Clobazam: Brands, Price & Uses in Bangladesh

Clobazam is a benzodiazepine anticonvulsant used in the management of seizure disorders and, in some markets, anxiety. Its indications are classified below by strength of evidence.

Established / Approved Indications

• Adjunctive treatment of seizures associated with Lennox-Gastaut syndrome (LGS): Clobazam is approved as an add-on therapy (used together with other antiseizure medicines, not as a stand-alone treatment) for patients 2 years of age and older with this severe, drug-resistant childhood-onset epilepsy syndrome.

Guideline-Supported / Other Regulatory-Approved Uses

• Adjunctive therapy for other drug-resistant epilepsy syndromes: In several countries, Clobazam is also used, under specialist supervision, as add-on therapy for other types of partial and generalised epilepsy that have not responded adequately to standard antiseizure medicines.
• Short-term relief of anxiety symptoms: In a number of markets outside the United States, Clobazam is licensed for the short-term (generally no more than 2-4 weeks) symptomatic management of severe, disabling anxiety, when other measures have not been sufficient. It is not intended for long-term use in anxiety.

Off-Label Use

• Clobazam is sometimes used off-label, on specialist advice, for other seizure types (e.g., as adjunct therapy in refractory epilepsy syndromes beyond LGS) or for short-term management of alcohol withdrawal symptoms; such use should only be undertaken by, or in consultation with, a specialist physician.

The exact approved indications, dosage forms and prescribing status of Clobazam can vary by country; a physician should confirm the appropriate use for an individual patient.

Clobazam dosing must always be individualised by a physician and titrated gradually. Below is a general summary; the prescriber's instructions should always take precedence.

Lennox-Gastaut Syndrome (adjunctive seizure therapy)

Total daily doses above 5 mg are usually given in two divided doses per day. Doses may be titrated further only under continued physician supervision.

Short-Term Anxiety (where approved)

Where Clobazam is licensed for anxiety, a typical adult starting dose is low (e.g., 10-20 mg/day in divided doses), for the shortest duration necessary (generally no more than 2-4 weeks including tapering), based on physician assessment.

Discontinuation

Clobazam must never be stopped abruptly after regular use; the physician will taper the dose gradually (e.g., reducing the total daily dose by roughly 5-10 mg per week) to reduce the risk of withdrawal symptoms and, in patients with epilepsy, rebound seizures (see Precautions and Warnings).

As with all benzodiazepines, side effects of Clobazam are generally dose-related and most prominent when starting treatment or after a dose increase.

Common Side Effects

• Somnolence and sedation
• Drooling (particularly in children)
• Constipation
• Fever (pyrexia)
• Lethargy and fatigue
• Cough
• Aggression or irritability
• Ataxia (unsteady gait/coordination difficulty)
• Insomnia

Serious / Less Common Side Effects

• Serious skin reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) (see Precautions and Warnings)
• Drug reaction with eosinophilia and systemic symptoms (DRESS)
• Respiratory depression, especially with other CNS depressants (see Interactions)
• Blood disorders (e.g., anemia, low white cell or platelet counts)
• Mood changes, depression, hallucinations, or suicidal thoughts
• Physical dependence and withdrawal symptoms with abrupt discontinuation after prolonged use

Patients should seek prompt medical attention for any rash, unexplained fever, blistering/peeling skin, difficulty breathing, or thoughts of self-harm while taking Clobazam.
