Ethinyl estradiol and levonorgestrel is a combination drug that contains 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 is used as contraception to prevent pregnancy. Ethinyl estradiol and levonorgestrel may also be used for purposes not listed in this medication guide.
Sronyx is used to prevent pregnancy. For a woman to get pregnant, an egg is released from the ovary, where it swims to the fallopian tube for fertilization. Sronyx prevents the egg from being released from the ovary. It also affects the uterine lining which makes it hard for a fertilized egg to attach and end up passing out of the body. Do not use this drug if you are already pregnant or if you have recently given birth.
