    • What is this medication and its most common uses?

      Yaz is a birth control pill used to prevent pregnancy. Yaz is also used to treat acne (pimples) in women ≥14 years old, who have started having menstrual periods, and want to use the pill for birth control. Yaz is also used to treat premenstrual dysphoric disorder (PMDD) (a severe condition that consists of physical and emotional symptoms, such as depression and irritability, before menstruation) in women who choose to use Yaz for birth control.

    • What should I know when beginning and continuing on this medication?

      How does this medication work?

      Yaz delivers hormones to block ovulation. If ovulation does not occur, your egg is not released, thereby preventing you from becoming pregnant. By adjusting hormone levels in your body, Yaz also helps control acne and the physical and emotional symptoms associated with PMDD.

      What are the beneficial effects of this medication and when should I begin to have results?

      What:

      Birth Control: When Yaz is taken correctly without missing any pills, the chance of becoming pregnant is approximately 1 to 2 in 100 women per year.

      Acne: Yaz has also been shown to improve the appearance of your acne.

      PMDD: Yaz has also been shown to improve the physical and emotional symptoms associated with your PMDD.

      When: 

      Birth Control: The effects of pregnancy prevention are different depending on the day you start your first pack of pills. If you start on Sunday, then it may take 7 days for the pills to take effect (and you should therefore use another method of birth control during this time). If you start on the first day of your period, the pill should be effective right away, and you therefore will not need a back-up method of birth control.

      Acne and PMDD: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. It is important that you take Yaz exactly as your healthcare provider has prescribed.

      How do I know it is working?

      If you are taking the pill as directed by your healthcare provider and not missing any doses, you should be protected from becoming pregnant. You may also notice an improvement in the appearance of your acne and an improvement in the way you feel.

       

    • What are the possible side effects of this medication?

      The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.

      Cigarette smoking increases the risk of serious heart-related side effects from use of birth control pills. This risk increases with age (especially if you are >35 years old) and heavy smoking. Do not smoke while you are taking birth control pills.

      Birth Control and Acne

      More common side effects may include: headache/migraine, menstrual irregularities, nausea, vomiting, breast pain and tenderness, mood changes.

      PMDD

      More common side effects may include: spotting or bleeding between menstrual periods, nausea, headache, breast tenderness.

      Less common side effects for Yaz may include: acne, less sexual desire, bloating or fluid retention, blotchy darkening of the skin (especially on the face), high blood sugar levels, high fat levels in the blood, depression, problems tolerating contact lenses, weight changes.

      Blood clots are one of the most serious side effects of taking birth control pills. Blood clots can occur in your legs, lungs, or eyes. Call your healthcare provider right away if you experience sharp chest pain, coughing up blood, sudden shortness of breath, pain in your calf, or sudden partial or complete loss of vision, as these may be signs of a possible blood clot.

      Birth control pills may increase your risk of developing a stroke, angina (chest pain), or a heart attack. Smoking greatly increases the possibility of suffering a heart attack or stroke. Call your healthcare provider right away if you develop crushing chest pain or heaviness in your chest, sudden severe headache or vomiting, dizziness or fainting, changes in your vision or speech, weakness, or numbness in an arm or leg, as these may be signs of a possible heart attack or stroke.

      Birth control pills increase your risk of developing gallbladder disease.

      Birth control pills can cause noncancerous but dangerous liver tumors. These tumors can rupture and cause life-threatening internal bleeding. Call your healthcare provider right away if you experience severe pain or tenderness in your stomach area, or yellowing of your skin or the whites of your eyes, often accompanied by fever, fatigue, loss of appetite, dark-colored urine, or light-colored bowel movements, as these may be signs of a possibly ruptured liver tumor or other liver problems.

      Birth control pills can slightly increase your chance of developing breast cancer. You should have regular breast examinations by your healthcare provider and examine your own breasts monthly. Call your healthcare provider right away if you feel a lump when you are examining your breasts. Tell your healthcare provider if you have a family history of breast cancer.

      Irregular vaginal bleeding or spotting may occur while you are taking the pills. Irregular bleeding may vary from slight staining between menstrual periods to breakthrough bleeding, which is a flow much like a regular period. Irregular bleeding occurs most often during the first few months of taking the pills, but may also occur after you have been taking the pill for some time. Such bleeding may be temporary and usually does not indicate any serious problems. It is important to continue taking your pills on schedule. Tell your healthcare provider if the bleeding occurs in more than one cycle or lasts for more than a few days.

