The role of corticosteroids in acute migraines is ill-defined. Although used in patients with intractable migraines, this class of medication is not widely used in typical migraine attacks. However, limited clinical data suggest that corticosteroids decrease the rate of recurrent headaches [19-21] and might decrease the pain of an acute attack [22]. Further research is needed to define the role of corticosteroids in the ED treatment of acute migraine headaches.
