How is the etonogestrel implant used?
The timing of when you will receive this implant depends on whether you were using birth control before, and what type it was.
Etonogestrel implant is inserted through a needle (under local anesthesia) into the skin of your upper arm, just inside and above the elbow. After the implant is inserted, your arm will be covered with 2 bandages. Remove the top bandage after 24 hours, but leave the smaller bandage on for 3 to 5 days. Keep the area clean and dry.
You should be able to feel the implant under your skin. Tell your doctor if you cannot feel the implant at any time while it is in place.
Etonogestrel implant can remain in place for up to 3 years. If the implant is placed correctly, you will not need to use back-up birth control. Follow your doctor's instructions.
You may have irregular and unpredictable periods while using the etonogestrel implant. Tell your doctor if your periods are very heavy or long-lasting, or if you miss a period (you may be pregnant).
If you need major surgery or will be on long-term bed rest, or if you need medical tests your etonogestrel implant may need to be removed for a short time. Any doctor or surgeon who treats you should know that you have an etonogestrel implant.
Have regular physical exams and mammograms, and self-examine your breasts for lumps on a monthly basis while using this medicine.
The etonogestrel implant must be removed by the end of the third year after it was inserted and may be replaced at that time with a new implant. After the implant is removed, your ability to get pregnant will return quickly. If the implant is not replaced with a new one, start using another form of birth control right away if you wish to prevent pregnancy.
Call your doctor at once if it feels like the implant may be bent or broken while it is in your arm.
