What is ethinyl estradiol and levonorgestrel (EC)?

0

Ethinyl estradiol and levonorgestrel are forms of estrogen and progesterone, which are both female hormones involved in conception. Ethinyl estradiol and levonorgestrel are used together in this product as an emergency contraceptive (EC) to prevent pregnancy after contraceptive failure or unprotected intercourse. Ethinyl estradiol and levonorgestrel prevent ovulation (the release of an egg from an ovary), disrupt fertilization (joining of the egg and sperm), and inhibit implantation (attachment of a fertilized egg to the uterus). Ethinyl estradiol and levonorgestrel (EC) may also be used for purposes other than those listed in this medication guide.
