Chlorpheniramine Antihistamine for Pets

What is clorpheniramine?

Chlorpheniramine is in the class called antihistamines and is commonly used for allergies, itching, and as a sedative. It is commonly used in cats, dogs, and ferrets. No veterinary product is available that contains just clorpheniramine, thus the human product is dispensed. Some chlorpheniramine products are prescription, but the products sold by VetRxDirect are all over the counter.

When should clorpheniramine be avoided?

Chlorpheniramine shouldn’t be used in pets with closed angle glaucoma, BPH, hyperthyroidism, cardiovascular disease, hypertension, and COPD if they have mucous secretions, unless directed to use it by your pet's veterinarian.

What side effects does clorpheniramine cause?

Clorpheniramine can cause your pet to be sleepy, have a dry mouth, and urinate less frequently.

Chlorpheniramine is sold as an FDA approved generic drug. Brand varies from order to order and variation to variation. VetRxDirect is unable to guarantee which brand will be available at the time of order shipment.
