What Is an Iodine Allergy?

Iodide contrast agents are commonly used clinically for kidney, gallbladder, bladder, bronchus, cardiovascular, and cerebral angiography. All iodine-containing contrast agents can cause allergic reactions when injected into the body. The symptoms vary in severity, and they can be severe and fatal. Allergy tests must be performed 1-2 days before the angiography, and those who are negative can only be used for iodine contrast examination. Iodine allergy tests can help prevent or reduce contrast agent reactions.

1. Oral or oral test: Yes

It should be noted that the contrast agent allergy test results are only of reference value, and a positive result does not predict that an allergic reaction will occur, nor can it predict the severity of the reaction. Negative results also have the potential for serious reactions, including lethal reactions. Allergy tests can also cause severe allergic reactions.

The main products are: Youweixian (iopromide), Onipak (iohalol), diatrizoate, sodium diatrizoate, iodinated oil, etc. Note in the 2000 edition of "Clinical Medication": A small number of patients have allergic reactions to iodine. Those who use this product for bronchogram, hysterosalpingogram and intramuscular injection should first do oral iodine allergy test. Fistula, sinus angiography, etc., iodized oil is not stored in the body, which can avoid allergy tests. The 2000 version of the "Clinical Medications" or the drug instructions clearly require iodine allergy tests before use, for the Uvexan (iopromide) and iohexol in the 2000 version of the "Clinical Medications" and the drug instructions do not explicitly Iodine allergy test.
