# Clobazam (Oral)
## Overview
Clobazam is a 1,5-benzodiazepine with anticonvulsant properties. It is typically used as adjunctive therapy for seizures associated with Lennox-Gastaut syndrome (LGS) and other seizure disorders.
## Primary Indications
* Adjunctive therapy for seizures associated with Lennox-Gastaut syndrome (LGS) in patients 2 years of age and older.
* May be used for other seizure types based on clinical judgment and local protocols.
## Adult Dosing
* **Lennox-Gastaut Syndrome:** Initial dose: 5 mg twice daily. Titrate by 5-10 mg every week based on response and tolerability, up to a maximum of 20 mg twice daily.
* **Other Seizure Types:** Dosing varies significantly. Consult specific guidelines or local protocols.
## Pediatric Dosing (2 years and older)
* **Lennox-Gastaut Syndrome:** Initial dose: 5 mg twice daily. Titrate by 2.5-5 mg every week based on response and tolerability, up to a maximum of 10 mg twice daily for patients weighing less than 30 kg, and 20 mg twice daily for patients weighing 30 kg or more.
## Dose Adjustments
* **Hepatic Impairment:** Use with caution. No specific dosing recommendations are established, but lower doses and slower titration may be warranted.
* **Renal Impairment:** Use with caution. No specific dosing recommendations are established, but lower doses and slower titration may be warranted.
## Contraindications
* Known hypersensitivity to clobazam or other benzodiazepines.
* Severe respiratory insufficiency.
* Severe hepatic insufficiency.
## Adverse Effects
Common adverse effects include somnolence, sedation, constipation, diarrhea, decreased appetite, fatigue, drooling, and ataxia. Serious adverse effects include severe skin reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis), respiratory depression, suicidal behavior or ideation, and withdrawal symptoms.
## Key Drug Interactions
* **CNS Depressants (e.g., opioids, alcohol, other benzodiazepines, sedatives, hypnotics):** Increased risk of profound sedation, respiratory depression, coma, and death.
* **CYP2C19 Inhibitors (e.g., fluconazole):** May increase clobazam concentrations.
* **CYP2C19 Inducers (e.g., rifampin):** May decrease clobazam concentrations.
* **Certain Antiepileptic Drugs (e.g., stiripentol):** Coadministration with stiripentol can significantly increase clobazam concentrations.
## Monitoring
* Monitor for seizure frequency and type.
* Monitor for signs of somnolence, sedation, and cognitive impairment.
* Monitor for behavioral changes, including suicidal ideation or behavior.
* Monitor for signs of withdrawal upon discontinuation.
* Consider therapeutic drug monitoring if adherence is a concern or if interactions are suspected.
## Clinical Pearls
* Clobazam is often used as an add-on therapy.
* Taper gradually when discontinuing to avoid withdrawal symptoms.
* Risk of serious skin reactions requires patient and caregiver education on early signs.
* Patients should be advised against driving or operating heavy machinery until they know how clobazam affects them.
