Question of the Day

Phenobarbital is a common first-line anticonvulsant in dogs and cats. However, it can cause hepatotoxicity, so it may not be selected in animals with underlying liver disease (i.e., hepatopathy).

The second-most commonly used anticonvulsant in dogs is potassium bromide, other commonly used agents include levetiracetam and zonisamide. Potassium bromide is not recommended in cats as it can cause a severe eosinophilic bronchopathy.