      Birth control pills can cause an increase in your blood pressure and blood potassium levels.

      There may be times when you may not have regular menstrual periods after you have completed taking a cycle of pills. If you have taken your pills regularly and miss one menstrual period, continue taking your pills for the next cycle, but be sure to inform your healthcare provider. If you have not taken the pills daily as instructed and missed a menstrual period, or if you missed two consecutive menstrual periods, you may be pregnant.

       

    • Who should not take this medication?

      Do not take Yaz if you are allergic to it or any of its ingredients.

      Do not take Yaz if you have a history of heart attack or stroke; heart disease; blood clots in your legs, lungs, or eyes; breast cancer or cancer of the lining of the uterus, cervix, or vagina; unexplained vaginal bleeding (until a diagnosis is reached by your healthcare provider); liver tumors or active liver disease; kidney disease; high blood pressure uncontrolled by medication; diabetes with kidney, eye, nerve, or blood vessel damage; certain types of headaches; or adrenal insufficiency (a disorder where the body does not make enough of certain hormones).

      Do not take Yaz if you are or think you may be pregnant.

       

    • What should I tell my healthcare provider before I take the first dose of this medication?

      Tell your healthcare provider about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Yaz. Tell your healthcare provider if you have ever had any of the health conditions listed above. Also, talk to your healthcare provider about your complete medical history, especially if you have or have had breast cancer; high blood potassium levels; diabetes; high cholesterol or triglyceride (fats in your blood) levels; high blood pressure; migraines or other headaches; seizures; depression; gallbladder, liver, heart, or kidney disease; irregular menstrual periods; or if you plan to have surgery.

    • What is the usual dosage?

      The information below is based on the dosage guidelines your healthcare provider uses. Depending on your condition and medical history, your healthcare provider may prescribe a different regimen. Do not change the dosage or stop taking your medication without your healthcare provider's approval.

      Women and adolescents who have had their first menstrual period: There are 24 light-pink "active" pills, and 4 white "reminder" pills in the pill pack.

      Sunday Start: Take the first light-pink "active" pill of the first pack on the Sunday after your period begins, even if you are still bleeding. If your period begins on a Sunday, start the pack that same day. Take one light-pink "active" pill per day for 24 days followed by one white "reminder" pill per day for 4 days. After all 28 pills have been taken, start a new course the next day (Sunday).

      Day 1 Start: Take the first light-pink "active" pill of the first pack during the first 24 hours of your period. Take one light-pink "active" pill per day from the 1st day through the 24th day of the menstrual cycle (counting the day your period starts as Day 1), followed by one white "reminder" pill per day for 4 days. Take the pills without interruption for 28 days. After all 28 pills have been taken, start a new course the next day.

       

    • How should I take this medication?

      Before you start taking your pills, be sure to read the directions. Take one pill at the same time every day until the pack is empty. You may take Yaz with or without meals. It is preferable to take the pill after the evening meal or at bedtime, with some liquid, as needed.

      When you finish a pack, start the next pack on the day after your last white "reminder" pill. Do not wait any days between packs. If you are switching from another brand of pills, start Yaz on the same day that a new pack of the previous pills should have been started. If you are switching from another birth control method, talk to your healthcare provider about what you should do.

      For the first cycle of a Sunday Start regimen, use another method of birth control (such as condoms or spermicide) as a back-up method if you have sex anytime from the Sunday you start your first pack until the next Sunday (7 days).

      You will not need to use a back-up method of birth control for the first cycle of a Day 1 Start regimen, since you are starting the pill at the beginning of your period.

      If you vomit within 3 to 4 hours after you take a pill, please refer to the "What should I do if I miss a dose of this medication?" section or call your healthcare provider.

       

    • What should I avoid while taking this medication?

      Do not smoke cigarettes while you are taking Yaz.

      Do not skip pills, even if you are spotting or bleeding between monthly periods, feel sick to your stomach (nausea), or if you do not have sex very often.

       

    • What are the possible food and drug interactions associated with this medication?

    • May I receive this medication if I am pregnant or breastfeeding?

    • What should I do if I miss a dose of this medication?

      If you miss one light-pink "active" pill, take it as soon as you remember. Take the next pill at your regular time. This means you can take two pills in one day. You do not need a back-up birth control method if you have sex.

      If you miss two or more light-pink "active" pills, consult the patient information that accompanied your prescription or call your pharmacist for advice.

      If you miss any of the 4 white "reminder" pills, throw away the missed pills. Keep taking the scheduled pills until the pack is finished. You do not need a back-up method of birth control.
