500 mg naproxin 2xs a day
I have had myasthenia gravis for over 20 years, well controlled with Mestinon 60mg,3xday, and prednisone, 10mg daily, I take naproxen 200mg occasionally, and have had no problems. I've never taken 500mg and would not without doctor's advice. My doctor prefers that I take acetaminophen, but sometimes I need naproxen for severe back pain, unrelated to MG. Hope this helps, I would definitely check with my doctor before taking that much in a day. Good luck!
