Objective:The aim of this study was to review case reports about adverse events of acupuncture or moxibustion treatments in Korea. Methods:Electronic literature searches were performed for adverse events of acupuncture or moxibustion treatments in Korea up to October 2009. Results:Sixteen case reports or case series were retrieved in total. Among them, 10 were reporting about acupuncture, 5 about pharmaco-acupuncture (3 bee venom acupuncture and 2 others), and 1 was reporting about moxibustion treatment. The incidence of adverse effects couldn’t be proven due to the lack of prospective studies. Conclusion:Acupuncture treatment seems to be one of the safer forms of medical interventions, when performed by skilled Korean medical doctors. However, prospective studies are necessary to reach conclusions about safety. In addition, a system for collecting and managing adverse effects of Korean medical interventions as well as a reeducation system for clinicians is needed.
