Does anyone have an allergy to contrast dye?

I had a scan done with IV contrast many years ago and the next day my body was covered in a bright red rash from neck to knees! Many years later, I had another scan done for something totally different. I told them of my "allergy" and the tech said not to worry because they now used non ionic dye. The next day, I was covered in a bright red rash from neck to knees. I am just trying to find out if there is any relationship between an allergy to IV contrast media and thyroid issues.

Re: Does anyone have an allergy to contrast dye?

That would be me. I am allergic to both iodine and cobalt. Thus I can not do the RAI tests. Why? Because if they do not use radioactive iodine they use radioactive cobalt. My mother was the same way. They doped her up with enough anti-histamines and steriods for a horse and she still went into anaphalaxis when her RAI was administered. She is well now, but the RAI testing about killed her. At least they had the specialist on hand and were prepared to treat this just in case. I bet you react to cheap jewelry too.. the kind with Nickle in it. This is a common grouping of allergens. I have no idea why. I have just seen it over and over in my thyroid disfunctional family. I wonder if it is actually linked to our thyroids? Humm something else for me to ponder.

Sincerely,
MG

Re: Does anyone have an allergy to contrast dye?

WOW! You are so right on! I have never been able to wear anything but 18 carat gold earrings! My ears get all red and filled with pus! In fact, I had some surgical steel screws put in my foot and the bone never healed...just kept swelling. It was found to be an allergy to the nickel content in the stainless steel screws. I now have titanium with no problem. AND....my mother had the same issue with the contrast dye. We never knew it until she got brain cancer and they did a scan. I had had the reaction long before so I knew immediately what it was. She was always very secretive about health issues and never really laughed or had a lot of friends.....MAYBE she had some sort of thyroid issue going on?? I wonder how many of us there are on this board?

Have you had any sort of allergy testing? I am just worried that one day I may need some test involving one of these agents and don't want to go through the reaction again. Hoppy (Thanks Midwest....I love the name!)

Re: Does anyone have an allergy to contrast dye?

you need to have testing done so that the allergic reaction can be documented. Each time you come into contact with the agent your reaction will amplify until you may have an anaphylactic response. If you do not have a medic alert bracelet you should invest in one. Mine has my drug and more serious allergens listed. It stays on my wrist day and night.

I have had three separate skin allergy scratch tests performed (various states mean one needs various allergy serums) and one week long contact allergen study performed by my dermatologist. The scratch tests showed various environmental allergens and food allergens including seafood (shrimp), mushrooms, strawberries, coconut, wheat, and I would have to dig out my list for the rest. The contact allergen study was performed by placing pastes of gels on little dime sized disks. These disks were affixed to tap sixteen to a strip of wide masking tape. Then the strip was taped to your back. It stayed in contact with your skin for 48 to 72 hours. Mine was placed on Monday and 9 am and removed Wednesday at 4 pm. No water or washing or scratching of your back allowed.. (and I so wanted to put my back up to a wall or post and rub like you see animals doing. ) The MD makes notes on what has reacted and the size then you get to wait another 48 hours Friday at 4 pm for me. Where they look over the spots again make finally notations and tell you what are your dominant allergens. I was allergic to iodine, cobalt, and nickle, he found the reaction impressive and the combination of all three very rare. Also allergic to formaldehyde, propylene glycol (this is in everything from your soap/shampoo/conditioner/deoderant to baked cakes and preserved meat!), some rare urea compounds that break down into formaldhyde as well.

As the month go by my allergies are getting worse. This and my mom finally telling me that she and her sisters and her grandmother had thyroid issues led me to crack down and request extensive thyriod testing as part of the second pregnancy planning phase.

As to jewelry I can only do gold, sterling silver, titanium and platinum as well. I had to get the titantium medic alert bracelet because the steel one caused my skin to fester under it. I am a bit curious as to those with thyroid issues having allergies to iodine, and cobalt as well. I wonder if it has to do with the dysfunction of or thyroids and if removing the thyroid would make it better.

Sincerely,
MG
