Droperidol for the Treatment of Acute Migraine Headaches

Objective: To evaluate the safety and efficacy of droperidol for the relief of acute migraine headaches. Data Sources: A MEDLINE search (1946 to August 2014) was performed using the following keywords and associated medical subject headings: droperidol, inapsine, headache, migraine, and migraine disorder.Study Selection and Data Extraction: The search was conducted to identify randomized controlled trials comparing droperidol with placebo or an active control in adult patients with acute migraine headaches that were published in English. Primary end points included acute headache improvement after the intervention. Safety end points included the frequency of extrapyramidal symptoms, somnolence, and cardiac adverse effects. Data Synthesis: In all, 5 manuscripts are included in this review. Patients presenting to the emergency department with acute headache desire rapid pain relief, which was the primary objective in each of the evaluated studies. Droperidol was better than placebo and at least as effective as comparator drugs such as prochlorperazine, meperidine, or olanzapine using droperidol doses of 2.5 to 5 mg, given either intramuscularly (IM) or intravenously (IV). The most commonly reported adverse effects were extrapyramidal symptoms and sedation. Cardiac adverse effects were not reported in any of the studies; however, only 2 articles described using cardiac monitoring. Conclusions: Parenteral droperidol is an effective option for the treatment of acute migraine. The minimum effective dose is 2.5 mg given IM or IV. Clinicians must be aware of the risk for adverse events, select appropriate patients, perform EKG monitoring for patients at risk of QTc prolongation, and institute treatment if necessary.
