How long is nexplanon good for?

Nexplanon is a small, flexible rod that’s inserted just under the skin of your upper arm. The implant releases a steady dose of the hormone progestin to prevent pregnancy, and it’s designed to work for about three years (36 months).

• After 3 years: the implant can be removed, and if you still want contraception, you can have a new Nexplanon inserted right away.
• Earlier removal: If you’re unhappy with side‑effects, want a pregnancy, or need to switch to a different method, it can be taken out at any time.
• Replacement: Some people choose to have a fresh implant inserted immediately after removal, so the new one starts working right away.

So, in short: Nexplanon stays in place for roughly three years, after which you can choose to keep going with a new implant or switch to another birth‑control method.
