Interactions between your drugs

Moderate

fedratinib benzgalantamine

Applies to: fedratinib and benzgalantamine

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with fedratinib may increase the plasma concentrations of drugs that are substrates of the CYP450 3A4, 2C19, and/or 2D6 isoenzymes. Coadministration of fedratinib with a single dose each of the CYP450 3A4 substrate midazolam (2 mg), CYP450 2C19 substrate omeprazole (20 mg), and CYP450 2D6 substrate metoprolol (100 mg) increased the systemic exposure (AUC) of the substrates by 4-, 3-, and 2-fold, respectively.

MANAGEMENT: Caution is recommended when fedratinib is used concomitantly with substrates of CYP450 3A4, 2C19, and/or 2D6. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever fedratinib is added to or withdrawn from therapy, particularly those with a narrow therapeutic index.

Drug and food interactions

Moderate

fedratinib food

Applies to: fedratinib

Grapefruit juice can increase the blood levels of fedratinib. This may increase the risk of serious side effects such as Wernicke's encephalopathy, a potentially fatal condition of the brain associated with thiamine (vitamin B1) deficiency; low blood cell counts, which can lead to anemia, bleeding, and infections; severe diarrhea, nausea, and vomiting; problems in the liver or pancreas; and development of other cancers. You should avoid the consumption of grapefruit and grapefruit juice during treatment with fedratinib. You may take the medication with or without food, but taking it with a high-fat meal may help reduce nausea and vomiting. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. 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.
