Antidepressant useful for hot flashes
The antidepressant venlafaxine (Effexor) appears to be effective in treating postmenopausal hot flashes in otherwise healthy women, according to a report in the journal Obstetrics & Gynecology.
Previous studies have confirmed the value of venlafaxine in treating hot flashes in women with breast cancer and those reluctant to use estrogen because of breast cancer fears, the authors explain.
In this study, Dr. Robert B. Jaffe and colleagues from University of California, San Francisco, investigated whether extended-release venlafaxine would reduce hot flashes in a general population of postmenopausal women. Eighty women were randomly treated with either venlafaxine or inactive “placebo.”
Women in the venlafaxine group reported higher hot flash scores when the study began, the researchers note, but their scores declined to the level of the control group at one-month follow-up.
By the time the 12-week study was completed, the authors report, women in the venlafaxine group had substantially lower hot flash scores than did women in the placebo group.

When they occurred, the hot flashes were not, on average, significantly less severe in the venlafaxine group, the results indicate.
venlafaxine treatment was associated with significant improvement in mental health and vitality compared with placebo, the investigators report, but there was evidence that venlafaxine adversely affected sexual function in some women.
“Although several adverse effects were noted in the venlafaxine group,” the researchers write, “most women...continued treatment beyond the conclusion of the study, suggesting that the benefits of treatment outweighed the discomfort of the adverse effects.”
“This study indicates that extended-release venlafaxine is an effective treatment option for postmenopausal” hot flashes, the authors conclude.
