Objective Acute migraine is associated with significant personal, economic and work‐related disability. Management guidelines advise the use of simple analgesia, triptans, chlorpromazine and anti‐emetics based on severity, with avoidance of opioids. We aimed to determine consistency of prescribing patterns in our ED with national guidelines. Methods We performed a retrospective cohort analysis of migraine presentations (ICD‐10‐AM G439) between 2012 and 2016. Exclusion criteria included migraine without headache, other primary headaches and secondary headaches. Demographic and prescribing data were extracted from medical records. Results have been reported as proportions. Results Of 4769 headache presentations, the application of exclusion criteria led to a total of 744 patients who received a migraine diagnosis (G439). Most were female (558/744, 75%), young (mean age 36.4 years) and had a self‐reported migraine history (558/744, 75%). There were 54 different medications prescribed. Paracetamol was more frequently prescribed (385/744, 52%) than aspirin (134/744, 18%). Opioid prescription occurred in nearly half of all presentations (345/744, 46%). Similar opioid prescriptions were also observed in those with a documented history of migraines (253/558, 45%). A minority of patients received triptans (51/744, 7%). Overall, a quarter of patients (189/744, 25%) received no guideline‐recommended medications. Conclusion We observed considerable polypharmacy in ED migraine management with inconsistent prescribing patterns. Recommended medications were infrequently used and opioid use was common. Factors influencing prescribing patterns require further investigation in order to improve rates of guideline recommended treatment.
