Additional Uses of IUDs


  • IUD as Emergency Contraception: A Copper IUD can be inserted up to five days after unprotected intercourse to prevent pregnancy. The Copper IUD is considered the most effective method of emergency contraception when other methods of contraception fail or were not used.[i]


  • Therapeutic Uses of IUDs:  IUDs also offer important non-contraceptive health benefits. Copper IUDs are protective against the development of endometrial cancer. Levonorgestrel-containing IUDs (Mirena) are effective in treating a variety of gynecological disorders, including heavy menstrual bleeding and anemia, and have also been used effectively to reduce side effects associated with hormonal replacement therapy.[ii]
