التداخل بين درونابينول وإيفافيرينز

Monitor for increased dronabinol-related adverse reactions when dronabinol oral solution is co-administered with inhibitors of CYP2C9 (e.g., amiodarone, fluconazole) and inhibitors of CYP3A4 enzymes (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, erythromycin, grapefruit juice).

Cannabinoid Test Interaction Efavirenz does not bind to cannabinoid receptors.

False-positive urine cannabinoid test results have been reported with some screening assays in uninfected and HIV-infected subjects receiving efavirenz.

Confirmation of positive screening tests for cannabinoids by a more specific method is recommended.
