About this study

Haloperidol is known to be a safe alternative medication to control difficult pain, and has been shown effective when compared to placebo for controlling headaches. Investigators hypothesized that the combination of haloperidol and diphenhydramine would be a useful medication choice for migraine headache patients in the emergency department in comparison to a common migraine treatment regimen of metoclopramide and diphenhydramine.

Read the detailed description

Investigators conducted a prospective, double-blind, randomized controlled trial in migraine patients who presented to an academic emergency department between June 2013 and November 2013. Research data was derived from an IRB approved protocol. All subjects met IHS migraine criteria and received a one liter bolus of normal saline plus 25 milligrams (mg) of diphenhydramine. Subjects were subsequently randomized to receive 10 mg metoclopramide or 5 mg haloperidol IV. Pain was self-reported at onset and at 20 minute intervals using a 100mm visual analog scale (VAS). Adequate pain control was considered to be patient satisfaction with symptomatic relief. If adequate pain relief was not obtained after 80 minutes, rescue medication was given at the treating physician's discretion. Adverse reactions were recorded and electrocardiograms (ECGs) were obtained before and after study medication administration. Follow up phone surveys were performed 72 hours after discharge to assess headache recurrence, adverse effects, and patient satisfaction.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain scores on the visual analog scale

    Measured: 20, 40, 60, and 80 min after administration of medications, and then again at the 48-72 hour mark

Secondary outcomes (1)
  1. Nausea and restlessness scores on the visual analog scales

    Measured: 20, 40, 60, and 80 minutes s/p administration of medications, and again 48-72 hours later

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Haloperidol, Metoclopramide 10mg and Diphenhydramine in people with Migraine Headaches and Nausea, run by United States Naval Medical Center, Portsmouth at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 29 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain scores on the visual analog scale (time frame: 20, 40, 60, and 80 min after administration of medications, and then again at the 48-72 hour mark). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2025.
