Provigil Interactions


May antagonize hormonal contraceptives; use alternative or additional contraceptive method during and for one month after treatment. Avoid alcohol. Caution with MAOIs. Modafinil levels may be decreased by CYP3A4 inducers (eg, carbamazepine, phenobarbital, rifampin) and increased by CYP3A4 inhibitors (eg, ketoconazole, erythromycin). May decrease levels of drugs metabolized by CYP3A4 (eg, cyclosporine, midazolam), CYP1A2 or CYP2B6. May increase levels of drugs metabolized by CYP2C9 (eg, warfarin) or CYP2C19 (eg, phenytoin, diazepam, propranolol), and levels of tricyclics and SSRIs in patients deficient in CYP2D6 (consider dose reduction). Monitor warfarin, phenytoin.
