Vivitrol, the brand name for the naltrexone shot, is an FDA-approved medication for treating opioid use disorder (OUD) and alcohol use disorder (AUD). This injectable version of naltrexone makes treatment more convenient as it is delivered as a once-monthly shot instead of daily tablets. Whether you are interested in oral or injectable naltrexone treatment, you should always access your medication from a qualified provider and a licensed pharmacy.
If you need help managing opioid or alcohol cravings, you may be a good candidate for oral naltrexone treatment through Confidant Health. Our online medication-assisted treatment allows you to receive support for OUD and AUD from the comfort of home. We offer oral naltrexone and Suboxone care through our online Suboxone clinic but can help you find a local provider if monthly injectable treatment is more suitable for you.

What Is a Naltrexone Shot (Vivitrol)?
Naltrexone is prescribed to reduce cravings in people trying to overcome opioid or alcohol use disorder. The medication is offered in two forms: tablets and injections. A naltrexone shot or injection (XR-NTX) is delivered as a monthly extended-release intramuscular shot. If you are prescribed injectable naltrexone, you will need to visit your provider once a month to receive your medication.
How Does a Naltrexone Shot (Vivitrol) Work?
Naltrexone is an opioid antagonist that binds to opioid receptors and blocks other opioids from interacting with these receptors and making you feel high. A naltrexone shot works by slowly releasing the medication over 28 days. The effects peak two hours after administration and again two days later. Although the peak is soon after administration, the opioid-blocking effects of the naltrexone shot will continue to work for one month.
Naltrexone Shot (Vivitrol) Prescription
The naltrexone shot (Vivitrol) is offered in one strength: a 380 mg injection. You receive the shot once a month in your provider's office. For many people, this provides the most convenient form of support for opioid and alcohol use disorder.
Naltrexone Shot (Vivitrol) Dosage and Administration
The 380 mg injection is the only dosage of naltrexone available. Your provider will administer the Naltrexone shot in their office once per month.
Naltrexone Shot (Vivitrol) Uses
The primary purpose of the naltrexone shot is to minimize cravings for opioids or alcohol. Naltrexone binds to opioid receptors in the brain and prevents other opioids from attaching to these receptors. This blocks other opioids from inducing euphoria, lessening the motivation to use these substances.
