Nuvaring

List of products in the National Drug Code with proprietary name nuvaring. This product is a vaginal ring containing combination hormone medication and is used to prevent pregnancy. It contains 2 hormones: a progestin (etonogestrel) and an estrogen (ethinyl estradiol). It works mainly by preventing the release of an egg (ovulation) during your menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg. If a fertilized egg does not attach to the uterus, it passes out of the body. Using this product does not protect you or your partner against sexually transmitted diseases (such as HIV, gonorrhea, chlamydia).
