Cetirizine
別名: Zyrtec, Piriteze, Zirtec
**Cetirizine** is an antihistamine commonly used to help manage allergic skin disease, itching, and sometimes respiratory allergies in pets. * **Administration**: Can be given with or without food. If your pet vomits after taking it, try giving the next dose with a small treat or meal. * **Side Effects**: Generally very well tolerated. Mild sleepiness, drooling, or occasional vomiting may occur. If your pet seems excessively drowsy, contact your veterinarian. * > **CRITICAL WARNING**: Only use plain cetirizine. **Never** give your pet "Zyrtec-D" or any product containing decongestants like pseudoephedrine. These ingredients are extremely toxic and potentially fatal to dogs and cats. * **Allergy Testing**: If your pet is scheduled for allergy skin testing, ask your veterinarian when you should stop giving this medication beforehand, as it can interfere with the test results. * **Cost**: While generic options are available, it may be more expensive than older antihistamines like Benadryl.
