About this trial
The IMPACT study is a randomized, double-blind clinical trial evaluating two commonly used intravenous medications - metoclopramide and acetaminophen - for treating acute post-concussion symptoms in emergency department patients after mild head injury. The study aims to determine which treatment more effectively improves symptoms such as headache, dizziness, nausea, concentration difficulties, and emotional changes within the first week after injury.
Participants will be enrolled across two Montefiore emergency departments and followed using a validated post-concussion symptom questionnaire. Findings from this study may help improve evidence-based treatment strategies for patients experiencing concussion-related symptoms after head trauma.
