Naproxen sodium (INN) ( /nəˈprɒksən/) is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for the reduction of pain, fever, inflammation and stiffness caused by conditions such as:

It is also used for the treatment of primary dysmenorrhea. It works by inhibiting both the COX-1 and COX-2 enzymes. Naproxen and naproxen sodium are marketed under various trade names, including: Aleve, Anaprox, Antalgin, Feminax Ultra, Flanax, Inza, Midol Extended Relief, Nalgesin, Naposin, Naprelan, Naprogesic, Naprosyn, Narocin, Proxen, Synflex and Xenobid.

Naproxen was originally marketed as the prescription drug Naprosyn by Syntex in 1976, and naproxen sodium was first marketed under the trade name Anaprox in 1980. It remains a prescription-only drug in much of the world. In the United States, the Food and Drug Administration (FDA) approved its use as an over-the-counter (OTC) drug in 1994; OTC preparations in the U.S. are mainly marketed by Bayer HealthCare under the trade name Aleve and generic store brand formulations. In Australia, packets of 275 mg tablets of naproxen sodium are Schedule 2 pharmacy medicines, with a maximum daily dose of 5 tablets or 1375 mg. In the United Kingdom, 250 mg tablets of naproxen were approved for OTC sale under the brand name Feminax Ultra in 2008, for the treatment of primary dysmenorrhoea in women aged 15 to 50. Aleve became available over-the-counter in most provinces in Canada on 14 July 2009, it became available in Quebec during the summer of 2010 but can only be dispensed by a pharmacy employee after an assessment of the patient's needs. It most recently became available in British Columbia in March 2011.
