Risperidone

Risperidone ( ris-PER-i-done) is used to treat the symptoms of psychotic disorders, such as schizophrenia. Risperidone should NOT be used to treat behavioral problems in older adult patients who have dementia.

Risperidone 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). Risperidone is in a class of medications called atypical antipsychotics. It works by decreasing abnormal excitement in the brain.

Risperidone comes as a tablet, a solution (liquid), and an orally disintegrating tablet to take by mouth. It is usually taken once or twice a day with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Risperidone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Use the dropper provided to measure your dose of Risperidone oral solution. You can take the oral solution with water, orange juice, coffee, or low-fat milk. Do not take the solution with tea or cola. To take the orally disintegrating tablet, use dry hands to separate one blister unit at the perforation. Peel back the foil and remove the tablet. Do not push the tablet through the foil. Immediately place the entire tablet on your tongue but do not chew it. The tablet will quickly dissolve and may be swallowed with or without water. Your doctor will probably start you on a low dose of Risperidone and gradually increase your dose every day for several days, and then not more than once every week. Risperidone controls schizophrenia but does not cure it. It may take several weeks or longer before you feel the full benefit of Risperidone.

Continue to take Risperidone even if you feel well. Do not stop taking Risperidone without talking to your doctor. If you suddenly stop taking Risperidone, your symptoms may return and your illness may become harder to treat.
