Implanon, made by Organon International, is a single-rod long acting reversible hormonal contraceptive subdermal implant that is inserted just under the skin of a woman's upper arm. The 4 cm by 2 mm Implanon rod contains 68 milligrams of etonogestrel (a progestin) which is released over a three year period. Because of cases of incorrect insertion by medical personnel in the UK, Implanon will be replaced by Nexplanon, which has a pre-loaded applicator for easier insertion.
