually used to increase standing blood pressure by the mayo clinic. My dr here in the UK has asked me to try it (I suffer from dysautonomia - problems with my autonomic nervous system of which syncope, low blood pressure,orthostatic hypotension, poor temperature regulation and postural orthostatic tachycardia are just some of the fun things I live with!).

With regard to your syncope it is possible that the MG has caused problems with your autonomic nervous system. Many people with auto immune disorders go on to develop such problems.

I would suggest that you take a look at this forum

where many of the people suffer from Postural Orthostatic Tacycardia syndrome, Syncope (many different types) and other issues to do with the autonomic nervous system along with various autoimmune diseases.

It sounds like you could be suffering with orthostatic hypotension have a look at the above link which mentions mestinon.
