Background Various antihistamines have been used in the management of feline atopic dermatitis, with variable reported benefit. To date, there have been no randomized, double‐blind, placebo‐controlled, crossover clinical trials on the use of this drug class in cats. Hypothesis/Objectives To evaluate the clinical efficacy of cetirizine hydrochloride for the control of pruritus and dermatitis in cats diagnosed with atopic dermatitis. Methods In this randomized, double‐blind, placebo‐controlled crossover clinical trial, 21 client‐owned cats diagnosed with mild to moderate nonseasonal atopic dermatitis were randomly assigned to two groups. Cats in each group received either 1 mg/kg cetirizine hydrochloride or placebo once daily per os for 28 days followed by a 14 day wash‐out period. Treatments were then crossed over, and cats received placebo or cetirizine hydrochloride for another 28 days. Owners marked a pruritus severity scale before inclusion in the study and weekly throughout the entire study period. Lesions were scored by the clinician using a C anine A topic D ermatitis E xtent and S everity I ndex ( CADESI )‐03 modified for the cat before enrolment and at day 28 of each treatment. Results Nineteen cats completed the study. There were no statistically significant differences between treatment with cetirizine hydrochloride and placebo for modified CADESI ‐03 or pruritus scores. Conclusion and clinical importance This study suggests that cetirizine hydrochloride cannot be recommended for the management of feline atopic dermatitis.
