In the United States, the Food and Drug Administration (FDA) approved it as an over-the-counter (OTC) drug in 1994. OTC preparations of naproxen in the U.S. are mainly marketed by Bayer HealthCare under the brand 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. In the Netherlands, 220 mg and 275 mg tablets are available OTC in drugstores, 550 mg is OTC only at pharmacies. Aleve became available over the counter in some provinces in Canada on 14 July 2009, but not British Columbia, Quebec or Newfoundland and Labrador; it subsequently became available OTC in British Columbia in January 2010. Research
Naproxen may have antiviral activity against influenza. In laboratory research, it blocks the RNA-binding groove of the nucleoprotein of the virus, preventing formation of the ribonucleoprotein complex—thus taking the viral nucleoproteins out of circulation. Veterinary use
Horses
Naproxen is given by mouth to horses at a dose of 10 mg/kg, and has shown to have a wide safety margin (no toxicity when given at three times the recommended dose for 42 days).
Gender identity disorder first appeared as a diagnosis in the DSM-III (1980), where it appeared under "psychosexual disorders" but was used only for the childhood diagnosis. Adolescents and adults received a diagnosis of transsexualism (homosexual, heterosexual, or asexual type). The DSM-III-R (1987) added "Gender Identity Disorder of Adolescence and Adulthood, Non-Transsexual Type" (GIDAANT). DSM-V (2013) replaced gender identity disorder (GID) with gender dysphoria (GD) to avoid the stigma of the term disorder. Society and culture
Researchers disagree about the nature of distress and impairment in people with GD. Some authors have suggested that people with GD suffer because they are stigmatized and victimized; and that, if society had less strict gender divisions, transgender people would suffer less.Some controversy surrounds the creation of the GD diagnosis, with Davy et al. stating that although the creators of the diagnosis state that it has rigorous scientific support, "it is impossible to scrutinize such claims, since the discussions, methodological processes, and promised field trials of the diagnosis have not been published. "Some cultures have three or more defined genders. The existence of accepted social categories other than man or woman may alleviate the distress associated with cross-gender identity. For example, in Samoa, the faafafine, a group of feminine males, are mostly socially accepted. The faafafine appear similar to transgender women in terms of their lifelong identities and gendered behavior, but experience far less distress than do transgender women in Western cultures.
