Q

A 34-year old male with epilepsy has been prescribed phenytoin 100mg capsules at a dose of one capsule twice a day for the treatment of tonic-clonic seizures for the past 2 years. Due to an increase in frequency of seizures the consultant plans to add lamotrigine to the patient’s treatment regimen.

What is the most appropriate action regarding the interaction between phenytoin and lamotrigine?

  • increase the dose of lamotrigine to achieve therapeutic levels.
  • monitor for decreased efficacy of phenytoin due to potential decreased serum levels.
  • monitor for signs of phenytoin toxicity due to potential increased serum levels.
  • no action needed as there is no significant interaction between phenytoin and lamotrigine
  • reduce the dose of phenytoin before starting lamotrigine to prevent toxicity
A
  • increase the dose of lamotrigine to achieve therapeutic levels.
  • phenytoin lowers lamotrigine levels
