Acupuncture (up to 15 sessions over 12 weeks) was compared with metoprolol (a standard migraine prophylaxis medication) for effectiveness and tolerability in 113 patients randomised to one of two groups. The number of days with Migraine decreased by 2.5 days in the acupuncture group compared to 2.2 in the medication group and those experiencing 50% or greater reduction in attacks was 61% for acupuncture and 49% for medication. Severe adverse effects occurred only in the medication group.
