• While the prior application of triamcinolone acetonide to skin does not strongly influence patch test reactions, the presence of triamcinolone in the materials used for patch testing has a profound effect. Both irritant and allergic reactions to thimerosal are consistently negated when triamcinolone acetonide is present in concentrations of 0.1% and 0.025%.
