Effect of diphenhydramine and cetirizine on immediate and late phase cutaneous allergic reactions in healthy dogs: a randomized, double-blinded crossover study.

CONCLUSION AND CLINICAL SIGNIFICANCE: In conclusion, oral cetirizine was effective in preventing cutaneous allergic reactions without any obvious adverse effects in dogs. Oral DPH failed to show an inhibitory effect despite attaining plasma drug concentrations that are considered effective in people. PMID: 31899570 [PubMed - as supplied by publisher]
