Phenytoin Sodium is an anti-epileptic drug prescription drug (also called an anticonvulsant) used to prevent and control seizures. Phenytoin Sodium belongs to the group I antiarrhythmics and hydantoin anticonvulsants drug classes. Group 1 antiarrhythmics are sodium-channel blockers, which block the fast sodium channels, thereby slowing the electrical conduction in the heart. While hydantoin anticonvulsants are structurally related to barbiturates. They have an allantoin heterocyclic base. Hydantoins slow the synaptic transmission by blocking sodium channels from recovering from the inactivated state and inhibit neurons from firing. This stops the repeated excitation of cells that results in seizures.

Common side effects of Phenytoin Sodium include drowsiness, confusion, slurred speech, abnormal eye movement, or problems with balance or muscle movement. Some people have thoughts about suicide while taking this medicine, Phenytoin Sodium can also make birth control pills less effective.
