Nexplanon (etonogestrel) is a hormone implant that prevents ovulation (the release of an egg from an ovary). This medication also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
Nexplanon is radiopaque implant used as contraception to prevent pregnancy. Etonogestrel is contained in a small plastic rod that is implanted into the skin of your upper arm. The medicine is released slowly into the body.
The Nexplanon rod can remain in place and provide continuous contraception for up to 3 years.
Nexplanon implants contain a small amount of barium sulfate so that the implant can be seen by X-ray.
