What is Natazia (estradiol valerate / dienogest)?

How Natazia (estradiol valerate / dienogest) works

Natazia (estradiol valerate / dienogest) is a combined contraceptive that contains two hormones: estradiol valerate (an estrogen) and dienogest (a progestin). Both hormones work together to prevent pregnancy by:

  • Suppressing ovulation (release of an egg from the ovary)
  • Changing cervical mucus to block sperm movement
  • Creating an unfriendly environment for the fertilized egg by changing the lining in the uterus. These hormones thin the lining of the uterus, which can help reduce period bleeding in females who experience heavy bleeding.

What is Natazia (estradiol valerate / dienogest) used for?

  • To prevent pregnancy
  • Heavy period bleeding not due to infection, bleeding problems, or other specific health conditions

What are the risks and warnings for Natazia (estradiol valerate / dienogest)?

Natazia (estradiol valerate / dienogest) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options

Cigarette smoking and serious heart problems

  • Risk factors: Females over 35 years old who smoke cigarettes

Warning Icon If you smoke cigarettes, using combined oral contraceptives (COCs), like Natazia (estradiol valerate / dienogest), raises your risk for serious health problems, such as strokes, heart attacks, and blood clots. Females age 35 years and older who smoke are at even higher risk for these problems. If you smoke, talk with your provider about safer birth control alternatives.

Blood clots and strokes

  • Risk factors: Females over 35 years old who smoke | Females over 40 years old who don't smoke | Recent surgery with a long period of bed rest | Starting Natazia (estradiol valerate / dienogest) less than a month after childbirth | High blood pressure | People identified as obese | High cholesterol | Diabetes | Higher dose of estrogen

Natazia (estradiol valerate / dienogest) raises your risk of blood clots. These clots can occur anywhere in your body, including your lungs (pulmonary embolism or PE), legs (deep vein thrombosis or DVT), brain (stroke), and heart (heart attack). Get emergency help right away if you have any signs of a blood clot:

  • Brain: weakness or numbness in your arms, legs, or face on one side of the body, trouble speaking, blurred vision, dizziness, loss of balance, trouble walking, or confusion
  • Eyes: trouble seeing, bulging eye, double vision
  • Heart: chest pain, sweating, nausea, or dizziness
  • Lungs: trouble breathing, chest pain, or cough
  • Legs: cramps, swelling, pain, or muscle tightness

If you need to have surgery, tell your provider you're taking Natazia (estradiol valerate / dienogest). They might have you stop taking it 4 weeks before until 2 weeks after your surgery to lower your risk of blood clots.

Risk of breast and cervical cancer

  • Risk factors: History of breast cancer | Taking COCs for a long time

Study results are mixed, but there's a possibility that Natazia (estradiol valerate / dienogest) and other COCs can raise your risk for breast and cervical cancer.

Don't use Natazia (estradiol valerate / dienogest) if you have breast cancer because some types of breast cancer grow faster in the presence of estrogen, an ingredient in this birth control pill. To help with early breast cancer detection, you can do monthly breast self-checks at home and yearly breast exams with your healthcare provider. Call your healthcare provider if you notice any abnormal changes or feel lumps, pain, or swelling in your breasts.

Get medical help right away if you experience abnormal vaginal bleeding, discharge, or pain during sex, since these could be signs of cervical cancer.

Liver problems

  • Risk factors: Liver problems or infection in the liver | Taking COCs with 50 mcg of estrogen or higher

Though rare, Natazia (estradiol valerate / dienogest) can cause liver problems, such as liver damage and liver tumors. These problems are linked more with earlier formulations of COCs that contained higher levels of estrogen (50 mcg or higher). Call your provider right away if you experience symptoms of liver problems, such as tiredness, stomach pain, or yellowing of the skin or whites of the eyes.

High blood pressure

  • Risk factors: High blood pressure | Older age | Using COCs for a long time | Kidney problems

Natazia (estradiol valerate / dienogest) and other COCs can raise your blood pressure. Your provider might ask you to check your blood pressure regularly. If you notice your blood pressure is higher while you're taking this medication, contact your provider. If you have uncontrolled high blood pressure, Natazia (estradiol valerate / dienogest) might not be the best option for you.

High blood sugar and triglycerides

  • Risk factors: Prediabetes or diabetes | Personal or family history of high triglycerides

COCs like Natazia (estradiol valerate / dienogest) might raise your blood sugar and triglyceride (fat) levels. If you have diabetes, let your provider know if you experience any changes in your blood sugar. A rise in triglycerides can lead to serious conditions like inflammation of the pancreas (pancreatitis). Get emergency medical help if you notice symptoms of pancreatitis, which can include stomach pain, nausea, or vomiting.

Depression

  • Risk factors: History of depression

Let your provider know if you experience symptoms of depression or worsening depression while taking Natazia (estradiol valerate / dienogest). In cases of serious depression, your provider might have you stop taking it.

Interactions with other medications

Certain medications can make Natazia (estradiol valerate / dienogest) get broken down faster in your body, which can make Natazia (estradiol valerate / dienogest) work less well and lead to pregnancy. Some examples include carbamazepine (Tegretol), phenytoin (Dilantin), rifampicin, and St. John’s wort. You shouldn't take Natazia (estradiol valerate / dienogest) for at least 28 days after stopping any of these medications, since it might not work as well for you until after this time. Make sure to tell your provider or pharmacist all of your medications so they can make sure they don't interact with Natazia (estradiol valerate / dienogest).

Worsening of other health conditions

  • Risk factors: History of hereditary angioedema | History of chloasma gravidarum

If you have certain conditions, such as hereditary angioedema or chloasma (a skin condition that causes brown patches on the face), talk to your healthcare provider before taking Natazia (estradiol valerate / dienogest) because it might worsen your symptoms. If you have a history of chloasma, avoid exposure to the sun or UV light while taking COCs like Natazia (estradiol valerate / dienogest).
