Abstract

BACKGROUND
Single premedication with antihistamines for radiocontrast media (RCM) hypersensitivity is frequently used in real world at the emergent situation although its efficacy is not proven.
OBJECTIVE
To evaluate the effect of intravenous antihistamines as a premedication in general population who had experience of mild adverse reactions to iodinated RCM.
METHODS
A retrospective observational study on 14,785 subjects who had RCM-enhanced computed tomography scans between January 2014 and December 2015 in Seoul National University Hospital Gangnam Healthcare Center, Seoul, South Korea.
RESULTS
Among 453 subjects who had a history of mild RCM-induced hypersensitivity reactions, 273 subjects had a single premedication of intravenous antihistamine. When comparing antihistamine-premedication group and nonpremedication group, there is no protective effect of antihistamines on the incidence rate and severity of hypersensitivity (10.6% vs. 11.7%, p = 0.729).
CONCLUSION
The clinical efficacy of a single premedication of antihistamines for mild RCM-induced hypersensitivity was not confirmed.
