When is premedication indicated prior to contrast administration?
The primary indication for premedication prior to contrast-enhanced imaging is the pretreatment of patients at increased risk for an acute allergic-like reaction to contrast material. Premedication generally involves the administration of corticosteroids, sometimes in conjunction with H1 blockers.
At our institution, indications for premedication include:
- • Prior moderate or severe allergic-like reaction to contrast material.
- • Prior intravenous contrast reaction requiring administration of epinephrine.
- • Prior life-threatening reaction to any allergen or medication.
- • Presence of asthma with active wheezing.
- • Presence of asthma requiring intubation in the last 3 months.
