Hi, and welcome. 60 mg. is the standard starting dose for Mestinon. But Mestinon has a very short half-life. If he finds that he feels better after he takes it, but gets weak again before the next dose, he should ask his doctor about taking the pills closer together. That's typically how it's done: you still take 60 mg. pills, but instead of three times a day, you might take them four or five times a day.
