In these trials, which had a median treatment duration of 12 weeks, the estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated.

It works on the brain to reduce the number and severity of seizures. Phenytoin is used to manage and prevent certain types of seizures, as well as to prevent and treat seizures that occur during or following neurosurgery. When serum level determinations are necessary, they should be obtained at least 5 to 7 half-lives after treatment initiation, dosage change, or addition or subtraction of another drug to the regimen so that equilibrium or steady-state will have been achieved.Phenytoin is extensively bound to serum plasma proteins.The plasma half-life in man after oral administration of phenytoin averages 22 hours, with a range of 7 to 42 hours.Phenytoin is metabolized by hepatic cytochrome P450 enzymes CYP2C9 and CYP2C19.
