GENERALLY AVOID: Coadministration of naltrexone with other agents known to induce hepatotoxicity may potentiate the risk of liver injury. Naltrexone, especially in larger than recommended doses (more than 50 mg/day), has been associated with hepatocellular injury, hepatitis, and elevations in liver transaminases and bilirubin.

MANAGEMENT: The use of naltrexone in combination with other potentially hepatotoxic agents (e.g., alcohol; androgens and anabolic steroids; antituberculous agents; azole antifungal agents; ACE inhibitors; endothelin receptor antagonists; interferons; nucleoside reverse transcriptase inhibitors; thiazolidinediones; anticonvulsants such as carbamazepine, hydantoins, felbamate, and valproic acid; lipid-lowering medications such as fenofibrate, HMG-CoA reductase inhibitors, and niacin; herbal products such as kava and echinacea) is generally not recommended unless the potential benefit outweighs the risk. Periodic monitoring of hepatic function is advisable.
