What is naltrexone?

  • Naltrexone is an opioid antagonist, which means it blocks the effects of opioids such as codeine, morphine, oxycodone, etc.
  • Naltrexone was developed to treat opioid addiction. A standard dose to treat opioid addiction is typically 50 mg once daily. A standard dose of naltrexone is also used to treat alcohol dependence, although we do not fully understand how it works to reduce the urge or desire to drink alcohol.
