Full Definition
Vivitrol is a brand name for extended-release naltrexone administered as a monthly intramuscular injection. This formulation provides sustained opioid and alcohol receptor blockade for approximately 28 days, eliminating daily medication compliance issues. Vivitrol is indicated for both opioid use disorder (after complete detoxification) and alcohol use disorder as part of comprehensive treatment programs. The injection must be administered by healthcare professionals and requires patients to be opioid-free for 7-14 days before initiation to avoid precipitated withdrawal.
