Naltrexone

Naltrexone

    Naltrexone blocks the effects of opioid medication including pain relief or feelings of well-being that can lead to opioid abuse. Naltrexone is used as part of a treatment program for drug or alcohol dependence.

    Naltrexone is used to prevent relapse in people who became dependent on opioid medicine and then stopped using it. Naltrexone can help keep you from feeling a “need” to use the opioid.

  • Naltrexone is also used to treat alcoholism by reducing your urge to drink alcohol. This may help you drink less or stop drinking completely. Naltrexone will not cause you to “sober up” and will not decrease the effects of alcohol you recently consumed.

    Naltrexone is not a cure for drug addiction or alcoholism.

    Naltrexone is taken by mouth with or without food, usually 50 milligrams once daily or as directed by your doctor.

  • Effects of naloxone

    Naloxone cannot be used to get high, so it has no potential for misuse. There is no evidence that extended use of naloxone can cause harmful physical effects or dependence. People who take naloxone do not develop a tolerance to its effects and there have been no reported deaths from naloxone overdose.
