Hot flashes affect about three fourths of postmenopausal women and are one of the most common health problems in this demographic group. Dysfunction of central thermoregulatory centers caused by changes in estrogen levels at the time of menopause has long been postulated to be the cause of hot flashes. Treatment should begin with a careful patient history, with specific attention to the frequency and severity of hot flashes and their effect on the individual's function. For mild symptoms that do not interfere with sleep or daily function, behavioral changes in conjunction with vitamin E (800 IU/d) use is a reasonable initial approach. For more severe symptoms, the next step is to determine whether there is a contraindication or a personal reservation to estrogen replacement therapy. For women who are able and willing to use estrogen, it will successfully relieve symptoms by about 80% to 90%. In patients with a history of breast or uterine cancer, treatment with the progestational agent megesterol acetate appears to be a safe alternative that also decreases hot flashes by approximately 80%. For women unwilling or unable to use hormone therapy, one of the newer antidepressant agents can be prescribed. Venlafaxine decreases hot flashes by about 60%. Gabapentin is another drug that appears promising as therapy for women unable or unwilling to use estrogen, and the results of ongoing trials to determine its efficacy are eagerly awaited. The use of clonidine, methyldopa, and belladonna should be discouraged because of their modest efficacy and adverse effects.

A growing body of evidence suggests that antidepressant therapies, particularly selective serotonin reuptake inhibitors and venlafaxine, are effective in the management of hot flash symptoms. Several of these agents have the support of the American College of Obstetricians and Gynecologists and the North American Menopause Society. To review the literature on antidepressants for the treatment of hot flashes in women, we searched the PubMed, International Pharmaceutical Abstracts, and MEDLINE databases from inception through May 2009. All publication types that included human participants and that were published in English were eligible for review. These articles, relevant abstracts, and additional references were used to collect pertinent data. Although initial small pilot trials were conducted solely in breast cancer survivors, additional studies have been conducted both in breast cancer survivors and in relatively healthy menopausal women. Data on the benefits with many of these agents are conflicting. Venlafaxine and paroxetine have been studied more extensively than any of the other antidepressants and are more consistent in effectively reducing the frequency and severity of hot flashes, based on these study results. Desvenlafaxine, sertraline, fluoxetine, and citalopram should be considered second- or third-line options if patients fail therapy with or cannot tolerate venlafaxine or paroxetine, based on the current published data. Duloxetine, escitalopram, fluvoxamine, and mirtazapine should be reserved as last-line therapy until more rigorous studies are conducted assessing their use in the management of hot flashes.

Toxicity due to treatment causes a negative impact on quality of life in breast cancer survivors. Hot flash symptoms, described as intense sensations of heat, sweating and flushing occur in more than 50 % of breast cancer patients taking tamoxifen. We hypothesized that venlafaxine, a selective-norepinephrine reuptake inhibitor drug, was effective for reducing patient-reported hot flash scores among women treated for breast cancer compared to other non-hormonal treatments. We searched Medline, Scopus, and Cochrane Central Register of Controlled Trials from inception till May 2015 for venlafaxine (75 mg once daily or greater) with non-hormonal comparators for the treatment of hot flashes in female breast cancer patients. The primary outcome was hot flash score (derived from patient-reported hot flash severity and frequency) in randomized controlled trials. Standardized mean differences (SMD) were calculated for each study due to variation in the outcome measures. Heterogeneity was determined using I (2) statistics, and publication bias was assessed using a contour funnel plot and Egger's tests. Pooled analyses demonstrated that venlafaxine significantly reduced hot flash scores compared to the trial comparators (overall SMD 2.06; 95% confidence interval (CI) [0.40, 3.72]). There was significant heterogeneity among these studies (I (2) = 98.7%, P < 0.001). Asymmetry in the contour funnel plot suggests the presence of publication bias and a trend towards small study effects (Egger's test, P = 0.096). Venlafaxine is efficacious in managing hot flashes among women with breast cancer. This review highlights methodological issues that arise from eligible trials and recommends a collaborative approach in survivorship studies.

Patient-centered decision making about hot flash treatments often incorporates a balance of efficacy and side effects in addition to patient preference. This systematic review examines randomized controlled trials (RCTs) comparing at least two non-hormonal hot flash treatments in breast cancer survivors. In July 2015, PubMed, SCOPUS, CINAHL, Cochrane, and Web of Science databases were searched for RCTs comparing active, non-hormonal hot flash treatments in female breast cancer survivors. Thirteen trials were included after identifying 906 potential studies. Four trials were dose comparison studies of pharmacologic treatments citalopram, venlafaxine, gabapentin, and paroxetine. Hot flash reduction did not differ by tamoxifen or aromatase inhibitor use. Citalopram 10, 20, and 30 mg daily had comparable outcomes. Venlafaxine 75 mg daily improved hot flashes without additional side effects from higher dosing. Gabapentin 900 mg daily improved hot flashes more than 300 mg. Paroxetine 10 mg daily had fewer side effects than 20 mg. Among four trials comparing different pharmacologic treatments, venlafaxine alleviated hot flash symptoms faster than clonidine; participants preferred venlafaxine over gabapentin. Five trials compared pharmacologic to non-pharmacologic treatments. Acupuncture had similar efficacy to venlafaxine and gabapentin but may have longer durability after completing treatment and fewer side effects. We could not perform a pooled meta-analysis because outcomes were not reported in comparable formats. Clinical trial data on non-hormonal hot flash treatments provide comparisons of hot flash efficacy and other patient important outcomes to guide clinical management. Clinicians can use the information to help patients select hot flash interventions.
