Phenytek is a prescription medication approved by the Food and Drug Administration (FDA) more than 50 years ago for the treatment of seizures. In people with epilepsy, Phenytek is most effective for partial onset and tonic-clonic seizures. Phenytek may be referred to by its drug name, Phenytoin. Phenytoin is also sold under the brand name Dilantin.
Phenytek should not be used in people with Stokes–Adams syndrome or certain heart problems, including sino-atrial block, sinus bradycardia, and second- or third-degree atrioventricular blocks. Phenytek must be used with caution in people with a history of other heart problems, hypotension, liver damage, blood disorders, alcohol abuse, or porphyria. Phenytek may not be suitable for use by women who are pregnant or breastfeeding. Phenytek is not appropriate for people who have shown a past hypersensitivity to Phenytoin or other drugs in the same class, hydantoins. read more

A 2013 article reviewed existing studies comparing the effectiveness of Phenytoin (Phenytek) with that of Valproic acid (Depakene) for partial onset seizures or generalized onset tonic-clonic seizures. The review included five studies involving a total of 669 participants. Researchers did not find a statistical difference between the results for participants who took Phenytek or those who took Valproic acid.
