Prevention of pregnancy in women of reproductive age. Not indicated for emergency contraception.
The ring releases ethinyl estradiol and etonogestrel, which suppress ovulation, thicken cervical mucus to impede sperm movement, and thin the uterine lining to reduce implantation chances.
Requires a new ring every 3 weeks with a 1-week ring-free period. Contraindicated in women over 35 who smoke, those with history of blood clots, stroke, or certain cancers. Users should check for the ring monthly and avoid use during pregnancy. Common side effects may include headache, nausea, breast tenderness, and mood changes.
