Treatment of childhood headache with dihydroergotamine mesylate.

This study was undertaken to determine whether pediatric patients with migraine without aura who have failed standard outpatient regimens including intravenous dihydroergotamine mesylate (DHE) in conjunction with oral metoclopramide would respond to an inpatient treatment protocol of intravenous DHE and oral metoclopramide. Thirty patients were evaluated in this study which was an open label, retrospective review of treatment. Independent of the duration of the refractory migraine, 80% of the patients responded to the protocol with only minimal side effect. The dose of DHE mesylate ranged from 0.1 to 0.5 mg. The dose of DHE is lower than is typically utilized in standard adult protocols. The patients received an average of five doses of DHE.
