Etonogestrel implants are used to prevent pregnancy. These implants are put directly into the uterus to prevent pregnancy. While the implant is in, it provides a constant flow of estrogen to the body to stop it from releasing eggs or allowing fertilized eggs to implant themselves in the uterus.
This medication does not protect against sexually transmitted diseases. Women who are worried about HIV or other STDs can’t rely on implants to stop them from getting these diseases.
Some patients are allergic to implants. They may have difficulty breathing, swelling of the face and tongue, or hives and rashes. Contact your doctor immediately if you have any of these symptoms.
