Generally, up to 1,000 mg/day; that is, 500 mg twice per day. (Note: If taken with Vicodin (contains acetaminophen), then you should take less naproxen, (say 375 mg twice a day, or less if you have liver problems. ) Be sure that you consult your treating doctor or dentist for medical advice, though!
