Intranasal Ketorolac Trial

The purpose of this study is to determine if intranasal (IN) Ketorolac in combination with oral Prochlorperazine and Diphenhydramine is non-inferior to current migraine management which involves use of intravenous (IV) Ketorolac and oral adjuncts Prochlorperazine and diphenhydramine for reducing pain intensity in children with migraine headaches. The investigators hypothesize that IN ketorolac combined with these oral adjuncts is non-inferior to IV ketorolac and oral adjuncts in reducing acute migraine headache pain by a minimum clinically significant difference within 60 minutes of administration.
