Migraine is common in children and is one of the most common etiologies of headache leading
to emergency room presentation in children. Despite this, few studies have investigated the
treatment of acute migraine headache in the emergency room. We will perform a prospective,
double-blind, placebo-controlled study of metoclopramide versus placebo in the treatment of
acute migraine headache. The primary outcome will be the number of subjects headache free at
two hours.
