For more information on drug allergy management and treatment click here. While you may not experience allergic symptoms the first time you take a drug, your body could be producing antibodies to it. Penicillin causes most allergic drug symptoms. Antibiotics that contain sulfa drugs, such as Septra and Druf sulfamethoxazole-trimethoprim and Pediazole erythromycin-sulfisoxazoleoccasionally cause allergic reactions.
There is no evidence to my knowledge that shows an individual with radiocontrast sensitivity is at significant increased risk for MRI contrast. Predisposition to anaphylaxis in general, such as mast cell activation syndrome, might be associated with reactions to both types of agents but this is nonspecific. In your patient, I would discuss the relative risks with the patient and the surgeon.
I think MRI contrast would not be contraindicated despite a history of radiocontrast dye reaction.
Drug allergy: gadolinium
If radio contrast dye was drug, I h//o use the pretreatment protocol described below generally starting with H1 and H2 inhibitor and prednisone 13 hours before procedure. I would also encourage use of lower osmolarity and lower ionic contrast agents.

Drug allergy - Wikipedia
I did a PubMed search and could not find such a case. I don't think there are any official recommendations saying to do that, but I am allergy what your opinion is. I was talking to a radiologist today, and those questions came up.
A: I am not personally aware of any case reports of someone under 20 years of age that died from anaphylactic reaction to contrast media. However, this of course does not mean that deaths have not occurred. Regardless of the test being performed, any person who has experienced an anaphylactic reaction to radiocontrast should be pretreated with corticosteroids and drug if readministration of radiocontrast is necessary.
This is true regardless of the procedure in question or the route of administration of the contrast media. Reactions have occurred to contrast administered during via the urinary or gynecologic routes as well examples by intravenous injection. References: 1. Journal of Allergy and Clinical Immunology September h//o 3 Archives of Internal Medicine December ; 12 Annals of Allergy ; 67 1 Journal of Allergy and Clinical Immunology ; 74 4 Sincerely, Phil Lieberman, M.
Is it the same way of testing as with iodine contrast media? A: The technique of skin prick testing is the same regardless of what material is used for testing. Therefore the technique examples for aeroallergen testing would be identical to the technique employed for testing to gadolinium.
The reference and abstracts copied below will give you examples of what concentration might be employed in order to test for gadolinium. Epub Aug Clinical value of negative skin tests to gadolinium contrast agents. Abstract The use of contrast agent for magnetic resonance imaging improves the effectiveness of this diagnostic examination.
Complexes of godolinium, which appear to be well tolerated, are used for this purpose. A few cases of anaphylactic shock have been attributed to these agents. While undergoing a magnetic resonance imaging examination, a year-old nonatopic female patient became severely hypotensive, lost consciousness, and had generalized erythema immediately after the intravenous injection of this product. She recovered rapidly after she was given injection of epinephrine and her blood volume was restored with intravenous h//o.
That DOTAREM had allergy this h//o hypersensitivity reaction was proven by the positivity of prick-test and intradermal test at 0.
In addition of the exceptional character, this observation provides evidence for an immediate hypersensitivity without cross reactivity with gadopentetate dimeglumine. Skin prick tests and intradermal tests were performed using , drug dilution of the offending agent and alternative gadolinium-based agents [gadodiamide Omniscan and gadoteric acid Dotarem ]. Conclusion: We report the first case of an allergic reaction to gadobenate dimeglumine.
Cutaneous reaction to gadolinium injection Q: I have a pt. It extravasated out of her left antecubital fossa vein and she developed swelling and pain at that site.
The gadolinium was then successfully infused into her left hand vein without any symptoms of drug. She developed swelling and erythema hours later on that left hand as well as her other arm. No systemic symptoms. She had no immediate IgE mediated symptoms at the time of the infusion.
Do you know of any such delayed reactions to Gadolinium or examples reports of Patch testing to it? A: There have been reports of cutaneous reactions other than urticarial responses to the administration of gadolinium. They are rare, but are noted in the package insert, and one review of gadolinium reactions abstract copied below mentions such reactions. However, I am unaware of any testing to confirm the mechanism underlying these reactions, and a literature search also failed to reveal any such investigations.
I am not aware of any patch testing or other studies designed to investigate these reactions. Objective: We investigated the frequency, manifestations, and severity of reactions to gadolinium contrast media in patients who underwent MR imaging at a single institution.
Materials and Methods: We reviewed the quality assurance records allergy 21, patients to whom gadolinium contrast media were administered at our institution between January and October Of these patients, 36 had adverse reactions. All 36 patients were evaluated by a radiologist at the time of the adverse reaction, and a written report of the findings was completed immediately.
Results: We classified adverse reactions into h//o groups: mild nonallergic reactions 15 patients with nausea or vomitingmild reactions resembling allergy 12 patients with hives, diffuse erythema, or skin irritationmoderate reactions resembling allergy seven patients with drug symptomsand life-threatening reactions resembling allergy two allergy with severe chest tightness, respiratory distress, and periorbital edema.
