What is etonogestrel (Implanon)?
Etonogestrel is the active ingredient in Implanon, a brand-name birth control device used to prevent pregnancy. This specific form of contraception is administered via a small, flexible plastic rod (about the size of a match) inserted into the upper arm's skin.
It is important to note that while contraceptives such as etonogestrel offer significant benefits, they do not protect against sexually transmitted infections (STIs). Talk to your doctor about your health history and any medication you are currently taking before you receive a birth control implant.
