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.
This will be a single center, prospective, single blinded randomized controlled trial on a convenience sample of patients presenting to the adult or pediatric ED with a chief complaint of headache. Subjects will only be enrolled when a physician or research assistant who is familiar with the study protocol is available to enroll patients. Written, informed consent will be obtained from each patient. Consent will include a discussion of the risks and benefits. In addition to parental informed consent in the pediatric population, age appropriate verbal assent will be obtained from pediatric subjects. After 30 minutes, the treating provider will be permitted to administer a "rescue medication" of their choice for further treatment. If there is an untoward event that requires the patient to know which IVF dose was administered, patient will unblinded and will not continue in the study.

Reduction in Pain Scores at 60 Minutes
The primary outcome measure will be the mean reduction in pain scores at 60 min. In other words the pain score at time zero minus the pain score at time 60 minutes. Pain scores are measured 0-100, with 0 being no pain and 100 being maximal pain, on a visual analog scale score. Higher numbers indicate more pain reduction.
Time frame: 60 minutes
Reduction in Pain Score at 30 Minutes
The mean reduction in pain scores at 30 minutes. This is calculated as the pain score at time zero minus the pain score at time 30 minutes. Pain scores are measured 0-100 on a visual analog scale score, with 0 being no pain and 100 being maximal pain. Higher numbers indicate more pain reduction.
Time frame: 30 minutes
Admissions
The difference between the rates of admission will be measured.
Time frame: 1 day
Reduction in Nausea Score at 60 Minutes
The reduction in mean nausea scores will be measured. This is calculated as the nausea score at time zero minus the nausea score at time 60 minutes. Nausea is measured from 0-100 on a visual analog scale with 0 being no nausea and 100 being maximal nausea. Higher numbers indicate more reduction in nausea.
Time frame: 60 minutes
Vomiting
The difference in the percentage of patients in each group who vomit within one hour after the treatment starts.
Time frame: 60 minutes
Rescue Medication
The difference between the percentage of patients requiring rescue medications for headache will be measured. "Rescue medications" are defined as any medication administered to the patient in the emergency department for their headache after the initial medications.
Time frame: 60 minutes
Percentage of Patients With Persistent Headache
The difference between the rates of persistent headache with telephone follow up.
Time frame: 24-48 hours after discharge.
