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