Nexplanon is a soft, flexible rod that is inserted under the skin of you upper arm.  It gradually releases the hormone progestin to prevent pregnancy.  It is contains no estrogen.  It is considered a long term contraceptive method because it prevents pregnancy for up to 3 years.   It is more than 99% effective so your chance of getting pregnant when using Nexplanon is very low when it is inserted correctly.

How does it work?

Nexplanon stops the release of an egg from the ovary.  It also thickens the mucus in the cervix and changes the lining of the uterus.

  • Pain, irritation, swelling, or bruising at the insertion site
  • Scarring, including a thick scar called a keloid around the insertion site
  • Infection
  • Scar tissue may form around the implant making it difficult to remove
  • The implant may come out by itself. You may become pregnant if the implant comes out by itself. Use a backup birth control method and call your health care provider right away if the implant comes out.
  • The need for surgery in the hospital to remove the implant
  • Injury to nerves or blood vessels in your arm
  • The implant breaks making removal difficult

You should not have Nexplanon inserted if you think you might be pregnant.  Talk to your health care provider about the best time to have Nexplanon inserted.

Tell your health care provider about any medications you are taking before having Nexplanon inserted.  Some medications may make Nexplanon less effective.  It is also important to discuss any health problems you have.
