What is Phenytoin Sodium Injection?

What is Phenytoin Sodium Injection
Phenytoin is a hydantoin derivative used parenterally when rapid seizure control is required. It stabilizes neuronal membranes and reduces seizure activity by altering ion transport and decreasing synaptic transmission.
Therapeutic Uses of Phenytoin Injection
- Status epilepticus (emergency seizure control)
- Prevention of seizures during/after neurosurgery
- Tonic-clonic (grand mal) and partial seizures
- Traumatic brain injury-induced seizures
- Seizures associated with head trauma or craniotomy
How Phenytoin Injection Works
Phenytoin blocks voltage-gated sodium channels in the motor cortex, stabilizing neuronal membranes and reducing repetitive firing. This limits the spread of seizure activity and helps regain control during an epileptic episode.
Common Side Effects of Phenytoin Injection
- Drowsiness or dizziness
- Hypotension (especially with IV administration)
- Cardiac arrhythmias (requires ECG monitoring)
- Injection site reactions (e.g., phlebitis, “purple glove syndrome”)
- Nausea or vomiting
- Rare: Stevens-Johnson Syndrome (serious allergic reaction)
IV use must be administered slowly (not exceeding 50 mg/min in adults) with continuous cardiac monitoring.
