Nexaplanon is an implant which is inserted under the skin in your upper arm. It consists of a flexible, single rod about the size of a matchstick. It releases progesterone into the body and helps prevent pregnancy for up to three years.

The progesterone which is released from the implant prevents pregnancy by stopping ovulation, thickening the cervical mucous, and by thinning the uterine lining.

The implant is inserted into your arm by your healthcare provider. First the skin is numbed with a local anesthetic. The implant is then placed under the skin with a special inserter. This takes only a few minutes.

Implant removal is brief as well. Once again, the area is numbed. A small incision is made over the area then the implant is removed.

Benefits of the implant:

  • Once it is in place, you do not have to do anything to prevent pregnancy.
  • No one can tell that you are using birth control.
  • It can be inserted immediately after an abortion, miscarriage, or childbirth and while breastfeeding.
  • It does not interfere with sex or daily activities.
  • Almost all women are able to use the implant.

If you wish to become pregnant or wish to stop using it, you can simply have the implant removed.


  • Difficulty with insertion or removal of the implant. This occurs in less than 2% of women.
  • Although rare, if pregnancy occurs while implant is in place, there is a higher risk that the pregnancy may occur in the tubes(Ectopic pregnancy).
