Clobazam

Clobazam is a benzodiazepine anticonvulsant / anxiolytic medicine available in Bangladesh under many brand names. Below are its uses, side effects and precautions — and every brand with its current price.

Doctors prescribe Clobazam for:

• Epilepsy — adjunctive treatment: added to other anti-seizure medicines when seizures are not fully controlled, in adults and children over a specialist-decided age, including in Lennox-Gastaut syndrome
• Catamenial (menstruation-related) seizures — sometimes used intermittently around the period, on specialist advice
• Severe acute anxiety — short-term use only, when a doctor judges a benzodiazepine necessary

Clobazam is prescription-only and, in epilepsy, should be managed by a neurologist. It is not a medicine to start, stop or adjust on your own.

Common side effects of Clobazam:

• Drowsiness and sedation, especially at the start and after dose increases
• Dizziness, unsteady walking and poor coordination
• Slowed reactions, difficulty concentrating
• Drooling or dry mouth, constipation
• Irritability or behaviour changes, particularly in children
• Tolerance — the effect may lessen over months in some patients

Seek urgent medical help for: severe skin rash with blisters or peeling (rare but serious reactions are reported with clobazam), breathing difficulty or very shallow breathing (especially if combined with opioids or alcohol), worsening seizures, severe confusion, or signs of dependence such as craving and self-increased doses.

Key precautions with Clobazam:

• Dependence warning: benzodiazepines are the most misused medicine class in Bangladesh. Even in epilepsy, where longer use is medically justified, take Clobazam only at the prescribed dose, never increase it yourself, and never share it.
• Never stop abruptly — risk of rebound seizures and withdrawal; all changes must be tapered under medical supervision.
• No alcohol — it deepens sedation and can dangerously suppress breathing.
• Driving caution: do not drive or operate machinery until you are sure of your alertness — and remember epilepsy itself carries driving restrictions.
• Tell your doctor about breathing problems, liver or kidney disease, depression, muscle weakness or any history of substance misuse.
• Report severe rash immediately, and attend regular reviews so the specialist can reassess benefit, dose and duration.

Tell your doctor about every medicine you take. Important interactions with Clobazam:

• Alcohol — markedly increases sedation and clobazam levels; strictly avoid.
• Opioid painkillers (tramadol, morphine, codeine) — combined use can severely suppress breathing.
• Other anti-epileptics — interactions with valproate, phenytoin, carbamazepine, stiripentol and cannabidiol may change drug levels; specialists adjust doses accordingly.
• Strong CYP2C19 inhibitors (such as fluconazole, fluvoxamine, omeprazole) — can raise the active metabolite of clobazam and deepen sedation.
• Other sedatives — sleeping pills, sedating antihistamines, antipsychotics and some antidepressants add to drowsiness.

Clobazam must not be used in:

• Allergy to Clobazam or other benzodiazepines
• Severe respiratory failure or sleep apnoea syndrome
• Myasthenia gravis
• Severe liver disease
• History of dependence on alcohol or drugs, unless within a supervised treatment programme
• For the anxiety indication, it is not used in the first trimester of pregnancy and in very young children

Specialist judgement is required in the elderly and in anyone with chronic breathing problems or depression.

Pregnancy: Clobazam should be used in pregnancy only when the specialist judges it essential — for example, when stopping it would risk uncontrolled seizures, which are themselves dangerous for mother and baby. Benzodiazepines near delivery can make the newborn floppy, sleepy and slow to feed, and regular use can cause withdrawal symptoms in the baby. Never stop abruptly on discovering a pregnancy; contact your specialist the same day to review the plan.

Breastfeeding: Clobazam passes into breast milk and may sedate the infant. Breastfeeding is generally not recommended during treatment; if it is attempted under medical advice, the baby must be watched closely for sleepiness and poor feeding.

Store Clobazam below 30°C in a dry place, away from light and moisture, in its original packaging. As a benzodiazepine with misuse potential, keep it securely stored, out of the reach of children and of anyone it was not prescribed for. Do not use after the expiry date, and return unused tablets to a pharmacy — do not keep leftovers at home or give them to others.
