Drug Interactions between ethinyl estradiol / norelgestromin and mobocertinib

Mobocertinib may reduce the blood levels of ethinyl estradiol, which may make it less reliable as a form of birth control. Alternative methods of birth control should be used during treatment with mobocertinib and for 1 month after stopping treatment to avoid unintended pregnancy. This is particularly important because mobocertinib may cause fetal harm. Talk to your gynecologist or other healthcare professional for help in selecting an effective method of birth control that is best for you. Men with female partners of reproductive potential receiving mobocertinib should use a condom during the treatment period and for 1 week after stopping treatment. 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.
