0.1% triamcinolone acetonide ointment and patch test responses.
The effect of topical steroids on patch test responsiveness was investigated in 15 subjects. A 0.1% triamcinolone acetonide ointment and a control preparation were applied three times daily to opposing sites on the upper part of the inner arms prior to patch testing. From a total of 18 pairs of patch tests applied to the 15 patients, substantial differences in the paired reactions were seen in only three patients after 96 hours. Of these, two had the more intense reaction on the control side, and the third had a greater reaction on the triamcinolone-pretreated side. Previously applied, intermediate-strength topical steroids are unlikely to prevent the detection of contact allergy by patch testing.
