Previous studies have provided evidence that administering steroids in addition to standard migraine headache treatment in the emergency department may reduce the recurrence of the headache within 24-72 hours. The standard migraine treatments in previous studies have been varied and include 5-HT receptor agonists, dopamine antagonists, dihydroergotamine, NSAIDS, and opioid analgesics. The steroids added to the standard treatment have been prednisone and dexamethasone (both IV and oral).
This is the first study to examine the combination of peripheral nerve block as the primary treatment of migraine followed by oral dexamethasone to prevent recurrence.
