What is ethinyl estradiol and norgestrel (Lo Ovral)?

Ethinyl estradiol and norgestrel 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 norgestrel is used as contraception to prevent pregnancy.

Ethinyl estradiol and norgestrel may also be used for other purposes not listed in this medication guide.
