Copper IUD (ParaGard)

Why it's done

ParaGard offers effective, long-term contraception. It can be used in premenopausal women of all ages, including teenagers.

Among various benefits, ParaGard:

  • Eliminates the need to interrupt sex for contraception
  • Can remain in place for up to 10 years
  • Can be removed at any time
  • Can be used while breast-feeding
  • Doesn't carry the risk of side effects, such as blood clots, related to hormonal birth control methods
  • Can be used for emergency contraception if inserted within five days after unprotected sex

ParaGard isn't appropriate for everyone. Your health care provider may discourage use of ParaGard if you:

  • Have uterine abnormalities — such as large fibroids — that interfere with the placement or retention of ParaGard
  • Have a pelvic infection, such as pelvic inflammatory disease
  • Have uterine or cervical cancer
  • Have unexplained vaginal bleeding
  • Are allergic to any component of ParaGard
  • Have a disorder that causes too much copper to accumulate in your liver, brain and other vital organs (Wilson's disease)
