What is Loestrin Fe?
Fe tablets contains ethinyl estradiol and norethindrone, a combination of female hormones that prevent ovulation (the release of an egg from an ovary). Loestrin Fe 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.Loestrin Fe is used as contraception to prevent pregnancy.
Loestrin Fe may also be used for other purposes not listed in this medication guide.
