★Oxcarbazepine
First report of generalised seizures in children:3 case reports
Oxcarbazepine [dosages not stated] led to induction orexacerbation of seizures in three children.
Patient 1, a 13-year-old girl with a history of complex partialseizures, had her carbamazepine treatment changed tooxcarbazepine; she was also receiving phenobarbital.Approximately 3 months later, she developed eye-flutteringepisodes and an EEG revealed generalised spike and slow-wave activity. Oxcarbazepine was discontinued and her eye-fluttering resolved.
Patient 2, a 5-year-old girl with a history of left-sided focalseizures, had been receiving oxcarbazepine and valproic acidwhen valproic acid was discontinued. Within 2 months shedeveloped frequent generalised convulsive seizures and anEEG revealed frequent bursts of generalised spike and slow-wave activity. Oxcarbazepine was discontinued and replacedwith zonisamide and her seizures improved.
Patient 3, aged 10 years [gender not stated], had a history ofeye-fluttering episodes and generalised convulsive seizures.The patient’s treatment was switched from phenytoin tooxcarbazepine [duration of treatment not stated] and eye-fluttering increased markedly; clumsiness and confusion alsodeveloped. An EEG showed frequent generalised spike andslow-wave discharges. Following discontinuation ofoxcarbazepine and initiation of valproic acid treatment, thepatient’s overall functioning and eye-fluttering improved.
