Brief Summary:

The primary objective in this study is collecting post-marketing information on the safety. Thus, it includes information under the routine clinical practice on adverse events (AEs) and adverse drug reactions (ADRs) including expulsion and abnormal bleeding that occur within the first 12 months Mirena insertion.

The secondary objective(s) in this study is/are collecting information on Mirena effectiveness, such as periodic blood loss and Quality of life (QOL), use of analgesic and dysmenorrhea pain as far as these are recorded under routine clinical practice.

Condition or disease Intervention/treatment
Menorrhagia, Dysmenorrhea Drug: Mirena (Levonorgestrel IUS, BAY86-5028)

Detailed Description:

This local, non-interventional, multicenter, single-cohort study using primary data includes patients treated with Mirena for Heavy menstrual bleeding(HMB) and/or dysmenorrhea (contraception is not included).

A total of 600 patients (valid for safety analysis) is planned to be enrolled in two years. No formal sample size estimation was conducted, it was determined based on feasibility.

Target population is patients with HMB and/or dysmenorrhea diagnosis. The treatment should be performed based on the product label in Japan. The standard observation period will last for 12 months from starting Mirena treatment.
