Interactions between your drugs

Moderate

bosutinib oritavancin

Applies to: bosutinib and oritavancin

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of bosutinib, which is primarily metabolized by the isoenzyme. In 24 healthy volunteers, administration of a single 500 mg dose of bosutinib with the potent CYP450 3A4 inducer rifampin (600 mg/day for 6 days) under fed conditions resulted in an 86% decrease in bosutinib peak plasma concentration (Cmax) and 94% decrease in systemic exposure (AUC) compared to administration of bosutinib alone. No data are available for use with less potent CYP450 3A4 inducers.

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

Drug and food interactions

Moderate

bosutinib food

Applies to: bosutinib

Bosutinib should be taken with a meal to help with its absorption. Do not consume grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with bosutinib unless directed otherwise by your doctor. Grapefruit juice can significantly increase the blood levels of bosutinib. You may be more likely to experience side effects such as nausea, vomiting, abdominal pain, diarrhea, liver damage, and impaired bone marrow function resulting in low numbers of different types of blood cells, which can increase the risk of anemia, bleeding problems, and infections. 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.
