Interactions between your drugs

Major

ethinyl estradiol mavacamten

Applies to: Demulen 1 / 35 (ethinyl estradiol / ethynodiol) and mavacamten

Mavacamten may reduce the blood levels and effects of ethinyl estradiol, which may make it less reliable as a form of birth control. Alternative or additional methods of birth control should be used during treatment with mavacamten and for 4 months after the last dose to avoid unintended pregnancy. This is particularly important because mavacamten 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.
