83% Icon

of HMB patients are satisfied with Mirena

A total of 647 patients (LNG-IUS [n=437], CMTs [n=135]) diagnosed with HMB were recruited to this non-interventional study from the eight participating countries in Asia. Patient satisfaction was recorded at the last visit (at 12 months or premature discontinuation). At each visit (at 3, 6, and 12 months), patients completed the menorrhagia multi-attribute scale to assess health related quality of life.

95% Icon

95% of first-time users of Mirena® for contraception are satisfied, rising to 99% of those on their second Mirena® IUS

Women who had used the LNG-IUS for six months or more completed a standardised questionnaire on reasons for use, user satisfaction and other aspects. A total of 8680 questionnaires were completed by survey participants in 18 countries across Europe and the Near East. The average woman using the LNG-IUS was 38 years old, was married or lived with her partner, and had two children. Overall, 95% of patients were satisfied with the LNG-IUS; the percentage rose to 99% among those using their second LNG-IUS. Reasons mentioned for using the LNG-IUS included the need for contraception (68%), its high efficacy (59%) and the shorter/lighter menstrual bleeding (55%). Of the women with prior bleeding problems, 93% reported an improvement in their symptoms with the LNG-IUS. Participants also rated the reliability, tolerability and convenience of the method highly.
