NuvaRing (vaginal ring)

NuvaRing is a hormonal birth control (contraceptive) device for women. It's a flexible, transparent plastic ring that's inserted into the vagina. You wear NuvaRing for three weeks, and then remove it - allowing menstruation to occur - and then insert a new ring after a week.Similar to combination birth control pills, NuvaRing prevents pregnancy by releasing hormones into your body. NuvaRing suppresses ovulation - keeping your ovaries from releasing an egg. NuvaRing also thickens cervical mucus to keep sperm from reaching the egg.NuvaRing is the only vaginal hormonal contraceptive that's approved by the Food and Drug Administration and available in the U.S. To use NuvaRing, you'll need a prescription from your health care provider.
