CEREBYX® (fosphenytoin sodium) Contraindications


CEREBYX is contraindicated in patients with:

  • A history of hypersensitivity to CEREBYX or its inactive ingredients, or to phenytoin or other hydantoins [see Warnings and Precautions (5.6)]. Reactions have included angioedema.
  • Sinus bradycardia, sino-atrial block, second and third degree A-V block, or Adams-Stokes syndrome because of the effect of parenteral phenytoin or CEREBYX on ventricular automaticity.
  • A history of prior acute hepatotoxicity attributable to CEREBYX or phenytoin [see Warnings and Precautions (5.8)].
  • Coadministration with delavirdine because of the potential for loss of virologic response and possible resistance to delavirdine or to the class of non-nucleoside reverse transcriptase inhibitors.
