Naltrexone (reVia)
Naltrexone is a medication approved by the FDA for use with people addicted to opiates such as heroin, and to alcohol.
When used to treat opiate addiction, Naltrexone acts as a block against the feelings of euphoria created by opiates. It binds to opioid receptors more strongly than other opiates (except buprenorphine), which results in a near complete blocking of opioids. When Naltrexone binds with the receptor site, it does not activate the receptor at all, so withdrawal discomfort or pain may still persist.
Naltrexone has not been found to be addictive or to create a physical dependence. It is often used with clients who have detoxified by need an extra measure of security in the recovery process. Naltrexone is used in treatment facilities, and through doctors’ offices. However, Naltrexone is not used extensively because the patient retention rate is low.
Naltrexone was also approved by the FDA to treat alcoholism, since it tends to reduce alcohol cravings in these patients. Naltrexone should not be confused with other medications that might cause nausea or vomiting if they drink alcohol.
