Yaz is a brand-name birth control pill prescribed to prevent pregnancy. Yaz is known as a combined oral contraceptive pill (COCP) since it combines an estrogen hormone (ethinyl estradiol) and a progestin hormone (drospirenone), which work together to stop a woman’s ovaries from releasing an egg each month.
While the primary effect of combination birth control pills is to prevent ovulation, the medication can also thicken cervical mucus, making it more difficult for sperm to enter the uterus and fertilize an egg. It can also treat acne and premenstrual dysphoric disorder (PMDD), a more severe form of premenstrual syndrome (PMS) that often results in severe emotional and physical symptoms.
Yaz is available via prescription from a licensed health care provider. Drospirenone ethinyl-estradiol is also available in generic form via prescription. Yaz comes in the form of a tablet to be taken by mouth.
