This product is a small, thin plastic rod that is inserted under the skin to prevent pregnancy. The rod slowly releases etonogestrel into the body over a 3-year period. Etonogestrel is similar to a natural hormone made in your body. This product does not contain any estrogen.

This medication may not work as well in women who are very overweight or those taking certain drugs. (See also Drug Interactions section.) Discuss your birth control options with your doctor.

Using this medication does not protect you or your partner against sexually transmitted diseases (such as HIV, gonorrhea, chlamydia).

Read the Patient Information Leaflet provided by your pharmacist or health care provider before the rod is placed. If you have any questions, ask your doctor or pharmacist.

Ask your doctor about the best time to schedule your appointment to have the rod placed. Your doctor may want you to have a pregnancy test first. The medication usually starts working right away when the rod is inserted during the first 5 days of your period. If your appointment is at another time in your menstrual cycle, you may need to use a non-hormonal form of birth control (such as condoms, diaphragm, spermicide) for the first 7 days after the rod is placed. Ask your doctor about whether you need backup birth control.

The rod will be inserted under the skin in your upper arm by a health care professional. Usually it will be placed in the arm that you do not write with. Be sure you can feel the rod underneath your skin after it has been placed. If at any time you cannot feel the rod underneath the skin or feel that the rod has been bent or broken, tell your doctor right away.

There will be 2 bandages covering the area where the rod is placed. Leave the top bandage on for 24 hours. Keep the smaller bandage on as directed by your doctor, usually for 3 to 5 days. Keep the bandage clean and dry.

The rod must be removed after 3 years and can be replaced if continued birth control is desired. The rod can be removed at any time by a trained health care professional if birth control is no longer desired or if there are side effects.

Nausea, stomach cramping/bloating, dizziness, headache, breast tenderness, acne, hair loss, weight gain, and vaginal irritation/discharge may occur. Pain, bruising, numbness, infection, and scarring may occur at the site where the rod is placed. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Your periods may be early or late, shorter or longer, heavier or lighter than normal. You may also have some spotting between periods, especially during the first several months of use. If bleeding is prolonged (more than 8 days) or unusually heavy, contact your doctor. If you miss 2 periods in a row, contact your doctor for a pregnancy test.

Some drugs may cause hormonal birth control to work less well by decreasing the amount of birth control hormones in your body. This effect can result in pregnancy. Examples include griseofulvin, modafinil, rifamycins (such as rifampin, rifabutin), ritonavir, St. John's wort, drugs used to treat seizures (such as barbiturates, carbamazepine, felbamate, phenytoin, primidone, topiramate), HIV drugs (such as nelfinavir, nevirapine), among others.

Tell your doctor when you start any new drug, and discuss if you should use reliable backup birth control. Also tell your doctor if you have any new spotting or breakthrough bleeding, because these may be signs that your birth control is not working well.

This medication may interfere with certain lab tests (such as sex-hormone-binding globulin, thyroid), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
