IUD & Implant Expiration Calculator (When to Replace)

How it works

replace-by date = insertion date + approved duration · levonorgestrel IUD 52 mg: 8 years · 19.5 mg: 5 years · 13.5 mg: 3 years · copper T380A: 10 years · etonogestrel implant: 3 years · levonorgestrel 2-rod implant: 5 years

Long-acting reversible contraceptives work for years, but each has an approved duration after which protection is no longer guaranteed. The 52 mg hormonal IUDs (Mirena, Liletta) are now FDA-approved for 8 years, Kyleena for 5 and Skyla/Jaydess for 3; the copper T380A IUD for 10 years (with evidence to 12); and the etonogestrel implant for 3 years, with studies suggesting it lasts longer. UK guidance lets a copper IUD inserted at 40+ stay until menopause, and a 52 mg hormonal IUD inserted at 45+ stay until 55. A new device can usually be placed at the same visit the old one is removed.

Worked example

A 52 mg levonorgestrel IUD (Mirena or Liletta) inserted on March 10, 2022 at age 30 is approved for 8 years, so it should be replaced by Sunday, March 10, 2030. A copper IUD inserted the same day would last until March 10, 2032.
