title: Etonogestrel implant (Implanon) for contraception.
abstract: Levonorgestrel 38 mg subdermal implant (Norplant), intended to provide contraception for 5 years, was withdrawn in the UK in 1999 due to unwanted effects (menstrual disturbances) and difficulties in removing the device. Since then, [symbol: see text]etonogestrel implant (Implanon-Organon), another progestogen--only subdermal contraceptive device, has become available in the UK. The manufacturer claims that etonogestrel implant provides contraception for up to 3 years and is easy to insert and remove. Here, we consider the place of etonogestrel implant.
