Once-daily ethosuximide in the treatment of absence epilepsy.

ABSTRACT

Once-daily ethosuximide was used to treat 10 consecutive children with typical absence seizures. Three patients had gastrointestinal side effects which resolved when the same total daily dose was divided into 2 doses. Two other patients continued to have seizures on ethosuximide, whether given once or twice daily. Five patients had complete seizure control without adverse effects on once-daily ethosuximide.
