To critically review the clinical trial evidence evaluating the efficacy of antihistamines in relieving pruritus in patients with atopic dermatitis.
Searched MEDLINE (1966–March 1999), the Cochrane Database of Systematic Reviews, and Best Evidence to identify clinical trials.
Identified 16 trials evaluating antihistamines in atopic dermatitis and graded them based on randomization, blinding, placebo controls, and statistical power.
Found zero grade A trials (large, randomized, double-blind, placebo-controlled trials providing definitive conclusions).
Identified three small randomized trials (grade B): two refuted the efficacy of antihistamines in relieving pruritus, and one supported efficacy.
Categorized the remaining 13 studies as grade C due to a lack of placebo controls, absence of randomization, or sample sizes under 20 patients per treatment arm.

Implication
