Why it's doneBy Mayo Clinic staff
Mirena offers effective, long-term contraception. Among various benefits, Mirena:
- Eliminates the need to interrupt sex for contraception or seek partner compliance
- 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 three to six 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)
- Decreases the risk of endometrial cancer and possibly cervical cancer
- Can be used while breast-feeding — though there may be an increased risk of uterine perforation if inserted immediately 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
- 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
- Had previous problems with an IUD
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
