Naltrexone (Full Dose)

Naltrexone is a medication primarily used in the management of alcohol dependence and opioid dependence. It functions as an opioid antagonist, meaning it blocks the effects of opioid drugs. In the context of alcohol dependence, it is thought to reduce the craving for alcohol and the rewarding effects of drinking, thereby supporting abstinence or reducing heavy drinking. For opioid dependence, it prevents euphoric effects and helps maintain abstinence after detoxification. Naltrexone is available in oral tablet form and as an extended-release injectable formulation (Vivitrol). The full dose typically refers to the oral administration, which generally involves a higher daily amount compared to low-dose naltrexone (LDN). It is important to note that naltrexone is not a narcotic and is not addictive. It does not produce a euphoric effect. Treatment with naltrexone should always be part of a comprehensive management program that includes counseling and psychosocial support, as emphasized by the Substance Abuse and Mental Health Services Administration (SAMHSA).
