First seen Dec 26, 2025 · Last updated May 13, 2026 · Updated 21 times
Summary
This study compares a 1-hour versus a 4-hour intravenous premedication regimen to prevent allergic reactions to CT contrast dye in emergency patients with a known allergy. About 540 adults with a documented contrast allergy who need an urgent CT scan will be randomly assigned to one of the two protocols. The goal is to see if the shorter regimen is just as safe and effective, potentially speeding up critical imaging.
