Yaz is a combination birth control pill that contains the hormones estrogen and progestin. It is used to prevent pregnancy. Yaz is also used to treat premenstrual dysphoric disorder (PMDD) and acne in women who are at least 14 years old and have started having periods. Yaz is not for use by men or boys.
Yaz may cause serious side effects, including:
– Blood clots (deep vein thrombosis/pulmonary embolus), which can lead to death. Yaz may increase your risk of blood clots 4 to 7 times more than birth control pills that do not contain drospirenone.
Yaz is available in three different strengths: Yaz 24, Yaz 28, and Gianvi 28. The Yaz 24 and Yaz 28 are active for 24 days followed by 4 days of inactive pills. Gianvi 28 is active for 28 days with no inactive pills. Yaz and Gianvi are both taken once daily, with or without food.
Yaz should be taken at the same time each day. If you miss a pill, take it as soon as you remember and continue with your regular schedule. If you miss two pills in a row, take two pills on the day you remember and two pills the next day.
How it works
Yaz works by preventing ovulation (the release of an egg from the ovary). It also thickens cervical mucus, which makes it difficult for sperm to reach the egg. Yaz may also help to treat acne by reducing inflammation and decreasing the amount of sebum (oil) produced by the skin.
