Loratadine, commonly known by the brand name Claritin, is an oral antihistamine medication. Although it was designed for people with allergies, with a veterinarian's guidance it can also be given to cats.
As with people, any substance the cat is allergic to triggers her immune system and causes her to sneeze, scratch or even have digestive problems.
Cats can have allergic reactions to fabrics (such as wool), substances (like flea collars or shampoos), certain foods, pollens, molds and--of course--fleas.
The usual dosage for cats is 5 mg every 24 hours. Always check with your veterinarian before giving any medication to your pet.
In addition to medication, your cat may benefit from a medicated shampoo or spray if the allergy is causing itching or hair loss, flea treatment if fleas are the cause, or the removal of a substance from the cat's diet or environment.
Duration of Treatment
If the trigger can be removed from the environment, treatment can be short-term. If the allergy is seasonal, your cat may only need the medication when the trigger, such as pollen, is active.
Always check with your veterinarian before changing your pet’s diet, medication, or physical activity routines. This information is not a substitute for a vet’s opinion.
