How YAZ works

When taken as directed, YAZ® (drospirenone & ethinyl estradiol) is 99% effective at preventing pregnancy.

Birth control pills work in 3 ways:

  • Birth control pills "trick" the body into thinking it is pregnant. This prevents the release of an egg (ovulation). Without an egg to be fertilized, you can't become pregnant
  • The cervical mucus is thickened, making it hard for sperm to travel toward the egg and fertilize it, in case an egg is released
  • The lining of the uterus (endometrium) is altered in a way that reduces the likelihood of implantation of the egg

You should know that YAZ has additional indications beyond contraception:

  • For women who choose YAZ for birth control, YAZ is proven to treat the emotional and physical symptoms of premenstrual dysphoric disorder (PMDD), that are severe enough to impact a woman's life. YAZ has not been shown to be effective for the treatment of premenstrual syndrome (PMS), a less serious cluster of symptoms occurring before menstruation. If you or your healthcare provider believes you have PMS, you should only take YAZ if you want to prevent pregnancy; and not for the treatment of PMS.
  • In women who choose an oral contraceptive for birth control, YAZ is proven to help treat moderate acne

Additionally, YAZ, like other pills, can help give you shorter, lighter periods, a more regular cycle, and can even reduce cramps.

YAZ contains a different kind of hormone, drsp, which for some may increase potassium too much. Therefore, you should not take YAZ if you have kidney, liver, or adrenal disease, because this could cause serious heart and health problems.

Tell your healthcare provider if you are on daily long-term treatment for a chronic condition such as cardiovascular disease or chronic inflammatory disease. Women who take certain drugs (see Safety Information) should have their potassium level checked in the first month of taking YAZ.



What is YAZ Prescribed For? YAZ® (drospirenone & ethinyl estradiol) is indicated for:

  • The prevention of pregnancy in women who elect to use an oral contraceptive.
  • Treatment of the emotional and physical symptoms of premenstrual dysphoric disorder (PMDD) in women who choose to use an oral contraceptive as their method of contraception.
  • The effectiveness of YAZ for PMDD when used for more than 3 menstrual cycles has not been evaluated. YAZ has not been evaluated for the treatment of premenstrual syndrome (PMS).
  • Treatment of moderate acne vulgaris
  • In women at least 14 years of age, who have no known contraindications to oral contraceptive therapy and have achieved menarche. YAZ should be used for the treatment of moderate acne only if the patient desires an oral contraceptive for birth control.

Who Shouldn't Take Any Oral Contraceptives (OCs)? Some women should not use OCs, including women who have blood clots, certain cancers, a history of heart attack or stroke, as well as those who are or may be pregnant.

In Addition, Who Shouldn't Take YAZ? YAZ contains drsp®, a different kind of hormone that for some may increase potassium too much. Therefore, you should not take YAZ if you have kidney, liver, or adrenal disease because this could cause serious heart and health problems. Tell your doctor if you are on daily long-term treatment for a chronic condition such as cardiovascular disease or chronic inflammatory disease. Women who take certain drugs (see below) should have their potassium levels checked in the first month of taking YAZ.

What Drugs May Increase Potassium? NSAIDs-ibuprofen (Motrin®, Advil®), naproxen (Naprosyn®, Aleve®, and others) when taken long-term and daily for arthritis or other diseases or conditions, Potassium-sparing diuretics (spironolactone and others), Potassium supplementation, ACE inhibitors (Capoten®, Vasotec®, Zestril®, and others), angiotensin-II receptor antagonists (Cozaar®, Diovan®, Avapro®, and others), aldosterone antagonists, and heparin.

What Are The Risks Involved With Taking Any Oral Contraceptive (OC)? OCs can be associated with an increased risk of several serious cardiovascular side effects, including blood clots, stroke, and heart attack. Women, especially those 35 and over, are strongly advised not to smoke because it increases these risks. OCs do not protect against HIV infection or other STDs.
