Levonorgestrel iud


Generic Name: levonorgestrel (LEE-voe-nor-JES-trel)
Brand Name: Mirena

Levonorgestrel iud is used for:

Preventing pregnancy for up to 5 years in certain women. It is also used to treat heavy menstrual bleeding.

Levonorgestrel iud is a progestin intrauterine device (IUD). It may work in several ways. It may change cervical mucus to prevent the sperm from reaching the egg. It may also change the lining of the uterus to prevent implantation in the uterus if an egg is fertilized. This change in the lining of the uterus also helps to decrease heavy menstrual bleeding.

  • you are allergic to any ingredient in this product, including silicone or polyethylene
  • you are pregnant or suspect that you are pregnant
  • you have an abnormally shaped uterus or uterine fibroid tumors that change the shape of your uterus
  • you currently have pelvic inflammatory disease (PID) or you have a history of PID and have not had a normal pregnancy since that time
  • you have a history of ectopic pregnancy, endometritis, or a condition that puts you at risk of ectopic pregnancy or pelvic infections
  • you have had an inflamed lining of the uterus after pregnancy or an infected abortion within the past 3 months
  • you have an abnormal Pap smear of unknown cause; vaginal bleeding of unknown cause; inflammation of the cervix or vagina; an infection of the genitals, vagina, or cervix that has not been treated; or any sexually transmitted disease (STD) (eg, chlamydia, gonorrhea)
  • you have a condition that makes it easier for you to get an infection (eg, leukemia, immune system problems, HIV infection)
  • you have risk factors that increase your chance of getting an infection (eg, you or your sex partner have more than one sex partner, intravenous [IV] substance abuse)
  • you have a previously inserted IUD that has not been removed
  • you have a history of breast cancer or you know or suspect that you have breast cancer
  • you know or suspect that you have cancer of the uterus or cervix

Contact your doctor or health care provider right away if any of these apply to you.
