What Does Vivitrol Do?
Vivitrol is a long-acting medication that blocks the effects of the illicit opioid heroin and prescription opiates such as oxycodone, morphine, fentanyl, and hydrocodone.
Vivitrol can also reduce cravings for alcohol and help people who are abstinent from alcohol maintain their sobriety, essentially by blocking the pleasurable effects of alcohol.
How A Vivitrol Injection Works
Vivitrol is the brand name for an extended-release injection containing naltrexone, an opioid antagonist that blocks the euphoric and sedative effects of opioids.
This is not a take-home medication. Receiving this medication requires monthly appointments with a healthcare professional.
Who can administer Vivitrol:
- physician assistants
- nurse practitioners
Vivitrol is injected intramuscularly into the buttocks every four weeks, or once a month, after an individual has fully detoxed from other opioids.
After this injection, Vivitrol will begin to take effect about two hours after administration, then peak again two to three days later.
