Understanding Claritin Use for Canine Allergies
Many pet owners don’t realize that the same antihistamine that relieves their seasonal allergies might also help their furry companions. Claritin (loratadine) can be an effective treatment for dogs suffering from allergies, but proper dosing is crucial for safety and effectiveness.
How Claritin Works for Dogs
Claritin is a second-generation antihistamine that blocks H1 receptors, reducing allergy symptoms like:
-
Itchy skin and paws
-
Watery eyes
-
Sneezing
-
Hives or skin rashes
Unlike first-generation antihistamines like Benadryl, loratadine causes less drowsiness because it doesn’t cross the blood-brain barrier as easily.
