Using Clemastine, Generic Tavist for Dogs and Cats

An Antihistamine Used for the Treatment of Certain Allergies

By Sam Bourne. August 05, 2013

indications for Clemastine

Clemastine is an antihistamine that blocks the h1-receptor, preventing certain allergens from entering the body. Essentially, it plugs up the holes that allergens get in through, making your cat or dog impervious to the adverse effects of these pesky little particles. This drug can help deal with most swelling or itching caused by a reaction to histamines. An Ethanolamine-based drug, this allergen suppressant has minimal, if any, effect on the user’s heart rate or stomach acid, making it a milder choice in comparison to other similar drugs.

Precautions

Clemastine should not be given to pets with a known sensitivity to antihistamines. Patients having trouble urinating, or suffering from glaucoma or heart failure should be administered Clemastine with added caution. It should not be given if the patient is currently on CNS depressants or MAOIs. While this drug is available over the counter, since it was initially designed for human use, and giving it to a cat or dog is considered extra-label usage, a veterinarian should be consulted before administering.

Dosage

Cats and Dogs
.05 mg/kg orally every 12 hours

Side Effects

CNS depression, paradoxical hyperactivity, dry mouth, redness of the skin, and possible diarrhea (in cats) can be a result of taking Clemastine.
