Ethinylestradiol/etonogestrel, sold under the brand name Nuvaring among others, is a hormonal vaginal ring used for birth control and to improve menstrual symptoms.[3] It contains ethinylestradiol, an estrogen, and etonogestrel, a progestin.[4] It is used by insertion into the vagina.[3] Pregnancy occurs in about 0.3% of women with perfect use and 9% of women with typical use.[5]
Common side effects include irregular vaginal bleeding, nausea, sore breasts, vaginitis, mood changes, and headache.[6] Rare but serious side effects may include blood clots, toxic shock syndrome, anaphylaxis, gallstones, and liver problems.[6] Use is not recommended in those who both smoke and are over the age of 35.[6] While use in pregnancy is not recommended, such use has not been found to be harmful to the baby.[6] Use during breastfeeding is typically not recommended as it may decrease the milk supply.[6] It mainly works by decreasing gonadotropins thereby stopping ovulation.[6]
The combination was approved for medical use in the United States in 2001.[4] It is available as a generic medication in the United Kingdom.[3] In 2022, it was the 194th most commonly prescribed medication in the United States, with more than 2 million prescriptions.[7][8]
