Brief Summary
1-hour Premedication for Allergy Goal in Emergency: PAGE-1 is a prospective, parallel, two-arm, non-inferiority, randomized controlled trial evaluating the safety of a 1-hour (intervention) versus a 4-hour (standard regimen) intravenous (IV) premedication protocol in adult patients in the Emergency Department (ED) with a documented iodinated contrast allergy and requiring computed tomography (CT) imaging for a high-risk indication.
