The ParaGard® T 380A intrauterine copper contraceptive is a T-shaped device (IUD), measuring
32 mm horizontally and 36 mm vertically with a 3 mm diameter bulb at the tip of the vertical stem.
A monofilament polyethylene thread is tied through the tip, resulting in two white threads, each at least 10.5 cm in length, to aid in detection and removal of the device. The T-frame is made of polyethylene, with barium sulfate to aid in detecting the device under x-ray. ParaGard® contains approximately 176 mg of copper wire coiled along the vertical stem and a 68.7-mg copper collar
on each side of the horizontal arm. The total exposed copper surface area is 380 ± 23 mm2.
No component of ParaGard® or its packaging contains latex.
ParaGard® is packaged with an insertion tube and a solid white rod in a pouch that is then sterilized. A movable flange on the insertion tube aids in gauging the depth of insertion through the cervical canal and into the uterine cavity.![]()
ParaGard® is believed to work primarily by preventing sperm from reaching and fertilizing the egg.1
It may also prevent the egg from attaching to the uterus. The contraceptive effectiveness of ParaGard® is enhanced by the continuous release of copper into the uterine cavity. ParaGard® is indicated for intrauterine contraception for 1, 5, even up to 10 years, but patients may have it removed anytime before then, depending on their needs and family circumstances. ![]()
ParaGard® was approved by the FDA in 1984 and has been sold and used in the
United States since 1988.2 ![]()

ParaGard® does not protect against HIV/AIDS or other sexually transmitted infections. ParaGard® must not be used by women who are or may be pregnant; have acute pelvic inflammatory disease (PID) or current behavior suggesting a high risk for PID; have had a postpregnancy or postabortion uterine infection in the past 3 months; have cancer of the uterus or cervix; have an infection in the cervix; have an allergy to any component; or have Wilson's disease. The most common side effects of ParaGard® are heavier and longer periods and spotting between periods; for most women, these typically subside after 2 to 3 months. If a woman misses her period, she must be promptly evaluated for pregnancy. Some possible serious complications that have been associated with intrauterine contraceptives, including ParaGard®, are PID, perforation of the uterus, and expulsion.
