Tartrazine (FD&C yellow #5) anaphylaxis: a case report.
Ann Allergy. 1981 Feb;46(2):81-2. PMID: 7469134
Tartrazine dye has been implicated in a variety of adverse reactions. There is a high correlation between aspirin sensitivity and tartrazine sensitivity but the reverse is exceedingly rare. Herewith is presented a case where repeated occult exposures to tartrazine yellow dye in a patient who could take aspirin with impunity was uncovered by a deduction. The ubiquitous nature and protean manifestations of dye sensitivity are discussed.
