Interactions between your drugs

Moderate

palovarotene vorasidenib

Applies to: palovarotene and vorasidenib

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations and pharmacologic effects of palovarotene, which is primarily metabolized by the isoenzyme. Concomitant use with rifampin, a potent CYP450 3A4 inducer, decreased the peak plasma concentration and systemic exposure of palovarotene by 81% and 89%, respectively. Data are not available for palovarotene in combination with other, less potent CYP450 3A4 inducers.

MANAGEMENT: The potential for diminished pharmacologic effects of palovarotene should be considered during coadministration with CYP450 3A4 inducers. Alternative treatments may be required if an interaction is suspected.

Drug and food interactions

Major

palovarotene food

Applies to: palovarotene

Grapefruit, pomelo, and juices or supplements containing these fruits may increase the blood levels of palovarotene, which may increase the risk and/or severity of side effects such as dry skin, dry lips, hair loss, skin rash, itching, skin and nail infection, dry eyes, night blindness, depression, and mood changes. It may also increase the risk of a rare, but potentially serious, condition called pseudotumor cerebri caused by increased pressure in the brain. Palovarotene should be taken with food at approximately the same time each day. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. 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.
