Gynecology >> Implanon


IMPLANON is a small, thin, implantable hormonal contraceptive that is effective for up to three years. It was approved in July, 2006 by the U.S. Food and Drug Administration.

IMPLANON prevents pregnancy in several ways. The most important way is by stopping release of an egg from your ovary. IMPLANON also changes the mucus in your cervix and this change may keep sperm from reaching the egg. Also, IMPLANON changes the lining of your uterus.

How Ddoes IMPLANONĀ® Work?

IMPLANON is a flexible plastic rod the size of a matchstick that is put under the skin of your arm.

IMPLANON contains a hormone called etonogestrel. You can use a single IMPLANON rod for up to three years. Because IMPLANON does not contain estrogen, IMPLANON may be for you even if you cannot use estrogen.

If IMPLANON is inserted correctly, your chance of getting pregnant is very low (less than one pregnancy per 100 women who use IMPLANON for one year). IMPLANON must be removed by the end of the third year and may be replaced with a new IMPLANON. It is not known if IMPLANON is as effective in very overweight women because clinical studies did not include many overweight women. Certain medicines may make IMPLANON less effective, and you may also need to use a barrier method of contraception while you are using these medicines.
