How Long Can You Keep Nexplanon In

How Long Nexplanon Is Approved to Stay In

Nexplanon is a single-rod implant placed in the upper arm that releases etonogestrel to prevent pregnancy. The FDA-approved duration is up to 5 years, and it should be removed by that point. Studies show the implant remains effective throughout this window, but it is not designed to work indefinitely.

What Happens If You Keep Nexplanon Past 5 Years

Keeping Nexplanon beyond the approved 5-year mark is not recommended. While some research suggests the hormone levels may remain sufficient for a short period after the 5-year mark, the manufacturer does not support extended use. The primary risk is a gradual decline in contraceptive effectiveness, which increases the chance of unintended pregnancy. There is also limited data on long-term hormone exposure beyond the studied timeframe.

Signs It Is Time to Remove or Replace

Several changes can signal that the implant is reaching the end of its effective window:

• Irregular bleeding patterns that differ from your usual experience
• Insertion-site pain or discomfort that does not resolve
• A feeling that the rod is more palpable or visible than before
• Unplanned pregnancy, which indicates the implant may no longer be effective

Timing for Removal and Replacement

Removal should ideally occur on or before the 5-year anniversary. A new implant can be inserted immediately after removal, and protection is considered continuous if the new rod is placed within the recommended window. If you are unsure whether your implant is still within its effective period, check your insertion card or contact the clinician who placed it. They can confirm the date and help schedule removal or replacement without gaps in coverage.
