Can I use an IUD for heavy periods? The Mirena™ releases a low dose of the hormone progestin. The Mirena™ was originally developed to treat heavy periods in addition to providing contraception. The Mirena™ can be a good choice for women, as it can decrease heavy periods. Heavy bleeding can be due to hormones or other gynaecological problems. Before you have an IUD inserted it is important to be sure you have none of these gynaecological problems. Your doctor will arrange a check-up and may want to arrange other tests before you have a Mirena.
