Chlorpheniramine is an antihistamine frequently used in dogs and cats with allergies or itching associated with certain types of skin hypersensitivity. It can also be prescribed to horses, ferrets and birds. The body’s immune system releases a naturally occurring chemical called histamine to protect the body by responding to triggers (allergens) such as insect stings, parasites, or pollen. Histamine works to remove the allergen and can cause inflammation or pain, increase heart rate, dilate blood vessels, and increase stomach acid production in the process. Pets can produce other chemicals similar to histamine that also contribute to allergic reactions, which is why antihistamines such as chlorpheniramine tend to be less effective in pets than in humans.
