About the Nexplanon contraceptive implant

Nexplanon is a single-rod, radiopaque, subdermal contraceptive implant that contains the progestogen etonogestrel. This progestogen is also known as 3-ketodesogestrel and is the active metabolite of desogestrel, which has been used in combined oral contraceptives for many years and is known to inhibit ovulation.1

Each single, flexible rod of Nexplanon is 40 mm in length and 2 mm in diameter and is non-biodegradable. The core of the Nexplanon implant contains 68 mg of etonogestrel and 15 mg barium sulphate in a matrix of the copolymer evatane. A rate-controlling membrane ensures that consistent daily doses of etonogestrel are released from the contraceptive implant over the course of its 3 years of use.1
