Absence of Iodinated Contrast Hypersensitivity and Characterization of Gadolinium Utilization in an Interventional Pain Population.

Our results suggest that ICM-associated hypersensitivity is very rare during epidural procedures and the incidence is significantly lower than expected based on reaction rates during intravascular administration. This may be related to both dose as well as route of administration. The establishment of a protocol for safe workup of ICM allergy labels would be useful in optimizing pain procedures.
