For the 5th time now issues have arisen about pt having "Iodine" allergy or remote allergy to IV contrast. A couple important issues that radiolog and techs are unaware of despite sending them sweet " I told you so pakcets of knowledge"
1-cant be allergic to iodine, thyroid makes it=dead
2-the US has moved to nonionic and low osmolar dye ie omnipaque
3-reactions were anaphylactoid secondary to hyperosmolarity of old dye
4- prior reaction does not increase risk of future reaction as again not IgE mediated anaphylaxis, but rather being anaphylactoid
5- premedication only effective and minimally at best, after 12 steroid doses
so in summary, do the damn scan, theyre not truly allergic, their risk is minimal, even if they have had a prior reaction. also ct dye nephropathy is coming under fire as not a thing, so be aware we may soon be able to skip BMP
