“Subdermal Etonogestrel Implants A subdermal system (Nexplanon) for delivery of etonogestrel is available for long-term reversible contraception. As shown in Table 51.1, Nexplanon is among the most effective contraceptives available. Description Nexplanon consists of a single 4-cm rod that contains 68 mg of etonogestrel, a synthetic progestin. The rod is implanted subdermally in the groove between the biceps and triceps in the nondominant arm. Etonogestrel then diffuses slowly and continuously, providing blood levels sufficient for contraception for 3 years, after which the rod is removed. If continued contraception is desired, a new rod is implanted. While currently FDA approved for 3 years, recent studies have shown that Nexplanon continues to be effective for up to 5 years post insertion. Mechanism of Action Etonogestrel suppresses ovulation and thickens cervical mucus. In addition, it causes the endometrium to become involuted and hence hostile to implantation.”
