Insert the ring into your vagina as directed. Follow the directions on the prescription label. The ring will remain place for 3 weeks and is then removed for a 1-week break. A new ring is inserted 1 week after the last ring was removed, on the same day of the week. Check often to make sure the ring is still in place. If the ring was out of the vagina for an unknown amount of time, you may not be protected from pregnancy. Perform a pregnancy test and call your care team. Do not use more often than directed.
A patient package insert for the product will be given with each prescription and refill. Read this sheet carefully each time. The sheet may change frequently.
Contact your care team regarding the use of this medication in children. Special care may be needed.
What if I miss a dose?
You will need to use the ring exactly as directed. It is very important to follow the schedule every cycle. If you do not use the ring as directed, you may not be protected from pregnancy. If the ring should slip out, is lost, or if you leave it in longer or shorter than you should, contact your care team for advice.

What should I watch for while using this medication?
Visit your care team for regular checks on your progress. You will need a regular breast and pelvic exam and Pap smear while on this medication.
Check with your care team to see if you need an additional method of contraception during the first cycle that you use this ring. Male condoms (made with natural rubber latex, polyisoprene, and polyurethane) and spermicides may be used. Do not use a diaphragm, cervical cap, or a female condom, as the ring can interfere with these birth control methods and their proper placement.
If you have any reason to think you are pregnant, stop using this medication right away and contact your care team.
If you are using this medication for hormone related problems, it may take several cycles of use to see improvement in your condition.
Smoking tobacco increases the risk of getting a blood clot or having a stroke while you are taking this medication, especially if you are older than 35 years.
You may get dark patches on your face (chloasma) while taking this medication. If you noticed dark patches on your face during a pregnancy, your risk of getting it is higher. Keep out of the sun. If you cannot avoid the sun, wear protective clothing and use sunscreen. Do not use sun lamps, tanning beds, or tanning booths.
This medication can make your body retain fluid, making your fingers, hands, or ankles swell. Your blood pressure can go up. Contact your care team if you feel you are retaining fluid.
If you are going to have elective surgery, you may need to stop using this medication before the surgery. Consult your care team for advice.
Using this medication does not protect you or your partner against HIV or other sexually transmitted infections (STIs).
