The ParaGard T-380A is an IUD with copper, manufactured and marketed in the United States by Duramed Pharmaceuticals. It is the only copper-containing intrauterine device approved for use in the U.S. (a hormonal uterine device, the Mirena, is also approved). The ParaGard consists of a T-shaped polyethylene frame wound with copper wire, along with two monofilament threads to aid in removal of the IUD. The ParaGard is typically inserted and removed under local anesthesia in a gynecologist's office. The ParaGard is currently approved for 10 years use, however the newest data show it actually remains effective for at least 12 years, and perhaps beyond, after which it should be removed and replaced if desired. The ParaGard can be used as a form of emergency contraception if inserted within three to five days after unprotected intercourse, and it can be inserted directly after childbirth.
