NEXPLANON – Contraceptive Implant Study (Click here to learn more)

The Nexplanon® implant is approved for use to prevent pregnancies for up to 3 years. It has not been approved to use for more than 3 years. The purpose of this clinical trial is to confirm that the use of the implant for more than 3 years:

  • remains effective to prevent pregnancy
  • remains safe
  • maintains menstrual cycle (periods) control

  • Are between 18 and 35 years old

Being part of this clinical trial is voluntary.

You may choose to join the study or not. If you choose to be part of the trial, you can change your mind and discontinue at any time. This will not affect care you receive outside of the trial or any medical benefits that you had before the trial.
