Cetirizine has not been proven safe to use in dogs or cats that may be pregnant or nursing.

In some cases, vomiting or hypersalivation has occurred after starting on Cetirizine. In some small dogs taking higher dosages, drowsiness has been reported.


Dosage: Cetirizine comes in tablet form and should be taken orally once a day.

For dogs, dosage is based off of their overall weight, the ratio being 1 mg of Cetirizine per kilogram.

Cats should be given somewhere between 2.5 - 5 mg of Cetirizine, never exceeding the 5 mg cap.

These dosages are only an educated estimate and a licensed vet should be consulted before starting any new drug regimen.
