Demulen® (ethynodiol diacetate/ethinyl estradiol) is prescribed for preventing pregnancy. It is a combined hormonal contraceptive that contains two different hormones (estrogen and progestin).
As a type of birth control, Demulen works to prevent pregnancy mainly by stopping ovulation. However, it also works by changing the cervical mucus (making it more difficult for sperm to enter the uterus) and by altering the lining of the uterus (making it less receptive to an embryo).
Although most women tolerate this birth control pill
well, Demulen can cause side effects, such as nausea, breast tenderness, and headaches
. Before taking this pill, make sure your healthcare provider is aware of any other medical conditions you may have and any other medications you are taking (including nonprescription medicines and herbal supplements).
It is important to take Demulen every day, at the same time every day. Taking it late or missing doses can significantly increase your risk of unintentional pregnancy.
