Key Finding
Acupuncture significantly reduced migraine attack frequency, migraine days, and pain intensity compared to sham acupuncture, waitlist, and flunarizine, with benefits lasting at least 3 months after treatment completion.
If you suffer from migraines, you know how much they can disrupt your daily life. Medications can help, but they aren't always the right fit for everyone and require taking pills every single day. Researchers wanted to find out whether acupuncture could offer lasting relief from episodic migraines — and importantly, whether that relief would stick around even after treatment ended.
A team of scientists conducted a systematic review and meta-analysis, meaning they gathered and analyzed data from 15 high-quality clinical studies on this exact question. They looked at how acupuncture affected the number of migraine days per month, the number of migraine attacks, and pain intensity scores — all measured three months after the acupuncture treatment course was completed.
The results were encouraging. People who received acupuncture had significantly fewer migraine attacks and fewer days with migraines compared to those who received sham (fake) acupuncture. When compared to simply waiting for improvement on their own, or taking a common migraine prevention medication called flunarizine, acupuncture produced meaningfully greater reductions in pain — differences large enough to matter in real, everyday life, a threshold researchers call the "minimal clinically important difference."
Perhaps most importantly, these benefits lasted at least three months after treatment ended. This suggests acupuncture doesn't just provide short-term relief during the treatment period — it may actually produce durable changes that help prevent migraines over time.
While researchers note that more long-term studies are still needed, this review adds strong evidence that acupuncture is a viable, lasting option for people looking to reduce how often and how severely migraines affect them.
If you're considering acupuncture for migraine prevention, speak with a licensed and board-certified acupuncturist who has experience treating headache disorders.
This systematic review and meta-analysis (15 RCTs; databases searched through November 2022) evaluated the durable post-treatment effects of acupuncture on episodic migraine, with primary outcomes assessed at 3 months post-treatment: monthly migraine days, monthly migraine attacks, and VAS pain scores. Risk of bias was assessed using the Cochrane RoB 2.0 tool.
Acupuncture demonstrated statistically significant superiority over sham acupuncture in reducing migraine attack frequency (MD -0.68; 95% CI -0.93 to -0.43; p<0.001), migraine days (MD -0.86; 95% CI -1.18 to -0.55; p<0.001), and VAS score (MD -1.01; 95% CI -1.30 to -0.72; p<0.001). Compared to waitlist and flunarizine, acupuncture produced pain intensity reductions that exceeded the minimal clinically important difference (MCID), with MDs of -1.84 and -2.00 respectively.
Clinical takeaway: Acupuncture provides clinically meaningful migraine prophylaxis with effects persisting at least 3 months post-treatment, supporting its use as a durable non-pharmacological intervention.

📌 A non-linear dose-response analysis found that 16 acupuncture sessions delivered three times per week over approximately two months produced the greatest reduction in migraine attack frequency, with diminishing benefits beyond this threshold.
📌 Cupping therapy was associated with an 83% higher likelihood of treatment success in migraine patients (RR 1.83, 95% CI: 1.52–2.21), with wet cupping demonstrating the strongest effect.
