### Information for Pet Owners * **Expected Effects:** This medication is commonly used to treat allergies and itching. It may cause your pet to become drowsy or sleepy. * **Cats:** While dogs usually get sleepy, cats may occasionally experience the opposite effect and become hyperactive or excited. * **Administration:** If you are using a sustained-release (long-acting) product, **do not crush the pill or allow your pet to chew it**. The contents of sustained-release capsules may be sprinkled on food, but must be eaten immediately before they dissolve. * **Human Products:** Chlorpheniramine is an FDA-approved human medication often found over-the-counter. Only use the exact product and dose recommended by your veterinarian, as many human cold/allergy products contain additional ingredients (like decongestants or pain relievers) that can be highly toxic to pets.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。
