Major

carBAMazepine fruquintinib

Applies to: Epitol (carbamazepine) and fruquintinib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with potent inducers of CYP450 3A4 may decrease the plasma concentrations of fruquintinib, which is primarily metabolized by the isoenzyme. Concomitant use with rifampin, a potent CYP450 3A4 inducer, decreased fruquintinib peak plasma concentration (Cmax) and systemic exposure (AUC) by 12% and 65%, respectively. Reduced efficacy of fruquintinib may occur.

MANAGEMENT: Coadministration of fruquintinib with potent CYP450 3A4 inducers should be avoided.

You should preferably avoid the regular consumption of grapefruits and grapefruit juice while taking carBAMazepine. This can cause carBAMazepine levels to increase. You should report signs of carBAMazepine side effects such as nausea, visual disturbances, dizziness, or muscle weakness to your doctor. You should avoid or limit the use of alcohol while being treated with carBAMazepine. Alcohol can increase the nervous system side effects of carBAMazepine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment.
