Naproxen, sold under the brand name Aleve among others, is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, menstrual cramps, and inflammatory diseases such as rheumatoid arthritis, gout and fever.[8] It is taken orally.[8] It is available in immediate and delayed release formulations.[8] Onset of effects is within an hour and lasts for up to twelve hours.[8] Naproxen is also available in salt form, naproxen sodium, which has better solubility when taken orally.[9]

Common side effects include dizziness, headache, bruising, allergic reactions, heartburn, and stomach pain.[8] Severe side effects include an increased risk of heart disease, stroke, gastrointestinal bleeding, and stomach ulcers.[8] The heart disease risk may be lower than with other NSAIDs.[8] It is not recommended in people with kidney problems.[8] Use is not recommended in the third trimester of pregnancy.[8]

Naproxen is a nonselective COX inhibitor.[8] As an NSAID, naproxen appears to exert its anti-inflammatory action by reducing the production of inflammatory mediators called prostaglandins.[10] It is metabolized by the liver to inactive metabolites.[8]

Naproxen was patented in 1967, and approved for medical use in the United States in 1976.[11][8][12] In the United States it is available over the counter and as a generic medication.[8][13] In 2022, it was the 88th most commonly prescribed medication in the United States, with more than 7 million prescriptions.[14][15]
