Why is this medication prescribed?

Clozapine is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions) in patients who have not been helped by other medications or who have tried to kill themselves and are likely to try to kill or harm themselves again. Clozapine is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.

How should this medication be used?

Clozapine comes as a tablet and an orally disintegrating tablet (tablet that dissolves quickly in the mouth) to take by mouth. It is usually taken one to three times a day. Take clozapine 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. Take clozapine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Do not try to push the orally disintegrating tablet through the foil packaging. Instead, use dry hands to peel back the foil. Immediately take out the tablet and place it on your tongue. The tablet will quickly dissolve and can be swallowed with saliva. No water is needed to swallow disintegrating tablets.

Clozapine controls schizophrenia but does not cure it. It may take several weeks or longer before you feel the full benefit of clozapine. Continue to take clozapine even if you feel well. Do not stop taking clozapine without talking to your doctor. Your doctor will probably want to decrease your dose gradually.

Are there other uses for this medicine?

This medication should not be prescribed for other uses; ask your doctor or pharmacist for more information.
