What Is Loratadine?

Loratadine (also referred to as Claritin) dosage is a second-generation antihistamine that prevents the release of histamine a chemical secreted by the immune system when a dog is exposed to allergens such as a pollen, dust or food. Histamine is an irritant that causes allergic reactions, inflammation, blood flow, mucus, watery eyes and itching.

Loratadine dose for dogs inhibits the activation of these responses by histamine, thus decreasing the common symptoms of allergy (sneezing, runny nose, coughing, and skin irritation).

It also has less chances of causing drowsiness, unlike older antihistamines. It can be suggested in veterinary practice in mild to moderate allergic dogs, but plain loratadine for dogs dosage should be used only, since combination agents with decongestants are detrimental. Always consult a veterinarian before giving it to your dog.

Can Loratadine Help Treat Dog Allergies?
