DILANTIN® Infatabs® (phenytoin) Contraindications


DILANTIN is contraindicated in patients with:

  • A history of hypersensitivity to phenytoin, its inactive ingredients, or other hydantoins [see Warnings and Precautions (5.5)]. Reactions have included angioedema.
  • A history of prior acute hepatotoxicity attributable to phenytoin [see Warnings and Precautions (5.8)].
