Radiographic contrast media are extremely valuable agents. The use of lower osmolality agents reduces the incidence of anaphylactoid but not nephrotoxic reactions. For repeated procedures in patients who have experienced previous anaphylactoid reaction to radiographic contrast media, the best results are obtained with 1) use of lower osmolality contrast media and 2) pretreatment with prednisone 50 mg at 13, 7, and 1 hour before the procedure and diphenhydramine 50 mg orally 1 hour before the procedure. Physicians should review emergency preparedness skills for themselves and their office or facility.
