Mirena (IUD) Birth Control Information

Women who have had at least one child already and desire birth control may use Mirena®. This is an intrauterine device (IUD), or, more accurately, an intrauterine system (IUS), since it contains a progesterone hormone. A healthcare provider inserts the IUD into a woman's uterus, where it can remain for up to five years. For most women, the medication works by stopping ovulation; in other women, it triggers certain changes in the cervix and uterus that make it harder for conception to occur.
In general, this product is a safe, effective form of birth control; however, Mirena is not suitable for everyone. For example, women who have inflammatory pelvic disease, cervical cancer, or who have multiple sexual partners may need to consider a different form of contraception.
In addition, side effects are possible -- common ones include headaches, menstrual changes, and stomach cramps. Fortunately, most women tolerate this form of birth control well, and if any side effects do occur, they are usually mild and easily treated.
