How often is the intrauterine device (IUD) replaced?

From the Guidelines

The intrauterine device (IUD) should be replaced every 3-10 years, depending on the type, with the levonorgestrel-releasing IUDs (Mirena, Skyla) lasting 5 and 3 years, respectively, and the copper-containing IUD (Copper T380-A, ParaGard) lasting 10 years, as approved by the US authorities 1. The replacement schedule for IUDs varies by type, with the following durations:

• 13.5-mg levonorgestrel IUD (Skyla): 3 years
• 52-mg levonorgestrel IUD (Mirena): 5 years
• Copper IUD (Copper T380-A, ParaGard): 10 years It is essential to keep track of the IUD's expiration date and schedule a replacement appointment before that date to maintain continuous contraceptive protection, as the effectiveness of IUDs decreases after their approved duration 1. Key points to consider when replacing an IUD include:
• The type of IUD used
• The approved duration of the IUD
• The importance of scheduling a replacement appointment before the IUD expires
• The potential for decreased effectiveness after the approved duration By following the recommended replacement schedule and consulting with a healthcare provider, individuals can ensure continuous contraceptive protection and minimize the risk of unintended pregnancy 1.

From the Research

Intrauterine Device Replacement Frequency

The frequency of intrauterine device (IUD) replacement varies depending on the type of IUD.

• The copper T 380A IUD is effective for at least 10 years 2.
• The levonorgestrel (LNg) IUD appears to be effective for at least 7 years 2.
• The levonorgestrel intrauterine system 52 mg (Mirena®) can be used for 7 years 3.
• Women who are at least 35 years old at the time of insertion of a TCu380A IUD can continue use until menopause with a negligible risk of pregnancy 3.

Factors Influencing Replacement Frequency

Several factors can influence the replacement frequency of an IUD, including:

• Patient characteristics, such as age and parity 3.
• Patient preferences 3.
• Country- and community-specific factors 3.
• The type of IUD used, with different devices having different effective lifespans 2, 3.

Extended Use of IUDs

There are advantages to extended use of IUDs beyond the manufacturer-approved time period, including:

• Prolongation of contraceptive benefits 3.
• Prolongation of non-contraceptive benefits 3.
• Good evidence to support extended use of certain devices, such as the TCu380A and the TCu220 for 12 years, and the levonorgestrel intrauterine system 52 mg (Mirena®) for 7 years 3.
