A Phenytoin drug assay measures the concentration of this medication in your blood. Phenytoin (commonly known by brand names like Dilantin, Eptoin, or Epsolin) is an antiepileptic drug used to control certain types of seizures.
Like many seizure medications, Phenytoin has a “narrow therapeutic window.” This means the difference between an effective dose and a toxic dose is very small. Regular blood monitoring is essential to ensure the drug is working without causing dangerous side effects.
