PATIENT CHECKLIST (updated)
If pregnancy should occur with Mirena in place, Mirena should be removed. Removal or manipulation of Mirena may result in pregnancy loss...
Long-term effects and congenital anomalies
...Some observational data support a small increased risk of masculinization of the external genitalia of the female fetus following exposure to progestins at doses greater than those currently used for oral contraception. Whether these data apply to Mirena is unknown.
...Embedment may decrease contraceptive effectiveness and result in pregnancy (see WARNINGS, Ectopic Pregnancy and Intrauterine Pregnancy). An embedded Mirena should be removed. Embedment can result in difficult removal and, in some cases surgical removal may be necessary.
...If perforation occurs, pregnancy may result (see WARNINGS, Ectopic Pregnancy and Intrauterine Pregnancy). Mirena must be located and removed; surgery may be required. Delayed detection of perforation may result in migration outside the uterine cavity, adhesions...
The risk of perforation may be increased in lactating women, in women with fixed retroverted uteri, and during the postpartum period. To decrease the risk of perforation postpartum, Mirena insertion should be delayed a minimum of 6 weeks after delivery or until uterine involution is complete. If involution is substantially delayed, consider waiting until 12 weeks postpartum...
Partial or complete expulsion of Mirena may occur (see PRECAUTIONS, Continuation and Removal). Symptoms of the partial or complete expulsion of any lUD may include bleeding or pain. However, the system can be expelled from the uterine cavity without the woman noticing it. Partial expulsion may decrease the effectiveness of Mirena. As menstrual flow typically decreases after the first 3 to 6 months of Mirena use, an increase of menstrual flow may be indicative of an expulsion. If expulsion has occurred, Mirena may be replaced within 7 days of a menstrual period after pregnancy has been ruled out.
...Most of these follicles are asymptomatic, although some may be accompanied by pelvic pain or dyspareunia. In most cases the enlarged follicles disappear spontaneously during two to three months observation. Persistent enlarged follicles should be evaluated...
