The existing evidence supports the value of acupuncture for the treatment of idiopathic headaches.
Due to the clinical heterogeneity and the poor methodological quality of the included studies, straightforward recommendations for clinical practice cannot be made. Overall, some forms of acupuncture seem to be beneficial, but it is unclear which treatment strategies (points, type of stimulation, frequency, etc.) and which providers may be most promising for particular groups of patients.
Though not risk‐free, acupuncture seems to be relatively safe in the hands of qualified providers. Therefore, we conclude that headache patients who want to try acupuncture should not be discouraged. Existing provision of acupuncture to headache patients also seems justified. Whether acupuncture should be more widely recommended and, if so, which particular type of acupuncture should be offered, are questions that cannot be answered at present.
