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

Among various benefits, Mirena:

  • Eliminates the need to interrupt sex for contraception
  • Doesn't require partner participation
  • Can remain in place for up to five years
  • Can be removed at any time, followed by a quick return to baseline fertility
  • Decreases menstrual bleeding after at least several months of use
  • Decreases severe menstrual pain and pain related to endometriosis
  • Decreases the risk of pelvic inflammatory disease caused by sexually transmitted infections (STIs) by causing the cervical mucus to thicken, creating a barrier against bacteria
  • Decreases the risk of endometrial cancer and possibly cervical cancer
  • Can be used while breast-feeding — though the recommendation is to wait at least six weeks after childbirth
  • Doesn't carry the risk of side effects related to birth control methods containing estrogen

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

  • Had or have breast cancer
  • Have uterine or cervical cancer
  • Have liver disease
  • Have uterine abnormalities, such as fibroids, that interfere with the placement or retention of Mirena
  • Currently have a pelvic infection or have a history of pelvic inflammatory disease
  • Have unexplained vaginal bleeding
  • Have inflammation of the vagina or cervix or a lower genital tract infection
  • Are allergic to any component of Mirena
  • Have or are at high risk of a sexually transmitted infection

In addition, tell your health care provider if you:

  • Take any medications, including nonprescription and herbal products
  • Have diabetes or high blood pressure
  • Have a heart condition or have had a heart attack
  • Have migraines
  • Have blood-clotting problems or have had a stroke
  • Recently gave birth or are breast-feeding
