Ethinyl estradiol and levonorgestrel contains a combination of female hormones that prevent
ovulation (the release of an egg from an ovary). This medication also causes changes in your cervical
mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to
attach to the uterus.
Ethinyl estradiol and levonorgestrel are used as contraception to prevent pregnancy.
Ethinyl estradiol and levonorgestrel may also be used for other purposes not listed in this
medication guide.
