Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration with moderate inhibitors of CYP450 3A4 may significantly increase the plasma concentrations of encorafenib, which is primarily metabolized by the isoenzyme. When a single 50 mg dose of encorafenib (equivalent to 0.1 times the recommended dose) was administered with diltiazem, a moderate CYP450 3A4 inhibitor, encorafenib peak plasma concentration (Cmax) increased by 45% and systemic exposure (AUC) increased by 2-fold. Increased exposure to encorafenib may increase the risk of serious and life-threatening adverse effects such as hemorrhage, uveitis, QT prolongation, hepatotoxicity, dermatologic reactions, and new malignancies.
MANAGEMENT: Concomitant use of encorafenib with moderate CYP450 3A4 inhibitors should generally be avoided. If coadministration is required, the manufacturer recommends reducing the encorafenib dose to one-half of the dose used prior to addition of the moderate CYP450 3A4 inhibitor. After the inhibitor has been discontinued for 3 to 5 elimination half-lives, the encorafenib dose that was taken prior to initiating the inhibitor may be resumed.

You should preferably avoid consumption of grapefruit and grapefruit juice while taking encorafenib. Grapefruit and grapefruit juice can significantly increase the blood levels of encorafenib. This may increase the risk of serious side effects such as bleeding complications, eye and vision problems, liver problems, irregular heart rhythm, and development of new skin cancers. Talk to your doctor 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.
