While most of the human patients developed PAE or CAE in the first 3 months of exposure to ZNS and resulted in discontinuation of ZNS within 5 months, some human patients developed PAE or CAE after many months after ZNS treatment was started, often in association with late dose increment of ZNS (24). In dogs, phenobarbital and bromide are considered first-line maintenance AEDs, but levetiracetam and zonisamide are often used as well. Bromide is generally well tolerated by dogs, but potential adverse effects include bitter taste, gastric irritation, nausea (particularly with the potassium form), polyuria, polydipsia, polyphagia, sedation, ataxia, and pancreatitis.
