Non-hormonal-based treatments for menopausal symptoms
Summary practice points
As clinicians we must be familiar with alternative therapies, to help inform and guide women as to which options are most likely to be beneficial to them.
Few complementary and alternative treatment options have proven evidence of effectiveness, but although many options do not stand up to scrutiny from a robust and evidence based perspective there will be individual women who will benefit from some of these treatments
Placebo effect is not inconsiderable and in menopausal studies will play a part in individual experience and reported benefits.

The evidence is strong that exercise, yoga, paced respiration, and acupuncture do not work for hot flushes, although they may offer other health benefits, so the panel advises providers not to recommend them as hot flush therapy
Studies on over-the-counter and herbal therapies (such as black cohosh, dong quai, evening primrose, flaxseed, maca, omega-3s, pollen extract, and vitamins), relaxation, calibration of neural oscillations (a brain-training technique), and chiropractic intervention show that these therapies are unlikely to help, so the panel advises providers not to recommend them at this time. The panel also advises providers not to recommend stay-cool techniques and avoiding hot flush “triggers” at this time. These approaches are risk-free but don’t have studies testing their effectiveness, and sticking with these can just delay appropriate and effective treatment.
