ABSTRACT
Different drugs are used in the treatment of epilepsy and, like other drugs, may induce the occurrence of adverse effects, some of them so severe that the drug must be discontinued and replaced. Carbamazepine may lead to changes in the cardiovascular, respiratory, and neurological systems, and cases of induction of myasthenia gravis as a neuromuscular disorder have been described in the literature. This paper reports the case of a dog that developed demyelinating polyradiculoneuropathy, probably triggered by carbamazepine. The patient presented tetraplegia, absence of spinal reflexes in the four limbs, cervical weakness, decreased bilateral eyelid reflex and respiratory effort. Electroneuromyography showed signs of demyelination. This, therefore, is the first report of association between carbamazepine and demyelinating polyradiculoneuropathy in dogs.
