Interactions between your drugs

Major

ethinyl estradiol encorafenib

Applies to: Mono-Linyah (ethinyl estradiol / norgestimate) and encorafenib

Encorafenib may reduce the blood levels and effects of ethinyl estradiol, which may make it less reliable as a form of birth control. Alternative, non-hormonal methods of birth control should be used during treatment with encorafenib to avoid unintended pregnancy. This is particularly important because encorafenib may cause harm in the unborn child. Talk to your gynecologist or other healthcare professional for help in selecting an effective method of birth control that is best for you. If you take hormone replacement for menopause, you should contact your doctor if you experience increased frequency or worsening of your symptoms such as hot flashes, vaginal dryness, or abnormal bleeding. 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.

MONITOR: Coadministration of ethinyl estradiol may increase the plasma concentrations of drugs that are primarily metabolized by CYP450 1A2. In a study of 30 healthy volunteers administered the CYP450 1A2 substrate tizanidine, the systemic exposure (AUC) of tizanidine was 3.9 times greater in women using an oral contraceptive containing ethinyl estradiol.

MANAGEMENT: Patients should be monitored for increased adverse effects of the CYP450 1A2 substrate during concomitant use with ethinyl estradiol. Product labeling for the specific CYP450 1A2 substrate should be consulted for additional recommendations.
