Naltrexone can be used in two forms to treat alcohol addiction:
1. Oral Naltrexone: Taken in pill form (usually 50 mg), this version can be prescribed for daily use or as part of the "targeted" approach, also known as The Sinclair Method (TSM). In TSM, the medication is taken one hour before drinking, helping to reduce the desire for further alcohol consumption during a session. Over time, it retrains the brain to associate less reward with drinking.
2. Extended-release Injectable Naltrexone (Vivitrol): This version of naltrexone is administered as a monthly injection by a healthcare provider. It delivers a continuous dose of the medication, which can be particularly helpful for individuals who struggle with adherence to daily medication or who prefer less frequent dosing.
Both forms are most effective when combined with counseling or therapy, helping to address the underlying psychological components of alcohol addiction.
