Preven EC contains a combination of ethinyl estradiol and levonorgestrel. Ethinyl estradiol and levonorgestrel are forms of estrogen and progesterone, which are both female hormones involved in conception.

Preven EC is used as an emergency contraceptive (EC) to prevent pregnancy after contraceptive failure or unprotected intercourse. Preven EC prevents 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).
