What this medicine is used for
For the control of status epilepticus, tonic-clonic (grand mal), psychomotor seizures and the prevention of seizures occurring during or following neurosurgery. Phenytoin will prevent or effectively decrease the incidence and severity of convulsive seizures in a high percentage of cases, with patients exhibiting little tendency to become resistant to its action. Besides its effectiveness in controlling seizures, phenytoin frequently improves the mental condition and outlook of epileptic patients. It has also been used in the treatment of certain cardiac arrhythmias, particularly in those patients who do not respond to conventional antiarrhythmic agents or to cardioversion. Phenytoin serum level determinations may be necessary for optimal dosage adjustments (see DOSAGE AND ADMINISTRATION)
