  1. Non-hormonal therapy Marco Gambacciani and Paula Albertazzi

  2. Is there a proven place for phytoestrogens in the menopause? Phytoestrogens are estrogens derived from plants We need : Differentiation of different agents Standardization of dosages Safety and efficacy labelling Currently, there is no reliable evidence confirming a substantial role for phytoestrogens in the treatment of postmenopausal women Their increasing promotion should not be endorsed by the medical profession by accepting promotional materials in journals or at meetings Ginsburg J, Prelevic G. Climacteric 1999;2:75-8

  3. EditorialsPhytoestrogen therapy for menopausal symptoms? There's no good evidence that it's any better than placebo Women experiencing mild menopausal symptoms may gain relief by dietary modification and lifestyle changes, such as reducingsmoking and consumption of caffeine and alcohol, stress management,and increased exercise However, there is no evidence to supportthe belief that even a very high intake of soy products will alleviatehot flushes, night sweats, and other symptoms such as vaginaldryness, mood changes, and musculoskeletal symptoms No absoluteconclusions can be drawn from the few studies of the effects ofphytoestrogens on bone. As with other interventions of unprovedefficacy, long-term randomized trials will be required to determinethe place (if any) of phytoestrogens in the management of postmenopausalwomen Davis SR. BMJ 2001;323:354-5

  4. Not all placebos are equally pleasing Given the 57% reduction in hot flushes seen in the placebo groups of randomized, controlled trials of oral HRT, there is understandable scepticism about claims for the efficacy of products, usually complementary medicine, which find a reduction in vasomotor symptoms equal to or less than the normal 57% placebo effect A statistically significant effect may be claimed in such studies because the placebo effect was unusually small Sturdee DW, MacLennan AH. Climacteric 2006;9:401–3

  5. Non-hormonal therapies for menopausal hot flushes Few high-quality trials have been published; most of them have methodological deficiencies. Hence, generalizability is limited Red clover isoflavone extracts had no effects and results were mixed for soy isoflavone extracts The effects are less than for estrogen The SSRIs or SNRIs, clonidine, and gabapentin trials provide some evidence for efficacy These therapies may be useful for highly symptomatic women who cannot take estrogen Possible adverse effects and the high cost in different countriesmay restrict use for many women

  6. Alternative treatments The efficacy and safety of complementary alternative medicines (CAMs) have not been demonstrated and further studies are required. SSRIs, SNRIs and gabapentin are effective in reducing vasomotor symptoms in short-term studies. The long-term safety needs further evaluation. IMS Position Statement, February 2007
