Hi,

Yes, this happened to me a few times when I was taking it everyday pretty much around the clock. My neuro did another evaluation and increased the dosage. When my MG started getting better and I had fewer symptoms, I was able to go back down to the lower dosage again. I currently take 60mg every 3-4 hours or as needed or I am able to tolorate it due to the side effects, per my neuro. Have you called your neuro? He may increase it or want to do another evaluation. Please let us know how you make out.

Hugs,
Pat
