Loratadine
別名: Clarityn, Claritin, Alavert
Loratadine is an antihistamine used to treat allergies. * **Administration:** Can be given with or without food. If vomiting occurs, try giving with a small meal. * **Toxicity Warning:** > **NEVER** give your pet a product containing a decongestant (like pseudoephedrine, often found in 'D' formulations like Claritin-D). These are extremely toxic to pets. * **Expectations:** It may take a few days of consistent use to see the full benefit for chronic skin allergies. It is generally less sedating than older antihistamines like Benadryl.
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。
