Oculogyric crises secondary to lamotrigine overdosage.
We report four patients with no preexisting movement disorders who developed oculogyric crises secondary to lamotrigine toxicity and had resolution of these crises after dose reduction. Episode numbers ranged from 1-20 per day and episode duration from 2 s to several hours. Mean plasma concentration of lamotrigine at the time of oculogyric crisis was 15.5 μg/mL, with a mean dose of 16 mg/kg per day.
