I have allergy to iodine and gastrografin needed for ct scan. is it safe?

Yes, but...: Reactions to contrast are usually not caused by a true allergy to iodine (which is rare). Low-ionic strength contrast should be used if you have a history of reactions to contrast, and the radiologist will give you antihistamines and corticosteroids (prednisone) before the test to help prevent a reaction. With this regimen, scans are usually very safe. Talk with the radiologist about your concerns.
