What is dienogest and estradiol (Natazia)?
Dienogest and estradiol 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.
Dienogest and estradiol is used as contraception to prevent pregnancy. Dienogest and estradiol is also used to treat heavy menstrual bleeding that is not caused by any medical condition of the uterus.
Dienogest and estradiol may also be used for purposes not listed in this medication guide.

If you are switching from another birth control pill, start taking dienogest and estradiol on the first day of your withdrawal bleeding. If you were taking progestin-only pills, start taking dienogest and estradiol on the day you would have taken your next pill.
If you are switching from a birth control implant, intrauterine device (IUD), vaginal ring, or skin patch, start taking dienogest and estradiol on the day the other birth control device is removed.
If you are switching from a birth control injection, start taking dienogest and estradiol on the day you would have received your next scheduled injection.
You may have breakthrough bleeding. Tell your doctor if this bleeding continues or is very heavy. You may also have very little or no bleeding during your periods.
