What is Yaz?
Yaz tablets contain a combination of drospirenone and ethinyl estradiol. Drospirenone and ethinyl estradiol prevent ovulation (the release of an egg from an ovary) and also cause changes in your cervical and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
Yaz is used as contraception to prevent pregnancy. It is also used to treat moderate acne in women who are at least 14 years old and have started having menstrual periods, and who wish to use birth control pills to prevent pregnancy.
Yaz is also used to treat the symptoms of premenstrual dysphoric disorder (PMDD), such as anxiety, depression, irritability, trouble concentrating, lack of energy, sleep or appetite changes, breast tenderness, joint or muscle pain, headache, and weight gain.
Do not use Yaz if you are pregnant or if you have recently had a baby.
You should not take Yaz if you have any of the following conditions: uncontrolled high blood pressure, heart disease, a blood-clotting disorder, circulation problems, diabetic problems with your eyes or kidneys, unusual vaginal bleeding, liver disease or liver cancer, severe migraine headaches, if you smoke and are over 35, or if you have ever had breast or uterine cancer, jaundice caused by birth control pills, a heart attack, a stroke, or a blood clot.
Taking Yaz can increase your risk of blood clots, stroke, or heart attack, especially if you have certain other conditions, or if you are overweight.
Smoking can greatly increase your risk of blood clots, stroke, or heart attack. You should not take Yaz if you smoke and are over 35 years old.
Before taking Yaz
Taking Yaz can increase your risk of blood clots, stroke, or heart attack. You are even more at risk if you have high blood pressure, diabetes, high cholesterol, or if you are overweight. Your risk of stroke or blood clot is highest during your first year of taking birth control pills. Your risk is also high when you restart Yaz after not taking them for 4 weeks or longer.
Smoking can greatly increase your risk of blood clots, stroke, or heart attack. Your risk increases the older you are and the more you smoke. You should not take combination birth control pills if you smoke and are over 35 years old.
Do not use if you are pregnant. Stop taking Yaz and tell your doctor if you become pregnant, or if you miss two menstrual periods in a row. If you have recently had a baby, wait at least 4 weeks before taking Yaz.
You should not take Yaz if you have:
untreated or uncontrolled high blood pressure;
heart disease (coronary artery disease, uncontrolled heart valve disorder, history of heart attack, stroke, or blood clot);
a blood-clotting disorder or circulation problems;
problems with your eyes, kidneys or circulation caused by diabetes;
a history of hormone-related cancer such as breast or uterine cancer;
unusual vaginal bleeding that has not been checked by a doctor;
liver disease, liver cancer, history of jaundice caused by pregnancy or birth control pills; or
severe migraine headaches (with aura, numbness, weakness, or vision changes), especially if you are older than 35.
To make sure Yaz are safe for you, tell your doctor if you have:
high blood pressure, varicose veins;
high cholesterol or triglycerides, or if you are overweight;
an electrolyte imbalance (such as high levels of potassium in your blood);
a history of depression;
diabetes, underactive thyroid, gallbladder disease;
seizures or epilepsy;
a history of fibrocystic breast disease, lumps, nodules, or an abnormal mammogram.
The hormones in Yaz can pass into breast milk and may harm a nursing baby. Yaz may also slow breast milk production. Do not use if you are breast feeding.
How should I take Yaz?
Take Yaz exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. You will take your first pill on the first day of your period or on the first Sunday after your period begins. You may need to use back-up birth control, such as condoms or a spermicide, when you first start using Yaz. Follow your doctor's instructions.
Take one pill at the same time every day i.e. no more than 24 hours apart. When the Yaz pill pack runs out, start a new pack the following day. You may get pregnant if you do not take one pill daily. Get your prescription refilled before you run out of pills completely.
The Yaz-pill pack has 24 light pink pills (with hormones) to be taken for 24 days, followed by 4 white pills (without hormones) to be taken for the next four days.
You may have breakthrough bleeding, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.
Use a back-up birth control if you are sick with severe vomiting or diarrhea.
If you need surgery or medical tests or if you will be on bed rest, you may need to stop using Yaz for a short time. Any doctor or surgeon who treats you should know that you are using Yaz.
While taking Yaz, you will need to visit your doctor regularly.
Store Yaz at room temperature away from moisture and heat.

What other drugs will affect Yaz?
Many drugs can interact with birth control pills and make them less effective, which may result in pregnancy.
