Disseminated Intravascular Coagulation (DIC) is a syndrome characterized by hemorrhage and microvascular thrombosis. This condition is common in critically ill patients and the most frequent causes are sepsis, trauma and malignancy. Lamotrigine is an anticonvulsant medication that has the effect of inhibiting the release of excitatory Neurotransmitters such as glutamate, by blocking sodium channels. The association between DIC and the use of lamotrigine has already been described in the literature, including pediatric patients, as a rare adverse event, which can be enhanced by the concomitant use of valproic acid, as it prolongs the half-life of lamotrigine by decreasing its hepatic clearance. The estimated incidence of lamotrigine hypersensitivity reactions ranges from 1 in every 1,000 to 10,000 exposed. The mechanism by which lamotrigine promotes this reaction in the host is not completely understood, but considering its potential for severity, it becomes a relevant topic for discussion. This study aims to describe a case of a child admitted to the Pediatric Intensive Care Unit (PICU) with DIC associated with lamotrigine.
