Prior to taking mestinon, I had diarrhea all the time. Immodium was my best friend. I never took more than the maximum daily dose. I never left the house without it and took it several times a day, several days a week without any consequences.

Surprisingly, once I started mestinon, I never had another bout of diarrhea. I do not understand why. I always thought my diarrhea was another autoimmune component. I do not understand how it got fixed but I am glad. I am up to 90mg x4 of mestinon and have had no side affects.

So sorry you are having these side affects. MG is exhausting enough. The diarrhea just wipes you out even more.

take care of your self
