Treatment of reactions to IV contrast
Treating Immediate-Type Reactions
- Oxygen at high dosage via face mask for respiratory, cardiovascular, and neurological reactions
- Antiemetic for nausea and vomiting (though these reactions are usually brief and self-limited)
- Antihistamines, such as ranitidine or diphenhydramine, for symptomatic urticaria, angioedema, or diffuse erythema
- Epinephrine for laryngeal edema, bronchospasm, and generalized or severe angioedema
- Corticosteroids are not useful for treating acute reactions; these may play a role in preventing delayed recurrences up to 48 hours.
- Although rare, cardiovascular and severe respiratory reactions may require emergency treatment and should be handled immediately according to hospital protocol.
