Description:
Ethinylestradiol is most frequently used as the estrogen component of combined oral contraceptives. Also used for the treatment of menopausal and post menopausal symptoms, especially the vasomotor effects.

Use:
Ethinylestradiol is usually taken by mouth with food or milk either every day or on a cyclical basis: once a day for 21 days and then none for 7 days; then the cycle is repeated. However, for treating cancer it usually is taken three times a day every day for at least 3 months.
