Despite advances in treatment, patients with migraine have been underdiagnosed and undertreated. ⋯ In this emergency department population, many patients with migraine, chronic daily headache, or medication overuse are not accurately diagnosed. The need for prophylaxis is not usually assessed. Treatment is migraine specific in the minority of patients. Tension-type headache is rarely an accurate diagnosis in this emergency department population.

Studies in dogs showed that some hydroxymethylglutaryl coenzyme A reductase inhibitors (statins) are associated with cataract when administered in excessive doses. Clinical safety data of statins regarding cataract development in humans have been of limited value so far. ⋯ Our study provides evidence that long-term use of therapeutic statin doses does not increase the risk of developing cataract. Concomitant use of erythromycin and simvastatin may increase the cataract risk.
