Interactions between your drugs

Moderate

dexAMETHasone darifenacin

Applies to: Dexamethasone Intensol (dexamethasone) and darifenacin

MONITOR: Theoretically, coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of darifenacin, which has been shown to be a substrate of the isoenzyme.

MANAGEMENT: Pharmacologic response to darifenacin should be monitored more closely whenever a CYP450 3A4 inducer is added to or withdrawn from therapy, and the darifenacin dosage adjusted if necessary.

Drug and food interactions

Minor

darifenacin food

Applies to: darifenacin

The consumption of grapefruit juice may be associated with increased plasma concentrations of darifenacin. The mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. The clinical significance is unknown.
