A small, thin, hormonal contraceptive that is implanted under the skin and effective for up to three years. It was approved in July, 2006 by the U.S. Food and Drug Administration.
Similar to Depo-provera, except instead of mega doses of hormones every 3 months, you get a small dose every day. Supposed to cause less side effects than depo. Supposedly the most effective birth control aside from pure abstinence.
Discreet, you can feel it after it's been implanted, but can't see it.
She didn't want any babies so she used Implanon, it's working great so far.
