Interactions between your drugs

Major

flibanserin encorafenib

Applies to: flibanserin and encorafenib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with potent inducers of CYP450 3A4 may significantly decrease the plasma concentrations of flibanserin, which is primarily metabolized by CYP450 3A4 and, to a lesser extent, by CYP450 2C19. In 24 healthy female subjects, administration of a single 100 mg dose of flibanserin following pretreatment with the potent CYP450 3A4 inducer rifampin (600 mg once daily for 7 days) resulted in a 95% decrease in flibanserin exposure. Loss of therapeutic efficacy may occur.

MANAGEMENT: Concomitant use of flibanserin with potent CYP450 3A4 inducers should generally be avoided.

Drug and food interactions

Major

flibanserin food

Applies to: flibanserin

Do not use alcohol too close to the dosing time of flibanserin. Doing so can cause excessive drowsiness and decreases in blood pressure, which may lead to dizziness, lightheadedness, fainting, and accidental injury. Take flibanserin at bedtime to minimize the risk of these effects. It is recommended that you stop drinking alcohol at least two hours before taking flibanserin; otherwise, you should just skip the flibanserin dose that evening. Alcohol should not be consumed until at least the morning after taking flibanserin at bedtime. Because grapefruit juice can significantly increase the blood levels of flibanserin, you should also avoid the consumption of grapefruit and grapefruit juice during treatment. Talk to your healthcare provider if you have any questions or concerns. 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.
