Natazia

Generic Name: estradiol valerate/dienogest (ES-tra-DYE-ol VAL-er-ate/dye-EN-oh-jest)
Brand Name: Natazia

Cigarette smoking increases the risk of serious heart problems associated with use of Natazia. This risk increases with age (especially in women older than 35 years old) and with frequent smoking. Women who are older than 35 years old and smoke should not use Natazia.


Natazia is used for:

Preventing pregnancy. It may also be used to treat heavy menstrual bleeding in women who use Natazia for birth control. It may be used for other conditions as determined by your doctor.

Natazia is a combination birth control pill. It works by preventing ovulation. It may also change cervical mucus to prevent the sperm from reaching the egg and change the lining of the uterus to prevent a fertilized egg from implanting in the uterus. It works to decrease heavy menstrual bleeding by thinning the lining of the uterus.

Do NOT use Natazia if:

  • you are allergic to any ingredient in Natazia
  • you are pregnant or think you may be pregnant
  • you have a history of blood clotting problems, severe blood clots (eg, in the lungs, legs, eyes), certain blood vessel problems (eg, bleeding in the brain, heart attack, stroke), or certain cancers (eg, breast cancer, endometrial cancer, cervical cancer)
  • you are at risk of developing severe blood clots or have certain heart problems (eg, certain heart valve problems, certain types of irregular heartbeat)
  • you have certain types of headaches or migraines with or without aura; severe or uncontrolled high blood pressure; undiagnosed abnormal vaginal bleeding; or diabetes that affects your eyes, kidneys, or circulation
  • you have liver disease, liver tumors or cancer, or a history of yellowing of the eyes or skin caused by pregnancy or prior birth control use
  • you have had surgery and are or will be confined to a bed or a chair for an extended period of time
  • you are older than 35 years old and you smoke cigarettes
  • you are taking carbamazepine, phenytoin, rifampin, or St. John's wort

Contact your doctor or health care provider right away if any of these apply to you.
