Two patients with prolonged postictal encephalopathy lasting 63 and 72
hours, respectively, following seizures with clozapine are reported.
Clozapine alters the EEG in a majority of patients treated, with seizure
frequency as high as 5-10% in doses above 600 mg/d. Prolonged postictal
encephalopathy following a clozapine-induced seizure has not been
previously reported but may be an important side effect of this medication.
Pharmacologic and clinical issues are discussed.Abstract Teaser
