Implanon is a new implantable, progestin-only contraceptive which was approved in the United States in July 2006. Implanon is comprised of a single ethylene vinylacetate copolymer rod that is 4 cm long and 2 mm in diameter. It is inserted subdermally in the groove between the biceps and triceps of the nondominant arm. A literature review was conducted and side effects are discussed. Implanon offers promise as a high-efficacy, long-term contraceptive and can enhance the contraceptive options offered by the women's health care providers. Clinical trial data indicate that the device is both safe and effective.
