Aleve (Naproxen Sodium) OTC Dosing Guide
Aleve is the brand name for naproxen sodium, a nonsteroidal anti-inflammatory drug (NSAID) sold over the counter in 220 mg tablets, caplets, and gelcaps (equivalent to 200 mg naproxen base plus 20 mg sodium). This calculator applies the standard directions printed on the Aleve Drug Facts label to your age and a couple of health details, showing the initial dose, the ongoing maintenance schedule, the 24-hour maximum, and how many days you can self-treat before checking with a doctor.
How the standard OTC dosing schedule works
For adults and children 12 years and older with no special precautions, the label allows 1 tablet (220 mg) every 8 to 12 hours, with an option to take 2 tablets (440 mg) for the very first dose if needed. No more than 2 tablets should be taken in any 8-12 hour period, and the total must not exceed 3 tablets (660 mg) in 24 hours. The label also caps self-treatment duration: no more than 10 days for pain or 3 days for fever without a doctor's direction, since both are signals that a more serious condition may need evaluation.
Who needs a lower dose or should ask a doctor first
The label specifically calls out adults 65 and older, and anyone with kidney disease, liver disease, heart disease, or who takes a blood thinner, as needing a more cautious approach: no more than 1 tablet every 12 hours, and no more than 2 tablets (440 mg) in 24 hours, only after checking with a doctor. Naproxen is not recommended over the counter for children under 12 - pediatric dosing (commonly 5-7 mg/kg per dose in prescription settings) is weight-based and must be determined and supervised by a physician, not estimated with a generic calculator.
Important safety information
Like all NSAIDs, naproxen carries a labeled risk of stomach bleeding and cardiovascular events that increases with higher doses, longer use, and age. Avoid combining Aleve with other NSAIDs (ibuprofen, aspirin) unless a doctor says otherwise, use the smallest effective dose for the shortest time needed, and stop and seek medical care for symptoms such as black or bloody stools, chest pain, shortness of breath, or slurred speech. This tool is educational only, reflects general OTC label directions rather than a prescription, and is not a substitute for advice from a pharmacist or physician who knows your full medical history.
