What is Seasonale?
Seasonale contains two female hormones that prevent ovulation (the release of an egg from an ovary). It 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. Seasonale is used as contraception to prevent pregnancy. Seasonale may also be used for purposes other than those listed in this medication guide.
