MONITOR: Influenza virus vaccine has been reported to exert a variety of effects on phenytoin pharmacokinetics. Both decreases and increases in phenytoin serum concentrations have both been reported. The mechanism is unknown.

MANAGEMENT: Close observation for clinical and laboratory evidence of altered phenytoin effect is recommended for at least 2 weeks after influenza virus vaccine is administered to a patient receiving phenytoin. Patients should be advised to notify their physician if they experience loss of seizure control or symptoms of phenytoin toxicity (e.g., drowsiness, visual disturbances, change in mental status, seizures, nausea, or ataxia).
