Zyrtec For Fighting Allergies In Dogs

(redirects here from cetirizine)

The following information outlines the usage of cetirizine (Zyrtec) for dogs, including information about side effects, the correct dosage, safety precautions and more.


Zyrtec, the more popular name of the drug cetirizine, is a commonly used anti-allergen medication with fewer side effects than many other options on the market. Zyrtec blocks the H1 receptor to fight off common symptoms of allergic reactions. You should seek the approval of a vet before using this drug to ensure that it will be safe for your pet.

Zyrtec dosage for dogs

 
Never give Zyrtec to your dog without first consulting a vet. The usual dosages are as follows:

0 – 15 lb dog – 5 mg to be administered once a day.
16 – 39 lb dog – 10 mg to be administered once a day.
Dogs 40 lbs and over – 10 mg to be administered twice a day.

The exact dosage can change depending on the condition being treated.

Is Zyrtec safe for dogs?

 
Zyrtec is often considered safer than other popular anti-histamine drugs and usually produces few side effects. Unlike many other drugs of its class, Zyrtec does not pass into the CNS (central nervous system), and as such, many of the side effects associated with other similar medicines are absent when using cetirizine.


Safety precautions:

  • Seek veterinary approval before use
  • Do not use the decongestant formulation of this drug
  • Avoid use in pregnant dogs if possible
  • Check with the vet to ensure your dog’s symptoms are not being caused by something more serious
  • Notify the vet if your dog suffers from liver or kidney disease

Zyrtec is not FDA approved for use in dogs, but is often prescribed as an extra-label drug by vets for use in a variety of animals. Your dog should not experience many side effects when using this drug, though it is possible in rare cases. If unforeseen side effects present themselves you should seek medical advice straight away. Zyrtec has not yet been tested safe for pregnant or nursing dogs. Be sure that the formulation you are using contains only cetirizine as an active ingredient.

Hi, thanks for your comment. You should be aware that dogs aren’t humans. Dogs can tolerate some substances much better than humans, just like we can tolerate ibuprofen when our furry friends cannot. If you are uncertain you should consult with your vet, but that is a conservative dosage. This dosage is also recommended by an animal hospital:
