What is Natazia?

Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive (COC) use; this risk increases in women who are over 35 years of age and with number of cigarettes smoked. COCs should not be used by women who are over 35 years of age and smoke .

Estradiol valerate and dienogest combination is used to prevent pregnancy. It is a birth control pill that contains two types of hormones, estrogens and progestins and, when taken properly, prevents pregnancy. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization is prevented.

Estradiol valerate and dienogest combination is also used to treat heavy menstrual bleeding that is not caused by any diagnosed conditions of the uterus (womb) in women who choose to use birth control pills.

No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective. Discuss with your doctor your options for birth control.

Estradiol valerate and dienogest combination does not prevent AIDS or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.

This medicine is available only with your doctor's prescription.

To make using hormonal contraceptives as safe and reliable as possible, you should understand how and when to use them and what effects may be expected.

This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

This medicine is available in blister packs. Each blister pack contains 28 tablets with different colors that need to be taken in the same order as directed on the blister pack.

When you begin using this medicine, your body will require at least 9 days to adjust before a pregnancy will be prevented. Use a second form of contraception, such as a condom, spermicide, or diaphragm, for the first 9 days of your first cycle of pills.

Take this medicine at the same time each day, such as after the evening meal or at bedtime. Do not skip or delay taking your pill by more than 12 hours. If you miss a dose, you could get pregnant. Ask your doctor for ways to help you remember to take your pills, or about using another method of birth control.

You must also use a second method of birth control (e.g., condom, diaphragm, spermicide) for the first 9 days you take this medicine.

If you are switching from a progestin-only method (e.g., progestin-only pill, implant, injection, intrauterine system) to using Natazia®, take the first dark yellow pill on the day you would have taken your next progestin-only pill, or on the day your implant or IUD is removed, or on the day you would have your next injection.
