Aleve (Naproxen) Dosage Calculator

Health

The Aleve (Naproxen Sodium) Dosage Calculator adds up your total daily naproxen sodium intake from the tablet strength and number of doses, and flags whether it stays within the 660 mg over-the-counter daily limit for adults.

Rates and fees change frequently. Always confirm the current figures with the official authority before relying on this result.

Formula

Daily total = Tablet strength × Doses per day (OTC adult max 660 mg/day)
  • Standard OTC Aleve tablets contain 220 mg of naproxen sodium.
  • Daily total = tablet strength × number of doses taken in 24 hours.
  • The OTC limit for adults is 660 mg/day (three 220 mg tablets); the typical schedule is one tablet every 8–12 hours.
  • Higher prescription doses exist but must be directed by a doctor. This tool is for adults; it is not for children under 12 without medical advice.

Example Calculation

Inputs
  • Tablet Strength (mg): 220
  • Doses Per Day: 2

Two 220 mg Aleve tablets in a day give 220 × 2 = 440 mg, which is within the 660 mg OTC daily limit for adults.
