Implanon is a matchstick-size slender rod 1У2 inches long. It is inserted under the skin of the upper arm and releases contraceptive hormones. Implanon had been sold in more than 30 countries since 1998 before it was approved by the FDA in 2006 for use in the United States (Bridges, 2006). In developing countries, long – acting methods play a critical role in providing effective contraception, and efforts to reduce its cost and expand awareness of the method are essential for more widespread use (Neukom et al., 2011; Tumlinson et al., 2011).
How the Implant Works
Implanon releases a slow, steady dose of progestin, and it prevents pregnancy in the same ways as the progestin-only minipill. It may not be effective for women more than 30% heavier than their medically ideal weight.
How to Use the Implant
A medical practitioner inserts the rod in a quick surgical procedure that requires only a local anesthetic. It is effective for up to 3 years, and fertility usually returns quickly after removal of the device (Graesslin & Korver, 2008).
