What is the Implanon Implant?

Implanon is a 4 centimeter long rod with a core of a progestin called etonogestrel which is inserted under the skin of the upper arm. The progestin is released slowly and Implanon remains effective for 3 years. Implanon provides a hormone much like the progesterone a woman produces during the last 2 weeks of each monthly cycle. Impalon is effective because it stops the ovaries from releasing an egg. Many clinics recommend that you use a backup contraceptive for a week after your Implanon is inserted. There were no pregnancies at all in the women participating in the clinical trials leading to approval of Implanon. Complete information about this contraceptive is available from your clinician or from the package insert that is provided when your implant is inserted.
