Naltrexone is a medication that can be used to treat both opioid and alcohol use disorders.
ReVia®, Depade®, and Vivitrol®
Oral tablet or monthly injection
How It Works
For opioid use disorders, naltrexone functions by attaching to opioid receptors in the brain without activating them—blocking them, essentially. As a result, opioids cannot attach to the brain receptors and have no effect. A patient must be opioid-free for at seven days before beginning treatment with naltrexone.
For alcohol use disorders, naltrexone decreases urges to drink alcohol.
Clinical studies show that naltrexone sold as Vivitrol is non-addictive, safe, and effective at reducing opioid dependence and cravings for patients who stick with the treatment.
