When This Medicine Should Not Be Used
How to Use This Medicine
- This medicine is in a ring that is put into your vagina. Your doctor or nurse will show you how to put in the ring. The ring is left in place for 3 weeks then removed and another inserted 1 week later. During the week without the ring, you will usually have your menstrual period. Follow directions about how to use the ring, and ask your doctor if you have questions.
- The first time you start using the ring, you should also use a second form of birth control during the first 7 days to avoid pregnancy. Do not use a diaphragm, because the ring may affect how the diaphragm fits.
- Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
- Missed dose:
- If NuvaRing® has slipped out and it has been out for less than 3 hours, rinse it in cool or lukewarm water and reinsert it. You should still be protected from pregnancy. If NuvaRing® has been out for more than 3 hours, insert a new ring. You must use an extra method of birth control until the NuvaRing® has been in place for 7 days in a row. Do not use a diaphragm.
- If you leave the vaginal ring in place for more than 4 weeks, you may not be protected from pregnancy. Make sure that you are not pregnant before you insert a new ring. You must use an additional form of birth control (not a diaphragm) until the new ring has been in place for 7 days in a row.
- If you forget to insert a new ring after the ring-free week, call your doctor for instructions.
- Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Place the used NuvaRing® in the re-sealable foil pouch and put it in the trash where children and pets cannot get to it. Do not flush the ring down the toilet.
