I am just wondering if someone out there has been switched from Mestinon to some other drug to help control their Myasthenia Gravis. I have tried to take it but have had to stop because not only do I have an undiagnosed neuromuscular disease I also have chronic ITP with chronic anemia and the Mestinon gave me ulcers. I am now going through 4 days a month of IVIG infusions, this works for a couple of weeks after I have it but does not seem to last until I get the next dose of it each month. Any information would be grately appreciated. Thank YOU
