Etonogestrel

Brand names: Implanon

Why is Etonogestrel prescribed?

Implanon is a type of birth control for women. It is a flexible plastic rod the size of a matchstick that is put under the skin of your arm. Implanon contains a hormone called etonogestrel. You can use a single Implanon rod for up to 3 years. Because Implanon does not contain estrogen, your doctor may recommend Implanon even if you cannot use estrogen.

If Implanon is not placed properly, it may not prevent pregnancy or it may be difficult or impossible to remove. After you receive Implanon, check that it is in place by pressing your fingertips over the skin in your arm where Implanon was placed. You should be able to feel the Implanon rod.
