Does Nexplanon expire? How can you tell?
Yes. Nexplanon (the etonogestrel implant) has an expiration date printed on the package and on the implant insertion device, and it is meant to be used before that date. After the labeled expiration date, the product is not considered reliable for use.
What happens if it’s past the expiration date?
Using Nexplanon past its labeled expiration date is not recommended because medication potency can decline over time. If your implant is past its expiration date, the practical next step is to contact the clinician who placed it (or your prescribing clinic) to discuss timing for replacement and ensuring contraception coverage.
If Nexplanon “expires,” does that mean the contraceptive effect stops immediately?
Expiration dates are based on product stability testing, but they do not necessarily map to an exact day when effectiveness becomes zero. The safest approach is still to follow the labeled expiration date and replace the implant through a clinician.
How does expiration relate to how long Nexplanon works for birth control?
Expiration and duration of contraception are related but not the same concept. Even if the implant remains in place for the typical multi-year contraceptive window, the labeled expiration date still matters for whether the product should be used.
What should you do right now if you’re unsure about your Nexplanon’s date?
Check the package labeling or your paperwork from the insertion. If you cannot find the expiration date, contact your clinic to confirm what implant lot/date you have and what replacement schedule they recommend.
