The aim of this prospective, non-interventional post-marketing surveillance study is to obtain data on safety and efficacy of Mirena in treatment of heavy menstrual bleeding (Menorrhagia) under daily-life treatment conditions.For each patient, an initial visit and one to three follow-up visits after about 3, 6 and 12 months will be documented by the treating physician on the case report form. Observations include the patient's demographic parameters (date of birth, height, weight, race and smoking habits), previous contraceptives and menorrhagia treatment, gynaecological history, baseline menstruation, result of insertion, concomitant medications and diseases as well as menorrhagia symptoms. Overall treatment success will be evaluated at the end of treatment including number of weeks until improvement and reduction of menstrual bleeding with respect to duration and severity, and patient's satisfaction.
