NuvaRing (generic: etonogestrel/ethinyl estradiol) is a prescription vaginal ring used to prevent pregnancy in women. NuvaRing contains two hormones which belong to a group of drugs called hormonal contraceptives. These hormones prevent pregnancy by stopping ovulation and by altering cervical mucus and the lining of the uterus.

This medication comes in the form of a vaginal ring that is inserted vaginally for three weeks, then removed for one week.  This process is repeated each month.

Common side effects of NuvaRing include vaginal infections and irritation, vaginal secretion, headaches, and weight gain.
