Vivitrol for Opiate Dependence

Vivitrol® (naltrexone injection) is a prescription medication licensed to help adults stop abusing alcohol or opioid medications. It comes as an injection that is given in the gluteal muscle once every four weeks.
When used for opiate dependence, Vivitrol works by competing with opioids for opioid receptors. Vivitrol produces no effects when it binds to opioid receptors. However, it prevents other opioid medicines from also binding to the receptors, thus blocking the actions of these other opioid medicines.
People who receive treatment with Vivitrol must stop using opioid drugs, such as prescription pain medications and opioid street drugs, for at least 7 to 10 days before receiving Vivitrol injections.
