Name: Nexplanon implant
What is Nexplanon (etonogestrel implant)?
Etonogestrel is a hormone 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.
Etonogestrel implant is used as contraception to prevent pregnancy. The medicine 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 rod can remain in place and provide continuous contraception for up to 3 years.
Etonogestrel implant may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before receiving the Nexplanon (etonogestrel implant)?
Using an etonogestrel implant can increase your risk of blood clots, stroke, or heart attack. You are even more at risk if you have high blood pressure, diabetes, high cholesterol, or if you are overweight. Your risk of stroke or blood clot is highest during your first year of using this medicine.
Smoking can greatly increase your risk of blood clots, stroke, or heart attack. Your risk increases the older you are and the more you smoke. You should not use this medicine if you smoke and are over 35 years old.
Do not use if you are pregnant. If you have recently had a baby, wait at least 3 weeks (4 weeks if breast-feeding) before receiving an etonogestrel implant.
You may need to have a negative pregnancy test before receiving the implant.
You should not use this implant if you are allergic to etonogestrel, or if you have:
a history of heart attack, stroke, or blood clot;
a history of hormone-related cancer such as breast or uterine cancer;
unusual vaginal bleeding that has not been checked by a doctor; or
liver disease or liver cancer.
To make sure etonogestrel implant is safe for you, tell your doctor if you have:
high cholesterol or triglycerides, or if you are overweight;
high blood pressure;
a history of depression; or
if you are allergic to numbing medicines.
The etonogestrel implant should not be used in girls younger than 18 years old.
Do not use the implant if you are breast-feeding a baby younger than 4 weeks old.
What happens if I overdose?
If the implant is correctly inserted, an overdose of etonogestrel is highly unlikely.
What should I avoid while taking Nexplanon (etonogestrel implant)?
Do not smoke while using etonogestrel implant, especially if you are older than 35 years of age.
Etonogestrel implant will not protect you from sexually transmitted diseases--including HIV and AIDS. Using a condom is the only way to protect yourself from these diseases.
