Yaz is prescribed for contraception in preventing pregnancy and also for treating moderate acne in young women. PMDD (premenstrual dysphoric disorder) can also be treated with Yaz. The medication works by preventing ovulation by causing changes in the uterine and cervical lining, making it more difficult for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Important information/ precautions

Yaz may cause birth defects. Your doctor must be told immediately if you do become pregnant. The hormones found in Yaz can pass through breast milk and potentially harm a nursing baby. It may also slow down the production of breast milk. Do not use Yaz if breast-feeding.

Do Not Use Yaz If You Have:

  • a history of blood clot or stroke
  • problems with circulatory system
  • uterine or breast cancer
  • heart valve disorder
  • abnormal vaginal bleeding
  • adrenal gland disorder
  • liver or kidney disease
  • extreme high blood pressure
  • history of jaundice due to birth control pills
  • migraine headaches

Reasons to Notify a Physician

Drospirenone found in Yaz may raise the body’s potassium levels. There are other medical conditions that can affect these levels, including kidney disease, liver disease and adrenal gland disorders. Before starting on Yaz, the doctor must be notified of these conditions.

Consult Your Physician If You Have a History with:

  • high blood pressure
  • heart disease
  • high cholesterol
  • liver cancer
  • diabetes
  • epilepsy
  • seizures
  • gallbladder disease
  • history of irregular menstrual cycles or depression

When Taking Yaz

Yaz must be taken exactly as prescribed. The first pill is taken on the first day of your cycle or on the first Sunday following the beginning of your period. One pill will be taken every day and no more 24 hours between each one. When one pack runs out, begin a new pack the next day.

Breakthrough bleeding may occur while on Yaz. Tell the doctor if bleeding continues or happens to be very heavy. If you are having medical tests, surgery or on bed rest, you may have to stop taking Yaz for a little while. Inform any doctor or surgeon when using birth control. While taking Yaz, you need to see a doctor regularly. It is important to perform self-examines on your breasts each month to check for lumps while on Yaz. Yaz must be stored at room temperature and away from heat or moisture.

In Case of Missed Dosage

Missing a dose of Yaz increases the risk of pregnancy. If one ‘active’ pill is missed, take it as soon as possible or take two at your next dose time. There is no need for backup birth control. If two ‘active’ pills are missed in week one or two, take two pills for the next two scheduled doses. You need to use some other type of birth control for the following 7 days.

If two active pills are missed in week three or if three are missed in a row at any time within the first three weeks, throw the incomplete pack away and begin a new pack on the same day if you are a ‘Day 1’ starter. If you start on Sunday, keep taking pills each day until Sunday. On Sunday, through the incomplete pack out and begin a new pack the same day. You may not see a period that month. If you happen to miss your period two months back-to-back, call the doctor to test for pregnancy.

If you happen to miss a reminder pill in week number four, skip it and take the next pill when scheduled.
If a pill is missed, pregnancy may occur if you have intercourse within 7 days after a pill is missed. You must use another method of birth control as backup for one week.

In Case of an Overdose

If you believe you have taken too much Yaz, seek medical attention immediately. Symptoms of overdose may include vomiting, vaginal bleeding and nausea.

What to Avoid While Taking Yaz

Do not smoke when taking Yaz, especially if older than 45. Smoking may increase the risk of stroke, blood clots, or heart attack related to birth control pills.

Yaz does not protect from STDs. A condom is the only way to protect from these diseases.
