The contraceptive implant, commonly known by its brand name Implanon, is a small, flexible plastic rod about the size of a matchstick that is inserted subdermally into the upper arm to provide long-term birth control. The procedure to insert the implant is straightforward and typically performed in a healthcare provider's office. First, the area on the inner side of the upper arm is cleaned and numbed with a local anesthetic to minimize discomfort. Once the area is numb, the healthcare provider uses a specialized applicator to insert the implant just under the skin, ensuring proper placement. The entire insertion process usually takes only a few minutes.

After the insertion, the healthcare provider will palpate the site to confirm that the implant is correctly positioned. A small adhesive bandage is applied to the insertion site, and sometimes a pressure bandage is also used to minimize bruising and swelling. Patients are often advised to keep the area dry and avoid heavy lifting with the affected arm for a short period to ensure proper healing. The implant can remain effective for up to three years, steadily releasing a low dose of the hormone etonogestrel to prevent ovulation. It is important for patients to have periodic check-ups to ensure the implant is functioning correctly and to discuss any side effects. Removal of the implant, when desired, is also a minor procedure conducted by a healthcare professional.
