Phenytek is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to control generalized tonic-clonic (grand mal) and complex partial-onset seizures. Phenytek is also referred to by its drug name, phenytoin. Phenytoin is also sold under the brand name Dilantin.

Phenytek is an anticonvulsant, or in other words, a drug used to prevent and control seizures. It is believed to work in cases of epilepsy by inhibiting nerve signals in the brain.

How do I take it?
Prescribing information states that Phenytek may be taken either as emergency or maintenance medication. As an emergency medication, Phenytek may be administered intravenously. As a maintenance medication, Phenytek may be initiated with an intravenous loading dose, then taken orally as a capsule or liquid suspension every six to eight hours. In rare circumstances, Phenytek may also be injected intramuscularly.

Do not stop taking Phenytek suddenly. If you decide to stop taking Phenytek, consult your physician for a plan to reduce your dose gradually.

Phenytek should be taken exactly as prescribed by a physician.
