I u took ibuprofen at 6 a.m. and its now 1 in the afternoon can u take an aleve (naproxen)?

Of course: The maximum daily dose of aleve (naproxen) is 1100 mg. Always ask your doctor for more information about medication and your individual situation.

Mixing meds: ibuprofen( advil) has a half life of about 2 hours and naproxen Aleve) 12 to 17 hours . So after about 7 hours the effect of the ibuprofen is much reduced and you could take naproxen . Not so the other way around
