My golden retriever was first prescribed Pyneobarbatol for his seizures and took it for approx. 2 weeks. He was still very sedated and we noticed that he had some effects that would resembel liver affect, We brought him to the vet and was told that he should stop taking this immediatly as his leiver enzymes were elevated. The vet prescribed Potasium bromide and that was two days ago. We see no noticible improvement he is lethargic, wont eat and is week. The vet said wait at least three to four days but we are getting more worried by the day. Will these side effects wear off soon?
