Mirena Risks

Women who experience bothersome side effects with oral birth control pills may find Mirena® a better choice. This device is inserted into a woman's uterus, where it can remain in place for up to five years. It prevents pregnancy by stopping ovulation and by causing certain changes in the cervix and uterus. The device is usually safe and effective, although there are some risks with Mirena to be aware of.
For example, this product can cause inflammatory pelvic disease (IPD) and can put a woman at risk for an ectopic pregnancy. In addition, although rare, some women experience severe pain within a few hours of Mirena being inserted, which is a sign of a serious infection.
Mirena also carries a risk of side effects, although these are usually mild and easily treated. Commonly reported reactions in clinical studies included menstrual changes, abdominal pains, and nausea.
