Allergies

Braclet

07/19/2000

Question:

From your response, I am not sure exactly then what to term the episode I had it it wasn`t "allergic". According to the MD after the CAT Scan, it was the iodine in the constrast dye that caused my situation. So...from the info you gave me, what would I put on the braclet that I am "allergic" to - constrast dye?

Answer:

You should put "Radiocontrast Media Allergy" on the bracelet. Technically, this is not an allergy as individuals with this problem do not produce specific allergic antibodies to the radiocontrast media. It is an allergic- like reaction and the end result is the same as if it were an allergic reaction. If you do need to have a procedure in the future requiring radiocontrast media, they should use low osmolality material and pre-treat you at least 13 hours before the procedure with Prednisone 50mg every 6 hours up until one hour before the procedure. You should also take Benedryl 50mg one hour before the procedure. This is a published protocol for pre-treatment of patients with radiocontrast media reactions. The reaction is not due to the iodine in the radiocontrast media.
