Consequently, estazolam should be avoided in patients receiving ketoconazole and itraconazole, which are very potent inhibitors of CYP3A (see CONTRAINDICATIONS ).
From the Fluconazole label · effective 2026-04-02
Short-acting benzodiazepines Following oral administration of midazolam, fluconazole resulted in substantial increases in midazolam concentrations and psychomotor effects.
If short-acting benzodiazepines, which are metabolized by the cytochrome P450 system, are concomitantly administered with fluconazole, consideration should be given to decreasing the benzodiazepine dosage, and the patients should be appropriately monitored.
