How Long Does the Birth Control Implant Last?
Wondering how long the birth control implant lasts? Learn how it works, how long it’s effective, and when to replace it.
What Is the Birth Control Implant?
The birth control implant, commonly known by the brand name Nexplanon, is a small, flexible rod about the size of a matchstick. It’s inserted just under the skin of your upper arm by a healthcare provider.
The implant releases a hormone called etonogestrel, a type of progestin, which prevents pregnancy by:
-
Stopping ovulation (no egg is released)
-
Thickening cervical mucus to block sperm
-
Thinning the uterine lining to prevent implantation
It’s one of the most effective forms of birth control, with a success rate of over 99% when properly placed.[
How Long Does the Birth Control Implant Last?
The implant is designed to provide protection against pregnancy for up to 3 years.
After this time, the implant must be removed or replaced by a healthcare provider to ensure continued contraceptive protection. Some studies suggest the implant may remain effective slightly beyond 3 years, but current guidelines recommend replacement at the 3-year mark for maximum reliability.
What Happens After 3 Years?
Once the implant reaches its expiration date:
-
Its hormone levels gradually decrease, making it less effective.
-
You should schedule a removal and replacement appointment if you want to continue using it.
-
If you don’t want to get pregnant and don’t replace it, use an alternative form of contraception right away.
Can the Implant Be Removed Early?
Yes. The implant can be removed at any time before 3 years if you decide you want to:
-
Try for pregnancy
-
Switch to another form of birth control
-
Stop using hormonal contraception due to side effects
Fertility usually returns quickly after removal—many people ovulate within a few weeks.

Mood changes
