Nexplanon (Merck), a modified version of the contraceptive implant Implanon (Merck), is now available in the US. Nexplanon contains 68 mg of the progestin etonogestrel and is bioequivalent to Implanon. Both products are single-rod subdermal contraceptives implanted into the inside of the upper arm; both provide reversible effective contraception for up to 3 years.1 Nexplanon has a redesigned preloaded applicator intended to make insertion easier and reduce the risk of improperly placed devices. Proper placement is necessary to ensure adequate contraceptive efficacy and to facilitate future removal of the implant. Unlike Implanon, Nexplanon is radiopaque (contains barium sulfate) and can be located using an X-ray or CT scan when the device is not palpable. Providers should receive training before inserting or removing Nexplanon. Nexplanon will replace Implanon once all registered providers have completed the training program. The wholesale acquisition cost of a single Nexplanon implant is $659.42.2
