Premedication with steroids and Benadryl is recommended only for patients who have had a reaction to contrast of a similar class (iodinated agents used during CT are one class, gadolinium based agents used during MRI are separate class) to the one planned to be given. Prophylaxis for those with reactions to other allergens is no longer necessary.

From his extensive research, Elliot Lasser 1 has proposed a mechanism in which the large contrast-containing molecule causes an overload effect on the antigen-binding sites on immunoglobulin E (IgE) of mast cells and basophils and does not bind directly to an antigen-specific site.
