Naltrexone

Naltrexone is a prescription medicine used to help treat alcohol use disorder and opioid dependence. It belongs to a group of medicines that work in the brain to reduce the rewarding effects of alcohol and opioids.

It is used as part of a treatment plan, along with counseling and support. Do not use Naltrexone if you are taking opioids or if you need opioid pain medicine, since it can cause severe withdrawal and block opioid effects.
