It remains a prescription-only drug in much of the world. In the United States, the Food and Drug Administration approved its use as an over-the-counter 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 220 mg tablets. In Australia, packets of 275 mg tablets of naproxen sodium are Schedule 2 pharmacy medicines, with a maximum daily dose of five 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, but not British Columbia, Quebec or Newfoundland and Labrador; it became available OTC in British Columbia in late January 2010.
