What is Aleve: Uses, Warnings & Interactions

Updated May 14, 2025  •  Published Dec 30, 2020

Aleve is a brand name line of over-the-counter pain relievers containing naproxen sodium, a pain reliever and fever reducer. Aleve is marketed under a range of product names like Aleve Gelcaps, Aleve Caplets, Aleve Headache Pain, or just plain Aleve. Some Aleve products contain other drugs but these are not the subject of this article. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) similar to aspirin and ibuprofen but it’s less likely to cause some of the side effects of other NSAIDs. People will take doses orally. Naproxen is long-lasting, so a single dose should relieve symptoms for about 12 hours.
