Allergy to Ivp Dye
Posted over a year ago
If there is an allergy to ivp dye is isovue safe to use?
Disablednurse - Ivp dye is an iodine based dye. If you have an allergy to IODINE or SHELLFISH,you CANNOT receive this iv dye. If you don,t, it should be ok. Ask the technician,at time of scheduling this,about this particular dye. They should be asking you questions about your allergies,if any,before they actually perform this test. Don,t be afraid to ask questions! I,m a nurse,but i always have questions. Good luck.
Kmurf - I was given IVP dye about 18 yrs ago when I had a kidney stone.Within 2 minutes my face was swollen and my arm pits bobbled out.I was given a shot to counter act this.Dr.s told me to never get this med and wear a med braclet. I have aspine and shoulder injury and the Dr wants me to have a dye X-ray even though he knows my reaction to this.What do I do? Kathleen
Pharmacist123 - Dear DisabledNurse - this is not true. This is an urban legend. (and 'iodine' is not the same as 'iodinated'). See: http://www.sdirad.com/PatientInfo/pt_iodinated%20contrast.htm The Iodine Allergy Myth Some people that have a history of allergy to shellfish, a history of a previous reaction to IV iodinated contrast, or a history of a reaction to a topical iodine solution, have been told that they have "iodine allergy." This is actually not correct. "Iodine Allergy" doesn't really exist. Iodine is a substance essential to life and is found throughout your body like within thyroid hormone or in amino acids, your body's basic building blocks. The reactions experienced in each of these situations do not have to do with the presence of the iodine. Instead, in each case the reaction is to another substance. In the case of shellfish, the reaction is to tropomyosin, a muscle protein. In the case of iodinated contrast, it is the other portion of the contrast molecule, not the iodine. In the case of topical iodine solution, it is to other substances in the solution, not the iodine itself. Shellfish allergy is not a contraindication to iodinated contrast because the allergy is entirely unrelated. This is a longstanding myth even within the medical community and is difficult to dispel. To some degree, asthma will increase the possibility of a contrast reaction. Sensitivity to Betadine® and other Iodine-containing solutions is unrelated to reactions to iodinated radiographic contrast agents.
Maureens - In response to disablednurse and pharmacist. I agree with disablednurse regarding allergy to iodine or povidine may produce allergy to IV contrast for Cat Scan (but not MRI). I had surgery which resulted in using betadine across entire abdominal incision. Within a 24 hours my incision was reddened and I started to get hives in the area. It gradually spread from the incision until it was over my entire body. Bottom of my feet, between my fingers, scalp, back, legs. I saw a dermotologist who told me I had an allergic reaction to the betadine that developed systemically. He also said I should not receive IVP dye. Years later I needed a test requiring IV dye and took prednisone and benadryl as a prep. During the exam, my insides burned like crazy after the injection, especially my gut. Not the mild warm sensation, but a severe painful burning. Within 24 hours the skin on my fingers was peeling and in various places on my arms. Later another test, radiologist would not inject me because he said this was break through reaction. I'm sticking to the MRA. Too risky and no one can say for sure. signed nottakingchances
