Typically hives, but can rapidly progress into anaphylactic shock. Reactions are usually mild. Please see the above link regarding Iodine-based contrast material.
All the best.
A severe reaction is your throat swells and you can't breathe. Minor reactions include hives or nausea and vomiting.
Throat tightness and unable to breathe.
