When This Medicine Should Not Be Used

How to Use This Medicine

Insert

  • 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 should be left in place for 3 weeks. It will then be removed and another one will be inserted 1 week later. During the week without the ring, you will usually have your menstrual period.
  • 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.
  • Once the ring is in place, you should not be able to feel it. If you feel uncomfortable, the ring may not be inserted far enough. Gently push the ring farther into your vagina. If you feel pain, talk to your doctor.
  • Check for the presence of the ring inside your vagina regularly (including before and after having sex).
  • The ring may move down accidently. This can happen if you are having a bowel movement. Gently push the ring back into place. If the ring comes all the way out, rinse it with warm water and put it back in. Call your doctor if the ring comes out several times.
  • 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 this medicine at room temperature, away from heat and direct light for up to 4 months. Place the used vaginal ring in the re-sealable foil pouch and throw it in the trash. Do not flush the ring down the toilet.
