What is ethinyl estradiol and levonorgestrel extended-cycle?
Ethinyl estradiol and levonorgestrel extended-cycle 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 extended-cycle are used as contraception to prevent pregnancy. Ethinyl estradiol and levonorgestrel extended-cycle may also be used for other purposes not listed in this medication guide.
