Table of contents:

Implanon is a prescription contraceptive medication indicated to prevent pregnancy. It is a flexible plastic rod about the size of a matchstick inserted under the upper arm's skin. Implanon works by slowly releasing a synthetic hormone called etonogestrel into the body over a three-year period.

Etonogestrel is a progestogen hormone that thickens the mucus on the cervix, making it difficult for sperm to reach the egg. It also changes the lining of the uterus, making it less hospitable for the implantation of fertilized eggs.

Implanon slowly releases the hormone into the body over a three-year period and provides highly effective contraception. The medication may not work as well in women who are overweight or obese and may have adverse side effects in some individuals.

Uses and Dosage

To prevent pregnancy, Implanon is a small plastic rod inserted under the skin by a healthcare professional. Etonogestrel is released slowly into the body over a period of three years, which is similar to a hormone produced naturally in your body, and the product does not contain estrogen.

When scheduling your appointment, consult your doctor regarding the best time to have the rod placed. A pregnancy test may be needed, and the medication typically begins working immediately during the first 5 days of your period. If the appointment is at another time in your menstrual cycle, a non-hormonal backup form of birth control may be necessary for the first 7 days after the rod is placed.

Make sure you can feel the rod under your skin after positioning it and notify your doctor if you cannot feel the rod under your skin or if it has been bent or broken. Two bandages will cover the area where the rod is placed, and the top bandage must be kept on for 24 hours. The smaller bandage should be kept for three to five days under your doctor's guidance. Keep your bandage clean and dry.

After three years, the rod must be removed, but it can be replaced if continuous birth control is necessary. A qualified health care provider may remove the rod at any time if birth control is no longer required or in the case of side effects.
