Logically, you cannot be allergic to all forms of iodine, IF that is what you reacted to in the contrast dye. Why? Because in order for you to be hyperthyroid in the first place, you have to be ingesting iodine. Iodine is THE critical ingredient in thyroid hormone, and without taking it into your body, every day of your life, you would have been massively HYPOthyroid.

Me again. What would some kind person sugget about this? About 20 years ago I had a kidney x-ray. The results were ok but I suffered an allergic reaction to the contrast dye they injected into me. At the time I don’t remember being told what was in the dye however most doctors I have spoken to assume it was the iodine in the dye which caused the reaction. I have told my endo about this but he still mentions RAI as a viable treatment option. In recent years, I have had a variety of CT scans – not associated with thyroid and each time, the docs have decided against using dye because of the iodine allergy. I would be reluctant to have RAI. What do you think?

Hi Kaitlin: I work in radiology, specifically CT scan as an RN. It has been my experience that people–and there’s a lot of them out there–who are allergic to the IV contrast have no problem with the RAI. There are different levels of allergic reactions to the IV contrast, so unless the reaction was extremely severe, even those with an iodine allergy can be given the dye provided they have received preparation with prednisone and benadryl. It is recommended that if someone has a CT scan with IV contrast dye, that they NOT have an iodine uptake test for several months afterward as the results of the uptake will not be accurate. Good luck. Noel
