How It Works

Nexplanon is a hormonal implant containing progesterone. It is a flexible plastic rod the size of a matchstick that is put under the skin of your arm in an office procedure. Implanon prevents pregnancy primarily by suppressing ovulation or release of the egg from a woman’s ovary.


Implanon is considered 99.95% effective.


  • Highly effective.
  • Ease of use. Once inserted it provides 3 years of birth control without daily attention.
  • Discreet. Does not require contraceptive supplies. In most users the rod is not visible under the skin.
  • No estrogen and few clinically significant metabolic effects so able to be used by most women even when combined hormonal contraceptives (such as the pill) are contraindicated due to medical concerns.
  • Relief of menstrual cramps.
  • Over time this method is very cost-effective.


  • Irregular bleeding that is unpredictable and may include prolonged bleeding, frequent bleeding, infrequent bleeding or no bleeding at all. While not dangerous this side effect can be inconvenient.
  • Minor side effects. While uncommon symptoms such as headache, emotional liability, loss of libido, vaginal dryness and weight gain have been reported.
  • Rare insertion complications such as local skin infection or rod expulsion.
  • Clinician-dependency. Implant must be inserted and removed by a clinician.
  • Lack of protection from sexually transmitted diseases.
  • Initial cost is higher, however many insurance plans will cover the cost of an IUD.
