Migraine headaches are a common problem for children. When treatment at home fails, children
may benefit from intravenous treatment administered in a hospital setting like the Emergency
Department. Most treatments used however have only been tested in adults and the best
treatment strategy for children is not always clear. The combination of more than one
medication is frequently prescribed in Canadian Emergency Departments. The purpose of this
study is to investigate whether the combination of ketorolac (an anti-inflammatory pain
medication) and metoclopramide (an anti-nauseant that may also relieve migraine headaches) is
better than metoclopramide by itself.
