Vivitrol is a medication that is used to treat alcohol or opioid dependence. The active ingredient in Vivitrol is naltrexone, which is an opioid antagonist. Naltrexone works by binding to the same receptors in the brain that opioids and alcohol bind to, but without producing the same euphoric effects. This means that if a person tries to use opioids or alcohol while taking Vivitrol, they will not feel the same pleasure or high that they normally would.
Vivitrol is administered by injection, and the effects can last for up to four weeks. By reducing cravings for opioids or alcohol, Vivitrol can help individuals in recovery to stay sober and avoid relapse. It is often used as part of a comprehensive treatment program that may also include counseling, support groups, and other medications.
