Allergic to Contrast

Inquiring about contrast allergies in advance is crucial to both patient safety and convenience. Please discuss this with your referring physician. Our standard protocol for IV contrast allergy premedication is oral prednisone 50mg (13, 7, 1 hour prior to injection) and a single dose of benadryl 50mg (1 hour prior to scanning). You must have a ride home if receiving benadryl.

If there are any indications that you may be prone to allergic reactions, we prefer to you to be scheduled at Mary Washington Hospital’s radiology department. This allows the highest level of supervision and medical support for any allergic reaction.
