Note(s)This section has been translated automatically.
Due to its "pyrazolone-like" structure, it can lead to pseudoallergic reactions in people who are predisposed. However, tartrazine does not act as a cyclooxygenase inhibitor. In a larger study with proven food allergy sufferers (type I sensitisations), a urticarial reaction with Tatrazine could be induced in 1% (after administration of 0.1-10mg Tartrazine). Under provocation there was an increase in plasma and urinary histamine as well as increased prostaglandin excretion. Patients with atopic diathesis tolerate tartrazine comparable to non-atopic patients (Pestana S et al. 2010).
Asthmatic reactions after tartrazine have been described several times (Jäger L et al. 2001). Contact sensitisation has been demonstrated in a few individual cases.
Since July 20, 2010, foods containing tartrazine must bear the following statement on the label: "May impair activity and attention in children".
