A member asked:
What to do if i have allergy to iodine ( lugols/surg prep.) gastrografin needed for ct scan. is it safe for me to take?
A doctor has provided 1 answer
Allergy: It probably wouldn't be cross reactive with gastrograffin because the allergy is not really to the iodine atom. However, if there is concern, there are alternatives to gastrograffin. For example, a diluted barium preparation, which contains no iodine, is perfectly appropriate as a CT oral contrast agent under most circumstances
