A Brazilian group has found acupuncture to be effective in decreasing hot flushes and menopause symptom scores in postmenopausal women. In a randomised, single-blind, placebo-controlled cross-over trial, 81 patients were assigned to two groups: Group 1 received 12 months of acupuncture, followed by six months of sham-acupuncture, while Group 2 received six months of sham-acupuncture, then 12 months of acupuncture treatment. After six months women in Group 1 exhibited significantly lower menopause symptom and hot flush intensity scores than those in Group 2. After 12 months, menopause symptom and hot flush scores were similar in both groups. After 18 months, the menopause symptom and hot flush scores for the women in Group 2 for were lower than those of the women in Group 1.

A multicentre randomised clinical study of menopausal women has concluded that acupuncture carried out in addition to usual care is associated with marked clinical improvement in hot flushes and other menopause-related symptoms. One hundred and seventy five Korean women were randomised to receive 12 sessions of acupuncture over four weeks in addition to usual care, or to usual care alone. The mean change in the average 24 hour hot flush score was -16.57 in the treatment group compared with -16.93 in the control group, a significant difference. Scores for psychological, somatic and urogenital symptoms of menopause also showed significant improvement in the acupuncture group compared with the control group.

A Norwegian study has found that acupuncture in addition to self-care can contribute to a clinically relevant reduction in menopausal hot flushes. The research was a multicentre, pragmatic, randomised, controlled trial with two parallel arms comparing the effect of individualised acupuncture plus self-care against self-care alone for hot flushes and health-related quality of life in 267 postmenopausal women. Hot flush frequency decreased by 5.8 per 24 hours in the acupuncture group and 3.7 per 24 hours in the control group. Hot flush intensity decreased by 3.2 units in the acupuncture group and 1.8 units in the control group. The acupuncture group also experienced statistically significant improvements in vasomotor, sleep, and somatic criteria compared with the control group.

A pilot study on the effect of acupuncture in decreasing hot flushes in menopausal women has concluded either that there is a strong placebo effect or that both traditional and sham acupuncture significantly reduce hot flush frequency. Fifty-six postmenopausal women (aged 44 to 55) were randomised to one of three treatment groups: usual care, sham acupuncture (shallow needling at non-therapeutic sites) or TCM acupuncture. The TCM acupuncture group received one of four treatments based on a TCM diagnosis. There was a significant decrease in mean frequency of hot flushes between weeks one and eight across all groups, although the differences between the three groups were not significant. However, the two acupuncture groups showed a significantly greater decrease than the usual care group, but did not differ from each other.

Acupuncture is associated with a significant decrease in the severity, but not the frequency, of postmenopausal hot flushes. In a randomised, placebo-controlled pilot study, 29 postmenopausal women averaging at least seven moderate to severe hot flushes per 24 hours, were randomised to receive seven weeks (nine treatment sessions) of either active acupuncture (standardised, individually-tailored point prescriptions) or placebo acupuncture (non-penetrating placebo needles at sham acupuncture points). Those receiving active treatment had a significantly greater reduction in hot flush severity than those receiving placebo. There was no significant difference in the reduction of hot flush frequency between the active and placebo groups, however both groups experienced significantly fewer episodes of flushing.
