Introduction
Learn what Lennox-Gastaut syndrome is, how clobazam helps manage LGS seizures, its benefits, side effects, precautions and how treatment is monitored.
Lennox-Gastaut syndrome (LGS) is a rare and severe form of epilepsy that usually begins during childhood. It is characterised by multiple seizure types, developmental difficulties, and seizures that can remain difficult to control despite treatment.

For patients and caregivers, managing LGS often requires long-term medical supervision and a combination of anti-seizure medicines. One medicine that may be prescribed as part of this treatment is clobazam, a benzodiazepine that helps reduce excessive electrical activity in the brain.
Understanding how clobazam works, when it may be prescribed, and what precautions are necessary can help patients and caregivers better understand epilepsy management.
What Is Lennox-Gastaut Syndrome?
Lennox-Gastaut syndrome is a developmental and epileptic encephalopathy associated with multiple seizure types, abnormal electroencephalogram (EEG) patterns, and varying degrees of cognitive impairment.
The condition can affect learning, behaviour, communication, and everyday independence. Some patients require ongoing assistance with daily activities.
Unlike certain forms of epilepsy that respond well to a single medicine, LGS can be particularly challenging to manage. Patients may continue experiencing seizures despite receiving multiple anti-seizure medications.
Common Seizure Types Associated With LGS
| Seizure Type | Description |
|---|---|
| Tonic seizures | Muscles suddenly become stiff, sometimes causing falls. |
| Atonic seizures | Muscle tone is suddenly lost, potentially causing head drops or falls. |
| Atypical absence seizures | Brief episodes of impaired awareness. |
| Generalised tonic-clonic seizures | Loss of consciousness, muscle stiffening, and rhythmic jerking movements. |
These different seizure patterns can make treatment complicated. Neurologists consider seizure type, frequency, medical history, and previous treatment response when developing an individualised treatment plan.

Why Is Lennox-Gastaut Syndrome Difficult to Treat?
LGS is frequently associated with drug-resistant epilepsy, meaning seizures may continue despite appropriate treatment with multiple anti-seizure medicines.
The underlying causes can vary. Some patients develop LGS following a brain injury, genetic abnormality, or another neurological disorder. In other cases, the cause remains unknown.
Frequent seizures can increase the risk of falls, injuries, and emergency situations. Developmental and behavioural difficulties may also affect quality of life.
Another challenge is balancing seizure control with medication side effects. Some anti-seizure medicines may cause drowsiness, dizziness, or behavioural changes.
When existing treatment does not provide sufficient seizure control, a neurologist may consider additional medicines, including clobazam.
What Is Clobazam?
Clobazam is a benzodiazepine medicine that acts on the central nervous system.
It is used in certain epilepsy treatment plans to help reduce seizure activity. In particular, clobazam is an established add-on treatment for seizures associated with Lennox-Gastaut syndrome.
Clobazam is available under different brand names. Fribi 10mg Tablet is a brand of clobazam listed by Hamna Pharmacy in Pakistan.
Although different brands may contain the same active ingredient, patients should verify the prescribed strength, formulation, and instructions with a pharmacist or doctor before switching between products.
How Does Clobazam Work?
Clobazam enhances the activity of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the brain.
GABA helps regulate electrical activity by reducing the likelihood that nerve cells will become excessively active.
Clobazam enhances GABA's effects at GABA-A receptors, increasing inhibitory signalling in the central nervous system.
In simple terms, it helps the brain regulate excessive electrical signals that may contribute to seizures.
However, clobazam does not cure Lennox-Gastaut syndrome or remove its underlying cause. Its purpose is to help manage seizure activity as part of a broader treatment plan.
How Is Clobazam Used in Lennox-Gastaut Syndrome?
Clobazam is generally prescribed as an adjunctive or add-on treatment.
This means it may be used alongside other anti-seizure medicines when existing treatment does not provide adequate seizure control.
The US Food and Drug Administration (FDA) approves clobazam for the adjunctive treatment of seizures associated with Lennox-Gastaut syndrome in patients aged two years and older.
The treatment decision depends on the patient's medical history, seizure patterns, previous medication response, and other individual factors.
Clobazam and Other Anti-Seizure Medicines
LGS treatment frequently involves multiple medicines because seizures may not respond adequately to a single drug.
| Medicine | General Role in LGS |
|---|---|
| Valproate | Commonly used as an initial anti-seizure treatment. |
| Lamotrigine | May be considered when initial treatment is insufficient. |
| Clobazam | Add-on benzodiazepine used to help control seizures. |
| Rufinamide | Additional treatment option for selected patients. |
| Topiramate | May be included in an individualised treatment plan. |
| Cannabidiol | An option for certain patients with LGS. |
These medicines are not interchangeable, and this table does not represent a recommended treatment sequence. A neurologist determines the appropriate treatment based on the patient's circumstances.

