Yaz (Drospirenone & Ethinylestradiol): Uses, Side Effects & Precautions
Yaz is a combined oral contraceptive pill made of drospirenone and ethinylestradiol. It’s FDA-approved to prevent pregnancy and treat moderate acne and PMDD in users who also want contraception. Here’s what you must know to stay informed and safe.
How Yaz Works
Yaz prevents pregnancy by stopping ovulation, making cervical mucus thicker, and thinning the uterine lining. Its drospirenone component also offers mild anti-androgen and antimineralocorticoid benefits. :contentReference[oaicite:2]{index=2}
