Little-known prescription pill is helping Americans drink less alcohol

Recent studies continue to support a decades-old drug as an alternative means of reducing alcohol consumption.

The prescription opioid pill, called naltrexone, was first approved by the FDA to treat opioid dependence in 1984. A decade later, it was approved for alcohol use disorder.

In addition to the daily pill version, naltrexone is also available as a monthly injectable therapy, which was approved for alcohol use disorder in 2006 and opioid use disorder in 2010.
