Clobazam may increase the risk of serious or life-threatening breathing problems, sedation, or coma if used along with certain medications. Tell your doctor if you are taking or plan to take: antidepressants; medications for anxiety, mental illness, and seizures; sedatives; sleeping pills; opioids such as codeine, fentanyl (Duragesic, Subsys), morphine (Astramorph, Kadian), or oxycodone (in Percocet, in Roxicet, others); or tranquilizers. Your doctor may need to change the dosages of your medications and will monitor you carefully. If you take clobazam with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care immediately: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.
Drinking alcohol or using street drugs during your treatment with clobazam also increases the risk that you will experience these serious, life-threatening side effects. Do not drink alcohol or use street drugs during your treatment.
Clobazam is used with other medication(s) to control seizures in adults and children 2 years of age and older who have Lennox-Gastaut syndrome (a disorder that causes seizures and often causes developmental delays). Clobazam is in a class of medications called benzodiazepines. It works by decreasing abnormal electrical activity in the brain.
Clobazam comes as a tablet and a suspension (liquid) to take by mouth, and as an film to apply on the tongue. It is usually taken once or twice a day, with or without food. Take clobazam at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
If you are unable to swallow the tablets whole, you may break them in half on the score mark or crush and mix them with a small amount of applesauce.
The liquid comes an adapter and two oral dosing syringes. Use only one of the two oral dosing syringes to measure your dose and save the second syringe. If the first oral syringe is damaged or lost, the second provided syringe may be used as a replacement.
To take the liquid, follow these steps:
To take the film, follow these steps:
If your doctor has told you to take more than one film per dose, wait until the first film has completely dissolved before applying the second film.
Your doctor will probably start you on a low dose of clobazam and gradually increase your dose, not more than once every week.
Some people may respond differently to clobazam based on their heredity or genetic makeup. Your doctor may order a blood test to help find the dose of clobazam that is best for you.
Clobazam can be habit forming. Take clobazam exactly as directed. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor.
Clobazam may help control your condition but will not cure it. Continue to take clobazam even if you feel well. Do not stop taking clobazam without talking to your doctor. If you suddenly stop taking clobazam, you may experience withdrawal symptoms such as new or worsening seizures, hallucinating (seeing things or hearing voices that do not exist), behavior changes, depressed mood, loss of contact with reality, restlessness, irritability, panic attacks, difficulty concentrating, anxiety, difficulty falling asleep or staying asleep, headache, blurred vision, eye sensitivity to light, uncontrollable shaking of a part of your body, fast heartbeat, sweating, muscle pain and stiffness, stomach or muscle cramps, nausea, diarrhea, or weight loss. Your doctor will probably decrease your dose gradually.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with clobazam and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or the manufacturer's website to obtain the Medication Guide.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Do not open the foil pouch for the film until right before you are ready to use it. Store clobazam in a safe place so that no one else can take it accidentally or on purpose. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Store clobazam suspension (liquid) in an upright position. Do not use any remaining liquid more than 90 days after first opening the bottle.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
