Brief Summary

This study is for women in Canada who are in menopause. They have symptoms including hot flashes and night sweats (also known as vasomotor symptoms or VMS). Their own doctor has prescribed fezolinetant for hot flashes and night sweats, as part of routine health care in Canada. In this study, women will be taking tablets of fezolinetant. This study is about recording information only. The women's own doctor decides on treatment, not the study sponsor (Astellas). Women are taking fezolinetant every day for up to 52 weeks (1 year). The main aim is to learn if fezolinetant improves hot flashes and night sweats after 12 weeks. Other aims are to learn if fezolinetant improves hot flashes and night sweats throughout the study. This includes improved sleep and the women's wellbeing. Details are recorded on how satisfied the women are with fezolinetant and if they completed their treatment. This includes reasons for stopping treatment. Any safety issues are recorded. Details about other treatments taken before or with fezolinetant are also recorded.
