WARNING: Do not use this medication if you smoke cigarettes/use tobacco and are over 35 years old. Smoking raises your risk of stroke, heart attack, blood clots, and high blood pressure from hormonal birth control (such as the pill, patch, ring). The risk of these serious problems increases with age and with the number of cigarettes you smoke. Do not smoke or use tobacco.
USES: 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).
HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start using this product and each time you get a refill. The leaflet contains very important information on how to properly use and dispose of the vaginal ring. If you have any questions, ask your doctor or pharmacist.This product is for vaginal use only. Before use, wash and dry your hands. Remove the ring from the reclosable foil pouch, keeping the pouch for later disposal of the used ring. Fold the ring in half and gently push it into your vagina as directed, until it feels comfortable. Although some women may be aware of the ring in the vagina, most women do not feel it once it is in place; it will not interfere with sexual intercourse (though your partner may be able to feel the ring). Unlike a diaphragm, the ring's exact position in the vagina does not affect how well it works. Once inserted, keep the ring in place for 3 weeks in a row.If this is the first time you are using the ring, use an additional form of non-hormonal birth control (such as condoms, spermicide) for the first 7 days to prevent pregnancy until the ring has enough time to work. Do not use a diaphragm or cervical cap for additional birth control since the ring may interfere with proper placement. If you start using the ring on the first day of your period, you do not need to use back-up birth control the first week.After using the ring for 3 weeks, remove it on the same day of the week and about the same time that you placed it. Place the used ring back into the foil pouch and discard in the trash. Do not flush the used ring down a toilet. If you have pain/bleeding when trying to remove the ring, or if you cannot remove it, tell your doctor right away.Next, do not wear a ring for 1 week (7 days). You should have your period within 2 to 3 days after the ring is removed. After 1 ring-free week, insert a new ring on the same day of the week that you removed the old ring, whether or not you have your period. If you do not get your period, consult your doctor. Do not go longer than 7 days without a ring. Doing so will increase your risk of pregnancy.The vaginal ring may accidentally fall out during sexual intercourse, during a bowel movement, or while removing a tampon. If this happens, rinse it with cool to lukewarm (not hot) water and re-insert the ring as soon as possible. If the ring has been out longer than 3 hours, or if you are not sure how long it has been out, you could become pregnant. Re-insert it or insert a new ring as directed and use an additional form of non-hormonal birth control (such as condoms, spermicide) for the next 7 days to prevent pregnancy.If you have left the ring in place longer than directed, up to an extra week (4 weeks total), you will still be protected from pregnancy. Remove the ring and insert a new ring after 1 ring-free week. However, if you have left the ring in place longer than 4 weeks, you may not be protected from pregnancy. Remove the ring and contact your doctor for a pregnancy test before inserting a new ring and using additional back-up birth control for 7 days.Rarely, the vaginal ring has broken at the weld joint after placement. This increases the chance of it slipping out of the vagina. If this happens, throw it away and use a new ring.Ask your doctor or pharmacist about how to switch from other forms of hormonal birth control (such as birth control pills) to this product. If any information is unclear, consult the Patient Information Leaflet or your doctor or pharmacist.
SIDE EFFECTS: Vaginal discomfort/irritation, nausea, vomiting, headache, bloating, breast tenderness, swelling of the ankles/feet (fluid retention), or weight change may occur. Vaginal bleeding between periods (spotting) may occur, especially during the first few months of use. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. If you miss 2 periods in a row (or 1 period if the ring has not been used properly), talk to your doctor about a pregnancy test.Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: lumps in the breast, mental/mood changes (such as new/worsening depression), severe stomach/abdominal pain, unusual changes in vaginal bleeding (such as continuous spotting, sudden heavy bleeding, missed periods), dark urine, yellowing eyes/skin.Very rarely, the ring has been accidentally placed into the bladder. Tell your doctor right away if you have urgent/frequent/burning/painful urination and cannot find the ring in your vagina.This medication may rarely cause serious (sometimes fatal) problems from blood clots (such as deep vein thrombosis, heart attack, pulmonary embolism, stroke). Get medical help right away if any of these side effects occur: chest/jaw/left arm pain, confusion, sudden dizziness/fainting, pain/swelling/warmth in the groin/calf, slurred speech, sudden shortness of breath/rapid breathing, unusual headaches (including headaches with vision changes/lack of coordination, worsening of migraines, sudden/very severe headaches), unusual sweating, weakness on one side of the body, vision problems/changes (such as double vision, partial/complete blindness).Rarely, a very serious (possibly fatal) bacterial infection (toxic shock syndrome-TSS) has occurred in women using vaginal rings.

However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects.

Your doctor may need to adjust your diabetes medication, exercise program, or diet.Tell your doctor if you just had or will be having surgery or if you will be confined to a bed or chair for a long time (such as a long plane flight). These conditions increase your risk of getting blood clots, especially if you are using hormonal birth control. You may need to stop this medication for a time or take special precautions.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).The hormones in this product may cause blotchy, dark areas on your skin (melasma). Sunlight may worsen this effect. Avoid prolonged sun exposure, sunlamps, and tanning booths.

Contact your eye doctor if these problems occur.This medication must not be used during pregnancy. If you become pregnant or think you may be pregnant, tell your doctor immediately. If you have just given birth or had a pregnancy loss/abortion after the first 3 months, talk with your doctor about reliable forms of birth control, and find out when it is safe to start using birth control that contains a form of estrogen, such as this medication.The hormones in this product may decrease breast milk production. A small amount passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.
