Abstract

Background: Menopause is the stage of time in which the menstruation stops following the loss of ovarian activity. The purpose of this study was to find out the effectiveness of gabapentin on hot flashes in postmenopausal women.

Materials and Methods: A randomized controlled trial from Feb 2010 to 2011 was conducted. Sixty postmenopausal women who were referred to obstetrics and gynecology ward of two educational hospitals were recruited and divided into two groups (intervention and control). Intervention group received 300 mg gabapentin three times a day for three months, while control group received placebo. The Intensity and duration of hot flashes in women scored and recorded using visual analog scale. Independent, Paired t-test and chi-square test were used for analyzing data.

Results: Intensity of hot flashes in the beginning of research in the intervention group was significantly different with the first, second and third follow-up visit (P<0.05). Also at the end of intervention a significant difference between intervention and control groups were observed regarding the intensity, frequency and duration of hot flashes (P<0.05 and P=0.01 respectively).

Conclusion: According to the findings of this study; it appears that the use of gabapentin could decrease the intensity, duration and frequency of hot flashes in postmenopausal women. For postmenopausal women who hormone therapy is contraindicated, gabapentine could be an acceptable alternative.
