MirenaÂ® (levonorgestrel-releasing intrauterine system) is a hormone-releasing IUD that prevents pregnancy for up to 5 years. Mirena also treats heavy periods in women who choose intrauterine contraception. Mirena is recommended for women who have had a child.
Not only is it more than 99 percent effective as a form of birth control, but most women who use Mirena eventually have much lighter menstrual flow â and some users stop having periods completely. The progestin IUD can stay in place for up to five years.
