Implanon (contraceptive implant)
Implanon (contraceptive implant)
Implanon is a contraceptive implant for women that's placed under the skin of the upper arm. Implanon releases a low, steady dose of the hormone progestin to thicken cervical mucus and thin the lining of the uterus (endometrium) — preventing sperm from reaching the egg. Implanon typically suppresses ovulation as well.
Implanon is the only contraceptive implant that has Food and Drug Administration (FDA) approval and is sold in the U.S.
Implanon prevents pregnancy for up to three years after insertion. Implanon doesn't offer protection from sexually transmitted infections (STIs).

Why it's done
Implanon offers effective, long-term contraception. Among various benefits, Implanon:
Implanon isn't appropriate for everyone, however. Your health care provider may discourage use of Implanon if you:
In addition, tell your health care provider if you have a history of:
Risks associated with Implanon include:
Implanon doesn't offer protection from sexually transmitted infections (STIs).
An estimated 1 out of 100 women who use Implanon for one year will get pregnant. If you do conceive while using Implanon, there's a higher chance that the pregnancy will be ectopic — when the fertilized egg implants outside the uterus, usually in a fallopian tube.
How you prepare
Your health care provider will evaluate your overall health and do a pelvic exam before inserting Implanon. He or she will determine the appropriate timing for the insertion of Implanon based on your menstrual cycle and your previous birth control method. You may need to take a pregnancy test and use a nonhormonal backup method of contraception for one week.
A backup method of contraception may not be necessary if you previously:
What you can expect
Implanon insertion is typically done in a health care provider's office. The actual procedure takes about one minute, though preparation will take about 15 minutes.
During the procedure
After the procedure
It's common to experience some degree of bruising, pain, scarring or bleeding at the insertion site.
Contact your health care provider if you:
Use of progestins is associated with a risk of blood clots and heart attacks. However, estrogen has been shown to promote blood clots when given alone, and most contraceptive methods contain estrogen and progestin. Many experts believe progestin-only contraceptive methods carry significantly lower risks of these types of complications than do contraceptive methods that contain estrogen and progestin.
Remember, Implanon can prevent pregnancy for up to three years. The device must be removed and replaced at the three-year point to continue offering pregnancy protection.
Your health care provider may recommend removing Implanon earlier if you:
To remove the device, your health care provider will inject a local anesthetic in your arm beneath the device and make a small incision in your skin. He or she will push the device toward the incision until the tip is visible and the device can be pulled out with forceps. Your health care provider will then close the incision and apply a pressure bandage. Implanon removal typically takes less than five minutes. If you choose, a new device can be implanted as soon as the original device is removed. Be prepared to use another type of contraception right away if you don't have a new device inserted.
