  • Birth Control

    Yaz (drospirenone and ethinyl estradiol) prevents 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.
