Opsoclonus myoclonus induced by lamotrigine toxicity

It is known that Lamtrigine Lamotrigine (LTG) can cause paradoxal paradoxical drug-induced seizures especially in children with myoclonic epilepsy and is usually avoided in patients with severe myoclonic epilepsy of infancy (Dravet syndrome) [1]. However, LTG is considered quite safe and generally well-tolerated by healthy subjects with few side effects such as mild morbiliform morbilliform rash [1]. Recently, few cases reported in the literature showed that LTG can cause movement disorders, such as ataxia, tics, chorea, and dystonia [2,3].
