After a mild delayed cutaneous reaction, preventative measures are not advocated for future contrast exposures. Late adverse reactions after intravascular iodinated contrast medium include symptoms such as nausea, vomiting, headache, itching, skin rash, musculoskeletal pain, and fever. 2 Citations. The pathophysiology of delayed cutaneous reactions is speculative but likely represents a spectrum of T cell-mediated delayed hypersensitivity . The most commonly reported late adverse reactions to iodine-based contrast media are headache, skin rash, itching, nausea, dizziness, urticaria, fever, arm pain and gastrointestinal disturbances. A prospective study was conducted by means of a questionnaire to determine the prevalence of delayed reactions to contrast media administered intravenously (iopamidol) and orally (diatrizoate sodium) in 170 patients who had received interleukin-2 (IL-2) and in 631 patients who did not. Iodinated contrast (IC) often is overlooked as a cause of delayed drug reactions. Contrast dyes containing iodine have been responsible for severe reactions (including deaths) in a very limited number of people. 65 Accesses. Immediate reactions take place within an hour after injection of the contrast medium. CONCLUSION. They are usually safe, and adverse effects are generally mild and self-limiting. We report an illustrative case of a delayed cutaneous reaction to IC and review the literature on the epidemiology and management of this underrecognized phenomenon. The aim of this prospective study was to determine the specificity and sensitivity of skin tests in patients who have experienced such reactions. Delayed rashes have been noted in 5% of patients undergoing urography. Non-immediate reactions to iodinated contrast media (ICM) consist mainly of cutaneous manifestations, such as maculopapular rashes, fixed eruptions, erythema multiforme, and urticarial eruptions. A follow-up study showed sim - ilar increased rates of DARs … Delayed cutaneous reactions to iodinated contrast.

Transient, nonpigmenting fixed drug eruption caused by radiopaque contrast media. Skin testing and radioallergosorbent testing (RAST) have not been shown to be helpful in the diagnosis. Most of these studies included retrospective cases tested years after the reaction, or lacked precise clinical history, name of culprit agent, or were mixed immediate and delayed reactions. Small test doses are often not helpful, with reports of severe, life-threatening reactions occurring after small amounts of RCM given, as well as severe reactions with larger doses of RCM occurring after a person tolerates a small dose of IV dye. These reactions can be mild (nausea, vomiting, mild urticaria, pallor), moderate (severe vomiting, extensive urticaria, dyspnea, rigor, laryngeal edema) or severe (pulmonary edema, cardiac arrhythmias or arrest, circulatory collapse).

In addition, iodinated contrast media have been shown to be responsible for delayed or non-immediate reactions that occur 1 h up to several days following iodinated contrast medium-injection. Patientsreceiving contrast media via IV typically experience a hot feelingaround the throat, and this hot sensation gradually moves down to thepelvic area.Reactions to IV dye are observed in 5%to 8% of patients who receive them. People, who have a history of any kind of reaction to iodine contrast, have a chance of encountering such problem in future. Allergic-type reactions can be immediate or delayed. A significant proportion of these reactions is unrelated to the contrast medium; however, allergy-like skin reactions are well-documented side effects of contrast media with an incidence of approximately 2%. The most frequent skin manifestations were urticaria, rashes, pruritus and limited facial edema. Sánchez-Pérez J, F-Villalta MG, Ruíz SA, García Diez A.
