Consumer:Using phenytoin together with cloZAPine may decrease the effects of cloZAPine. Contact your doctor if your condition changes. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: Several case reports suggest that phenytoin may reduce steady-state plasma concentrations of clozapine. Worsening of clinical status has been reported. Data exist for phenytoin, but this interaction may also occur with other hydantoins. The mechanism is unknown, but may be induction of CYP450 hepatic metabolism by phenytoin.
MANAGEMENT: If a hydantoin and clozapine must be used together, close observation for clinical and laboratory evidence of altered clozapine effect is recommended, especially when initiating, changing dosage, or discontinuing the hydantoin.
