Consumer information for this interaction is not currently available.
MONITOR: Coadministration of methotrexate with other agents known to induce hepatotoxicity may potentiate the risk of liver injury. Methotrexate, especially at higher doses or with prolonged treatment, has been associated with hepatotoxicity including acute hepatitis, chronic fibrosis, necrosis, cirrhosis, and liver enzyme elevations.
MANAGEMENT: The risk of hepatic injury should be considered when methotrexate is used with other potentially hepatotoxic agents (e.g., acetaminophen; alcohol; androgens and anabolic steroids; antituberculous agents; azole antifungal agents; ACE inhibitors; cyclosporine (high dosages); disulfiram; endothelin receptor antagonists; interferons; ketolide and macrolide antibiotics; kinase inhibitors; minocycline; nonsteroidal anti-inflammatory agents; nucleoside reverse transcriptase inhibitors; proteasome inhibitors; retinoids; sulfonamides; tamoxifen; thiazolidinediones; tolvaptan; vincristine; zileuton; anticonvulsants such as carbamazepine, hydantoins, felbamate, and valproic acid; lipid-lowering medications such as fenofibrate, lomitapide, mipomersen, niacin, and statins; herbals and nutritional supplements such as black cohosh, chaparral, comfrey, DHEA, kava, pennyroyal oil, and red yeast rice). Baseline and periodic monitoring of hepatic function is recommended, while liver biopsy may be warranted during long-term use of methotrexate. Patients should be advised to seek medical attention if they experience potential signs and symptoms of hepatotoxicity such as fever, rash, itching, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, pale stools, and jaundice.
