Health Education Instructions for Intrauterine Contraceptive Devices (IUD) 子宮內避孕器衛教說明

2026/3/20

Most intrauterine contraceptive device (IUD) can be placed in an outpatient clinic without anesthesia. It is recommended to insert them during the non-menstrual period (usually on the 5th day of menstruation). Please note that if there is pelvic or vaginal inflammation or infection, it should be treated and resolved before placement.

Principle

The device induces a local inflammatory response, which makes it difficult for a fertilized egg to implant.

Possible Side Effects

  • May increase the risk of pelvic infection.
  • Mild lower back pain and spotting outside of menstruation may occur within the first three months after insertion.

Postoperative Care

  • The device is typically used for 5 years and should be replaced regularly.
  • The risk of displacement in the first year is approximately 5%.
  • If a pelvic infection occurs, the device should be removed and treated with antibiotics.
