In simple words: A levonorgestrel-releasing implant is a long-term birth control method. It's a small, flexible rod placed under the skin of your upper arm that releases the hormone levonorgestrel to prevent pregnancy.

The levonorgestrel-releasing contraceptive implant system releases the hormone levonorgestrel, a progestin hormone that changes the uterine lining and prevents sperm from reaching the uterus or prevents a fertilized egg from attaching to the uterus to prevent pregnancy. The typical implant system consists of small plastic rods that a provider inserts under the skin of a patient’s upper arm, which then gradually release the hormone into the patient’s body over time.

Example 1: A 25-year-old woman requests a long-acting reversible contraceptive method. After discussing her options, she chooses the levonorgestrel implant. The provider inserts the implant subdermally in her upper arm., A 32-year-old woman with a history of difficult-to-control epilepsy needs reliable contraception that won't interact with her anti-epileptic medications. The levonorgestrel implant is a suitable option, and the provider performs the insertion., A teenager seeks contraception. After counseling about various methods, including short-term and long-term options, the patient selects and receives the levonorgestrel implant.

Documentation should include informed consent from the patient, the date of insertion, the location of insertion (upper arm), the lot number of the implant, and any complications during or after the procedure.
