How Long Can You Take Vivitrol?

Medically Reviewed by Johnelle Smith, M.D. on May 27, 2022

A person prescribed Vivitrol can continue to be on the injectable naltrexone as long as they and their healthcare provider determine it is an acceptable time frame.

How Long Can You Take Vivitrol

As long as there are no severe health risks to the patient, and the person is not actively using opioids, they can use Vivitrol for as long as is necessary.

Vivitrol (naltrexone) is a prescription medication treatment option for alcohol use disorder (AUD) and opioid use disorder (OUD).

Naltrexone is not an opioid, therefore it does not carry the same concern for addiction or abuse that some other medication-assisted treatment (MAT) medications carry.
