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)].
- 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.
