Edit list (add/remove drugs)

Interactions between your drugs

Moderate

griseofulvin pimavanserin

Applies to: Grisactin 500 (griseofulvin) and Nuplazid (pimavanserin)

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of pimavanserin, which is primarily metabolized by the isoenzyme. A drug interaction study has shown decreases in pimavanserin Cmax (71%) and AUC (91%) with coadministration of rifampin, a strong CYP450 3A4 inducer.

MANAGEMENT: The possibility of diminished therapeutic response to pimavanserin should be considered during coadministration with CYP450 3A4 inducers. The manufacturer recommends coadministration with strong or moderate CYP450 3A4 inducers be avoided.

MANAGEMENT: Patients should be advised of the possibility of increased adverse effects or a disulfiram-like reaction.
