Dilantin is a medication used to control seizures caused by epilepsy. It is also used to prevent seizures caused by brain surgery or head injury. Dilantin is the brand name for phenytoin, which belongs to a group of drugs called anticonvulsants. It works by stabilizing the electrical activity in the brain, which reduces the risk of having a seizure.
Uses
Dilantin is used to treat different types of seizures, including partial seizures, generalized tonic-clonic seizures, and complex partial seizures. It is also used to prevent seizures that may occur during or after brain surgery. Dilantin is sometimes used off-label to treat nerve pain caused by conditions such as trigeminal neuralgia.

Dilantin can be beneficial in controlling, reducing or preventing seizures. It may improve quality of life by reducing the frequency of seizures. Dilantin can also reduce the risk of sudden unexpected death in epilepsy (SUDEP) in patients with epilepsy.