What Are the Potential Benefits of Clobazam?
The primary treatment goal is to reduce seizure frequency and severity.
For patients with Lennox-Gastaut syndrome, improved seizure control may help reduce seizure-related injuries and support better daily functioning.
Potential benefits include:
- Reduced frequency of seizures associated with LGS.
- Additional seizure control when existing medicines are insufficient.
- An additional treatment option for difficult-to-control epilepsy.
- The ability to incorporate clobazam into an existing anti-seizure treatment plan.
However, treatment response varies between patients. Some may experience meaningful improvement, while others may experience limited benefits or side effects.
Regular medical follow-up is necessary to evaluate whether the treatment remains appropriate.
Clobazam Side Effects and Safety Precautions
Clobazam affects the central nervous system and may cause unwanted effects.
Common Side Effects
Potential side effects include:
- Sleepiness or drowsiness
- Fatigue
- Dizziness
- Drooling
- Constipation
- Irritability or behavioural changes
The severity of these effects may vary depending on the patient, prescribed dose, and other medicines being used.
Dependence and Withdrawal
Clobazam belongs to the benzodiazepine family. Continued use can lead to physical dependence.
Clobazam should not be stopped suddenly without medical supervision.
Abrupt discontinuation or rapid dose reduction may cause withdrawal symptoms and worsening seizures. A doctor may gradually reduce the medicine when discontinuation is necessary.
Drug Interactions
Combining clobazam with opioids, alcohol, or other sedating substances may increase the risk of excessive sedation and respiratory depression.
Patients should inform their healthcare professional about all prescription medicines, over-the-counter products, and supplements they use.

How Is Clobazam Treatment Monitored?
Regular monitoring helps determine whether clobazam is providing meaningful improvement.
| Monitoring Area | Why It Matters |
|---|---|
| Seizure frequency | Evaluates treatment effectiveness. |
| Seizure severity | Helps assess changes in seizure-related risks. |
| Daytime alertness | Identifies excessive sedation or fatigue. |
| Behaviour and development | Helps monitor changes in daily functioning. |
| Medication interactions | Identifies potential treatment risks. |
Caregivers may find it helpful to maintain a seizure diary recording seizure dates, duration, observed movements, and recovery time.
This information can help the neurologist assess the patient's response and determine whether treatment adjustments are necessary.
Frequently Asked Questions
Is clobazam used for Lennox-Gastaut syndrome?
Yes. Clobazam is an established add-on treatment for seizures associated with Lennox-Gastaut syndrome.
Is Fribi 10mg a seizure medicine?
Fribi 10mg contains clobazam, a benzodiazepine that may be prescribed as part of an epilepsy treatment plan.
Does clobazam cure epilepsy?
No. Clobazam helps manage seizure activity but does not cure epilepsy or eliminate the underlying cause of LGS.
Can clobazam be taken with other epilepsy medicines?
Yes. It may be prescribed alongside other anti-seizure medicines, but the combination must be selected and monitored by a healthcare professional.
