Chlorpheniramine is an antihistamine medication that is commonly used in veterinary medicine to treat allergies in dogs and cats. It works by blocking the effects of histamine, a substance that is released by the body in response to allergens, and helps relieve symptoms such as itching, sneezing, and runny nose.


  • Relieves symptoms associated with allergies

Side effects:

  • Drowsiness or sedation is a common side effect of chlorpheniramine

  • Some pets may experience dry mouth at higher doses and may drink more water

  • Gastrointestinal upset, including vomiting, diarrhea, or loss of appetite, may occur in some pets

  • In rare cases, an allergic reaction may occur, which can cause itching, swelling, or difficulty breathing


  • This medication can have a bitter taste - it is recommended to hide it in a small treat or piece of moist food for better acceptance

  • Antihistamines can synergize with Omega-3 fatty acid supplements for better itchy skin control. Consider adding the supplement to your cart for even better results.

It is important to follow the dosage and administration instructions provided by your veterinarian and to monitor your pet for any signs of adverse reactions. Some pets may be more sensitive to chlorpheniramine or may have underlying health conditions that make it unsuitable for use. If you notice any unusual symptoms or if your pet's condition worsens or does not improve, contact your veterinarian immediately.
