Focus on frequency
Migraine prevention is different from treating an attack in progress. NCCIH summarizes studies in which acupuncture reduced migraine frequency, but the advantage over simulated acupuncture was small in some comparisons. A realistic consultation should discuss that uncertainty and ask how many migraine days you currently have, how you record them and what change would matter to you.
Keep established care visible
Tell the practitioner about prescribed prevention and rescue medicines, triggers you have noticed and any clinician's plan for new or changing symptoms. Acupuncture can be discussed as an additional option, but it should not displace a needed headache evaluation or abruptly replace medicines. Ask whether the practitioner has experience working with patients whose migraine care is medically managed.
Make a decision with a diary
Record migraine days, severity, lost activities and medication use before and during a defined trial. Reassess benefits, burdens and fees at the agreed point. An enthusiastic testimonial does not tell you whether the reviewer had migraine, tension headache or another problem, so use clinical evidence and your own tracked result.
Questions and answers
Does acupuncture prevent every migraine?
No. Studies show average effects, not guaranteed freedom from migraine for an individual.
