GENERALLY AVOID: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations and pharmacologic effects of perampanel, which is primarily metabolized by the isoenzyme. The interaction has been reported with known CYP450 3A4 inducers such as carbamazepine, oxcarbazepine, and phenytoin.

MANAGEMENT: According to the manufacturer, concomitant use of perampanel with strong CYP450 3A4 inducers should be avoided.

Alcohol can increase the nervous system side effects of perampanel such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with perampanel. Do not use more than the recommended dose of perampanel, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
