  2. Seizures in 9 of these 14 patients probably resulted from poor seizure control despite high phenytoin levels, but in 5 cases, attacks were attributed to phenytoin toxicity. The only factor that seemed to correlate with seizures was a serum phenytoin level over 30 micrograms/ml
  3. Phenytoin is an anti-seizure medication (anticonvulsant) used for preventing or treating generalized tonic-clonic (grand mal) seizures, complex partial seizures (psychomotor seizures), and seizures occurring during or after neurosurgery.It may be used alone or with phenobarbital or other anticonvulsants
