Zonisamide is a prescription sulfonamide anticonvulsant and carbonic anhydrase inhibitor that is proven to reduce seizures and control the disease for many dogs. This is a new generation of epilepsy medication that can be used alone or as an add-on drug. If your dog suffers from epilepsy or has had problems with other epilepsy drugs, talk to your veterinarian about the benefits of Zonisamide. It is important to work closely with your veterinarian to manage the disease effectively. Consistency when administering medications is crucial, as well as regular monitoring and checkups.
