An Overview of the ParaGard Copper IUD

Copper T 380A IUD

The ParaGard Intrauterine Device (IUD) Copper T 380A is a small, "T-shaped" contraceptive device, about 1-1/4 inches wide by 1-3/8 inches long, made of flexible plastic and wrapped in copper.

The ParaGard IUD must be inserted by a qualified healthcare provider (such as an OB/GYN or nurse practitioner). It is hormone-free, so it does not alter a woman’s natural menstrual cycle.

The ParaGard IUD releases a tiny amount of copper (which acts as a spermicide) continuously over a 10-year period as a way to prevent pregnancy.

How It Works

The ParaGard IUD helps to prevent sperm from joining with an egg by interfering with the movement of the sperm toward the egg. It is also believed that the ParaGard IUD causes changes in the lining of the uterus to reduce the likelihood of implantation.

ParaGuard protects against pregnancy immediately after insertion.

Copper Found in ParaGard

Copper is an essential trace mineral that is naturally present in a person’s body and found in foods like whole grains, shellfish, leafy greens, and nuts.

The small amount of copper that the ParaGard IUD releases each day is less than the amount contained in the average daily diet. The copper in the ParaGard IUD does not increase the overall level of copper already present in one’s body.

Who Should Use It

The FDA has approved hormone-free ParaGard for women throughout their entire reproductive lives—from age 16 until menopause.

The American College of Obstetricians and Gynecologists reports the ParaGard IUD is safe and effective for young women, however, not all healthcare providers are familiar with the updated guidelines and may be reluctant to insert an IUD in teenaged girls.


  • Can be used while breastfeeding.
  • Does not alter or affect a woman's hormone levels.
  • IUDs can improve a woman's sex life by allowing for spontaneity.
  • It can provide continuous pregnancy prevention for 10 years and can be removed anytime within that 10 year period.
  • A good alternative option for women who cannot tolerate or do not wish to use hormonal birth control methods or hormone IUDs (Mirena or Skyla).
  • After removing the IUD, a woman’s ability to become pregnant returns quickly.
  • Eco-friendly method of contraception.
  • It is an extremely private and discreet birth control method. Nobody can tell if you are using it, and there is no packaging or other evidence of use that may embarrass some woman.
  • Convenient and hassle-free—once inserted, you don’t have to do anything.
  • An Extra Advantage: The ParaGard IUD can be used as a form of emergency contraception. If it is inserted within 5 days after unprotected intercourse, ParaGard can reduce the risk of pregnancy by 99.9%.


Although most women do not experience any trouble adjusting to having an IUD, some women may have heavy bleeding and cramping during the first few weeks or months after insertion. However, healthcare providers can prescribe medication that can lessen cramps and bleeding during menstruation.

Some women experience cramping or a backache for several days or weeks after an IUD is inserted. Spotting may occur between periods during the first few months of IUD use.

A woman’s first few periods after an IUD insertion may last longer, and the flow may be heavier. It is not unusual for a woman to have heavier and longer periods while using the ParaGard IUD.

Side Effects

Women may experience side effects, but in most cases, they will go away after the first few weeks to months. This includes:

  • Lower abdominal pain, cramps, and/or back pain.
  • Spotting between first few periods.
  • The ParaGard IUD may cause a 50% to 75% increase in menstrual flow, which for some women, may increase their risk for anemia.

Serious problems, such as perforation of the uterus or infection, are rare with the ParaGard IUD. It is critical to report any problems to your healthcare provider right away to avoid further complications.

IUD Removal

  • After 10 years are up, you must have the ParaGard IUD removed. You can choose to have another one inserted during the same visit.
  • You can also have the IUD removed at any time before the 10 year period ends.

ParaGard must be removed by a healthcare provider. You should not try to take it out yourself. 

  • If ParaGard is expelled, you may not even notice. This is why it is so important that you check for the IUD strings so you know that your ParaGard is still there. If it has moved, you need to contact your healthcare provider to have another one inserted. Your practitioner will most likely perform a pregnancy test, to make sure that you are not pregnant, before inserting a new ParaGard IUD.
  • If the ParaGard IUD has become partially expelled, it is important to call your healthcare provider right away and use backup birth control.

Associated Costs

If you plan to use birth control for at least 1 to 2 years, an IUD is the least expensive contraceptive option available. The one-time cost of ParaGard, in comparison to other contraceptive methods, could save you hundreds of dollars or more over time.

Medicaid may cover these costs. In general, the charges from family planning clinics will usually be less than private healthcare providers.

ParaGard should be covered with no out-of-pocket costs for most insurance plans, but check your policy in advance to confirm coverage.


ParaGard is one of the most effective reversible methods of birth control available. The ParaGard IUD is 99.2-99.4% effective. This means that out of every 100 women who use ParaGard in one year, less than one will become pregnant with typical use as well as with perfect use.

The majority of pregnancies that happen to ParaGard users occur because the ParaGard has slid out without them realizing it.

Though the chance of pregnancy while using ParaGard is very low, if it does happen, you should contact your healthcare provider once you know you are pregnant.

STD Protection

ParaGard offers no protection against sexually transmitted diseases.
