The Nexplanon, or the “implant,” is a 4 cm long flexible plastic rod that is inserted just underneath the skin of the upper arm. The Nexplanon in the absolute most effective birth control method and lasts for five years. Less than 1 out of 100 people will become pregnant using this method in a year.

What should I know about it? 

It slowly releases small amounts of progestin, a hormone that prevents pregnancy by stopping ovulation (release of an egg) from the ovaries and blocking sperm from entering the uterus. The Nexplanon lasts for five years. Your bleeding may stop all together, become lighter and less frequent, or become irregular. Side effects can include headache, breast tenderness, and mood changes among others. Nexplanon is placed superficially in the skin and is easily felt in the arm, but it is extremely unlikely to move or be damaged.

What is it like to have a Nexplanon inserted?

Nexplanon insertion appointments usually last 40 minutes, and it is important to arrive 15 minutes before your appointment time for check-in. A pregnancy test is done to rule out pregnancy the day of insertion, so it is important not to have unprotected sex at least two weeks prior to your appointment. At the visit, the provider will inject a small amount of numbing medicine under the skin of your upper arm so that you won’t experience any pain with the insertion of the Nexplanon. The insertion itself only takes a few seconds. Steri-Strips will be placed over the insertion site, and your arm wrapped with a gauze bandage that stays on for 24 hours. We will give you special post-insertion instructions the day of your visit.
