Naltrexone for Alcohol Craving

When used as part of a comprehensive treatment program, naltrexone (Revia®) can help prevent alcohol craving in people who are trying to stop drinking. This medication comes as a tablet that is taken once daily.
 
It is not exactly known how naltrexone works to treat alcoholism. This drug is known to block opioid receptors, which may help prevent some of the rewarding effects of alcohol use. Naltrexone prevents other substances, such as opioid pain medications, from binding to and activating the receptors, making it helpful in people who are trying to stop using opioid narcotics.
