YAZ Tablet contains a combination of Ethinyl Estradiol (0.02 mg) and Drospirenone (3 mg), which are synthetic hormones used primarily for oral contraception. Ethinyl Estradiol is a synthetic estrogen, while Drospirenone is a synthetic progestin with anti-mineralocorticoid and anti-androgenic properties. This combination works by inhibiting ovulation, altering the cervical mucus to prevent sperm penetration, and modifying the endometrial lining to reduce the likelihood of implantation. YAZ is indicated for the prevention of pregnancy in women of reproductive age. Additionally, it may be prescribed for the treatment of moderate acne vulgaris in women who desire oral contraception and for the management of premenstrual dysphoric disorder (PMDD). The tablet should be taken once daily, preferably at the same time each day, to maximize efficacy. Patients should be counseled on the importance of adherence to dosing schedules and informed about potential side effects, which may include nausea, headache, breast tenderness, and changes in menstrual bleeding patterns. Contraindications include a history of thromboembolic disorders, uncontrolled hypertension, liver disease, and known or suspected pregnancy. Regular medical evaluation is recommended to monitor for adverse effects and ensure safe use.
