Vivitrol (naltrexone) is an addiction treatment medication that carries a risk of liver damage in some people who have liver conditions such as acute hepatitis or liver failure.
Liver damage is not a common side effect of Vivitrol in the general population. Before taking Vivitrol, tell your doctor if you have impaired liver function or have a history of liver disease.
How Does Vivitrol Affect The Liver?
Vivitrol, like most controlled substances, is metabolized by enzymes in the liver. Unlike heavy alcohol use, however, Vivitrol is not a drug that’s associated with a high risk for liver injury.
When taken as directed, Vivitrol is safe and effective as a medication-assisted treatment (MAT) option for people with an alcohol or opioid use disorder.
Signs Of Liver Damage While Taking Vivitrol
Hepatotoxicity, or drug-related liver damage, may be identified by a number of warning signs in people who are taking Vivitrol for drug or alcohol addiction.
Common signs of liver damage include:
- yellowed skin
- yellowing of the whites of the eyes
- stomach pain lasting more than a few days
- loss of appetite
- unusual tiredness
- dark urine
- light-colored bowel movements
- unusual bleeding or bruising
If you or someone you know is showing signs of liver damage after getting a Vivitrol shot, contact your healthcare provider right away. This may require medical attention.

Vivitrol is contradicted, or not advised, for people with acute hepatitis, those with a history of liver failure, or individuals with severely impaired liver function.
