Migraine headache has a 1-year period prevalence in the US of 11.7% and accounts for approximately 1.2 million migraine visits to US emergency departments per year . There are numerous studies that discuss treatment for migraine and other benign headaches within the emergency department (ED), however, there are very few that discuss specifically the use of intravenous fluids (IVF) for headache treatment. Many of these studies look at various options for treating migraine and other benign headaches: treatment options include dopamine antagonists, opioids, non-steroid anti-inflammatory drugs (NSAIDs), triptans, anti-epileptics and ergot derivatives. Comparisons have been done between many of these treatment options with dopamine antagonists appearing to be the most effective, compared to other treatments The dopamine antagonist with the most evidence and availability for benign headaches is prochlorperazine. Given that IVF administration is a common part of treatment regimen for benign headache patients in the emergency department and given the lack of randomized trials in adults, the investigators aim to study the use of IVF on pain reduction in headache patients in the adult ED. There has been one randomized trial in pediatrics that shows IVF may help in patients with migraines, whereas the adult literature has no randomized control trials and a review of data shows that fluids do not help relieve pain in migraine headache patients. This study will include both adult and pediatric patients presenting to the Emergency Department with complaint of benign headache.
