Long Term Single-Rod Contraceptive Approved by FDA

Implanon, a single-rod contraceptive implant about the size of a matchstick was approved by the FDA. The implant was designed to prevent conception for up to three years.

This is the first single-rod design to meet FDA’s approval. A six-rod implant designed by Norplant was removed from marketing six years ago, because of side effects. A double-rod implant (Jadelle), was approved by by FDA in 1996, but was never marketed in the US.

The Implanon rod contains 68mg of etonogestrel set for release over a three year period. The implant will continue to release small amounts of etonogestrel after three years, but the affect would be minimal. However, Implanon can be replaced every three years. It is inserted under the skin on the inside of the upper arm.

But if you are apprehensive about minor surgery, or concern about side effects of Implanon, the proper use of condoms is still the most effective way to prevent sexually transmitted diseases.
