Background: Dysmenorrhoea is the most common gynaecological disorder among adolescents. Acupuncture is a treatment that has been shown to be effective for pain relief in a variety of conditions. We evaluated the effect of acupuncture in control of primary dysmenorrhea related pain.
 Materials and methods: In a randomized, double-blind, clinical trial study, 100 patients with primary dysmenorrhea were randomized to acupuncture (9 sessions over 3 months) or control group (placebo acupuncture). All subjects were allowed to receive usual medical care. Pain was rated on a Numerical Pain Score (0–10) at three months. Patients’ data were analyzed by t- test using SPSS software.
Results: This study showed significant effectiveness of acupuncture in control of primary dysmenorrhea pain after 3 months (p<0.0001). No complications or side effects were reported due to acupuncture.
Conclusion: Acupuncture was associated with relief of pain in patients with primary dysmenorrheal, and it is a safe and effective method in reduction of primary dysmenorrhea related pain.
