Cerenia is a medication that is used as an anti-inflammatory which works by blocking a neurotransmitter in the inflammatory cascade. Cerenia is labeled for dogs but commonly used in cats for nausea, vomiting, intestinal inflammation, bladder inflammation, allergic conditions, and arthritis. We have not seen any side effects, but according to literature it can cause twitching if overdosed.  The typical dosage for this medication is 4 mg once a day for 5 days and then every other day or twice weekly. It can be used with various other medications such as prednisolone to control inflammation. Due to the fact that the medication is bitter, we put it in gel caps so the cat does not taste the Cerenia.
