Phenytoin (100mg)

Phenytoin (100mg) — Uses and Benefits

Phenytoin is mainly used to treat epilepsy and prevent different types of seizures.

WHAT THIS MEDICINE IS USED FOR

• Control of tonic-clonic (grand mal) seizures
• Control of complex partial (focal) seizures
• Prevention of seizures during and after brain surgery or head injury
• Treatment of status epilepticus (prolonged seizures) in hospital settings

HOW IT WORKS

• It stabilises the electrical activity of nerve cells in the brain
• It slows down abnormal, excessive nerve signals that cause seizures

• It is not a painkiller for general pain, only for certain nerve pain conditions when prescribed
• It is not used to treat anxiety, headache, or infections
• It is not a cure for epilepsy; it only controls seizures while being taken
