Zyrtec, or Cetirizine, is an antihistamine. Cetirizine helps reduce any allergen-related histamine-mediated irritation, pruritus preventing your body from sounding the allergy alarm coughing, itching, and sneezing. Since Cetirizine is a drug primarily intended for human use, and since there is no veterinarian-approved equivalent, Cetirizine for dogs and cats is considered an extra-label drug, or a drug being used outside its realm of approved use, even though it is commonly prescribed for pets by veterinarians.
