Drug | Injection

Control of seizures (especially status epilepticus), prevention and treatment of seizures during neurosurgery, acute management of epilepsy when oral therapy is not possible

Phenytoin stabilizes neuronal membranes by blocking voltage-gated sodium channels in the brain. This limits repetitive firing and spread of seizure activity.

Administer only by a trained healthcare professional. Given as slow IV injection/infusion with cardiac and blood pressure monitoring; IM use is generally avoided for phenytoin sodium due to tissue irritation. Dose is individualized and may require blood level monitoring.
