Hormonal therapy affected by antidepressants?

Page last modified on: July 31, 2008

Question from Hjshaman: How is hormonal therapy affected, if at all, by the use of antidepressants?

Answer —Marisa Weiss, M.D., president and founder: For women who are experiencing depression or hot flashes while on tamoxifen, studies have found that low doses of antidepressants like Paxil (chemical name: paroxetine) or Effexor (chemical name: venlafaxine) can reduce hot flashes by about one half to two thirds.

Recently, there was some concern expressed about whether the antidepressants may interfere with the effectiveness of hormonal therapy. This concern has not been substantiated. At this time, most oncologists—as well as primary care doctors—still feel comfortable giving low doses of these medications to improve the quality of life relative to hot flashes (low doses of these meds) or for depression (higher doses of these meds).

On Wednesday, April 21, 2004, our Ask-the-Expert Online Conference was called Hormonal Therapy Updates. Sandra Schnall, M.D. and Marisa Weiss, M.D. answered your questions about hormonal therapies and answered questions about which ones work best in different situations, how they might fit into your treatment sequence, how to deal with side effects, and more.
