Directions
Follow the instructions that come with your NuvaRing prescription and read the information leaflets. If you have any concerns or questions about your prescription, reach out to your doctor or pharmacist.
NuvaRing is a vaginal ring made of a polymer. Each ring consists of 11.7 mg of etonogestrel and 2.7 mg of ethinyl estradiol, releasing approximately 0.12 mg of etonogestrel and 0.015 mg of ethinyl estradiol per day.
Choose a position that's comfortable for you. Squeeze the ring and insert it into the vagina. You may insert the ring using the applicator for NuvaRing instead. The ring should be kept in place for three weeks. At the beginning of the fourth week, remove the ring and leave it out for one week. After removal, place the ring in a foil pouch and dispose of it properly. Keep it away from children and pets. Do not flush the ring. Leave it out for one week. A new NuvaRing should be inserted one week after the last ring was removed, even if you are experiencing menstrual bleeding.
