Consumer:Fosphenytoin may reduce the blood levels and effects of donepezil. Contact your doctor if your symptoms worsen or your condition changes during treatment with these medications. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: Coadministration with drugs that are inducers of the CYP450 3A4 and/or 2D6 enzymatic pathways may decrease the plasma concentrations of donepezil. The mechanism is accelerated clearance of donepezil due to enhanced CYP450 activities.
MANAGEMENT: While clinical data are lacking, the possibility of a diminished therapeutic response to donepezil should be considered in patients receiving concomitant inducer agents.
