Took 2 Aleve (naproxen) at 11am, and one at 10pm same day, when is the next safe time I can take, and is taking 2 at same time bad?

About 12 hours... Should take approximately 12 hours apart. Aleve is naproxen 220 mg. It is fine to take 2 Aleve at a time as long as you are hydrated and do not have underlying kidney disease or take large doses of diuretics.
OK to take 2 aleve (naproxen) Ok 3x a day, but you need to know for what reason? If pain persist see doctor.
