Revia Naltrexon. Dosage, Side Effects, Interactions
Naltrexone blocks the effects of opioid medications, including relieving pain or feeling well, which can lead to opioid abuse. An opioid is sometimes called a narcotic. Naltrexone is used as part of a treatment program for drug or alcohol addiction.
Naltrexone is used to prevent relapse in people who have become addicted to opioid drugs and then stopped using them. Naltrexone can help you not feel the need to use the opioid.
Naltrexone is also used to treat alcoholism by reducing your urge to drink alcohol. This can help you drink less or stop drinking altogether. Naltrexone will not make you ‘sober’ and will not reduce the effects of any alcohol you have recently consumed.
Naltrexone is not a cure for drug addiction or alcoholism.
Naltrexone may also be used for purposes not listed in this medication guide.
