What is Vigabatrin 500 mg Tablet?
Vigabatrin 500 mg Tablet is a prescription medicine used to treat specific forms of epilepsy that have not responded adequately to other anti-seizure medications. It works by increasing the level of gamma-aminobutyric acid (GABA), a natural chemical in the brain that helps reduce abnormal electrical activity responsible for seizures.
Because Vigabatrin carries a risk of permanent vision loss, it is prescribed only when the expected benefits outweigh the potential risks. Patients receiving treatment require ongoing monitoring by a neurologist or other qualified healthcare professional.
Who is Vigabatrin prescribed for?
Vigabatrin may be prescribed for adults and children with certain seizure disorders, including:
- Refractory focal (partial) epilepsy
- Infantile spasms (West syndrome) when clinically appropriate
- Patients who have not achieved adequate seizure control with other antiepileptic medicines
It is not suitable for self-medication or routine treatment of every type of epilepsy.
How does Vigabatrin work?
Vigabatrin increases the concentration of GABA (gamma-aminobutyric acid) in the brain by blocking an enzyme called GABA transaminase. Higher GABA levels help calm excessive electrical signals between nerve cells, reducing the frequency and severity of seizures in eligible patients.
This mechanism makes Vigabatrin different from many other anticonvulsant medicines and explains why it is reserved for selected clinical situations.
What conditions does Vigabatrin treat?
The medicine is primarily used in the management of:
- Refractory focal epilepsy: For patients whose seizures remain uncontrolled despite other treatments.
- Infantile spasms: A serious childhood seizure disorder that requires early specialist treatment.
The exact treatment plan depends on the patient’s age, seizure type, medical history, and neurological evaluation.
How should Vigabatrin 500 mg be taken?
Always follow your neurologist’s instructions.
- General guidance includes:
- Take exactly as prescribed.
- Swallow the tablet with water.
- It may be taken with or without food.
- Take doses at the same time each day.
- Do not stop treatment suddenly unless advised by your doctor, as this may increase seizure risk.
Dose adjustments are based on clinical response and kidney function.

Early monitoring helps healthcare providers assess whether treatment should continue.
