Why it's doneBy Mayo Clinic Staff
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:
