What is Natazia?
Natazia contains a combination of dienogest and estradiol. Dienogest and estradiol are female hormones that prevent ovulation (the release of an egg from an ovary). This medicine 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.
Natazia is used to prevent pregnancy.
Natazia is also used to treat heavy menstrual bleeding that is not caused by any medical condition of the uterus.
Do not use Natazia if you are pregnant or if you have recently had a baby.
You should not take Natazia if you have any of the following conditions: uncontrolled high blood pressure, heart disease, a blood-clotting disorder, circulation problems, diabetic problems with your eyes or kidneys, unusual vaginal bleeding, liver disease or liver cancer, severe migraine headaches, if you smoke and are over 35, or if you have ever had breast or uterine cancer, a heart attack, a stroke, or a blood clot.
Taking Natazia can increase your risk of blood clots, stroke, or heart attack, especially if you have certain other conditions, or if you are overweight.
Smoking can greatly increase your risk of blood clots, stroke, or heart attack. You should not take Natazia if you smoke and are over 35 years old.
Missing a pill increases your risk of becoming pregnant. Carefully follow the "missed dose" instructions if you forget to take your medicine.
Some drugs can make Natazia less effective in preventing pregnancy, including antibiotics, hepatitis C medications, HIV/AIDS medications, seizure medications, or barbiturate sedatives. Tell your doctor about all other medications you use.
