Modafinil Tablets 200 mg (Modafinil)

Adult dose

Adults: Administer (take) 200mg orally once daily in the morning. (Although 400mg once daily was well tolerated, there is no clear evidence that it is more effective than 200mg.) The dose should be adjusted when coadministered with CYP3A4 substrate drugs such as triazolam and cyclosporine. Drugs primarily eliminated through CYP2C19 metabolism, such as diazepam, propranolol, phenytoin (or via CYP2C9), and S-mephenytoin, have prolonged elimination when coadministered with this drug; therefore, reduce their doses and monitor for toxicity. For patients with severe hepatic impairment, reduce the dose to 1/2 of the usual adult dose (100mg/day).

This medication may not restore alertness in patients with severe drowsiness, so it is advisable to check drowsiness levels frequently and avoid driving or hazardous tasks.
