Hot Flash Relief From Antidepressants

Medications could be an alternative for hormone replacement therapy during menopause

A widely available antidepressant medication appears be an effective alternative for hormone replacement therapy for those menopausal women whose lives are disrupted by frequent hot flashes, a new clinical trial shows.

This study builds on others that find antidepressants can be effective in treating hot flashes.

The drug, desvenlafaxine, controlled moderate to severe hot flashes in 62 percent of the women who took it for 12 weeks, as opposed to just 38 percent of women taking a placebo, says researcher JoAnn Pinkerton, M.D., a professor of obstetrics and gynecology and director of the Midlife Health Center at the University of Virginia.

The antidepressant was introduced in 2008 under the brand-name Pristiq, and the petition to label the drug for use in reducing hot flashes is pending before the Food and Drug Administration, she says.

"To me as a clinician this is really exciting, because I need to have some options for women who can't take estrogen or who choose not to take it," Pinkerton says. "To have something that's FDA-approved will be incredibly helpful."

The findings were presented earlier this month at the annual clinical meeting of the American Congress of Obstetricians and Gynecologists.

Pinkerton and her colleagues evaluated 365 women in a multi-center study supported by drug manufacturer Pfizer. The women, whose average age was 54, had to have experienced at least seven hot flashes a day or 50 per week in order to participate.

After 12 weeks, the women taking Pristiq saw their symptoms reduced by 62 percent, while those on placebos saw a 38 percent reduction in symptoms, Pinkerton reported. She says the researchers chose to study the women with the most intense symptoms, because if the medication could help them, it would most likely help others.
