Clobazam is available in Canada only by prescription.

Known as



Clobazam is currently used only in combination with another anticonvulsant medication. It can be effective against tonic-clonic, complex partial and myoclonic seizures. Clobazam is a useful addition to the anti-epileptic medications for people with refractory or difficult-to-control seizures.

How to Use

Take clobazam exactly as prescribed. It can be taken with food to minimize indigestion.

Side Effects

Common reactions to clobazam include drowsiness, dizziness, lack of coordination and fatigue (with a high dose at the beginning of treatment). Irritability and paradoxical excitement might occur. An allergic skin rash might appear. If any side effects persist or are severe, contact your physician. Tolerance may develop after one to six months of administration. Some patients cease to respond to the drug.


Used over a long period of high dosage, clobazam can produce physical as well as psychological dependence. Women should avoid using clobazam during the first trimester of pregnancy, as well as while breast feeding. Seniors are vulnerable to negative reactions. People who are predisposed to depression may become suicidal. Used with other central nervous system depressants (including alcohol), clobazam will increase sedation (drowsiness). If you have kidney and liver problems, inform your doctor. Do not stop taking clobazam abruptly.


Inform your doctor if you are taking other anti-seizure medications. Do not combine alcohol with this drug.

Missed Dose

Take the next dose as soon as you remember. Then resume your regular medication schedule.


Store at room temperature between 15°C and 30°C. Keep away from children, heat, light and moisture.
