Read our Schizophrenia research guide →This is an observational study that follows people with schizophrenia who are already taking or planning to take antipsychotic medications like quetiapine, olanzapine, risperidone, aripiprazole, ziprasidone, paliperidone, amisulpride, perospirone, or clozapine. Researchers will monitor your health and collect information about how well the medication works and any side effects you experience over three years. The study involves visiting a clinic multiple times to answer questions, get blood tests, and have your physical health checked.
Doctors want to understand how safe antipsychotic medications are when people take them for years, and which factors affect how well the treatment works for different patients. This information will help doctors choose the best medication and dosage for each person.

You will visit a clinic for check-ups at scheduled times over three years (visits at specific weeks: 0, 4, 8, 13, 26, 52, 78, 104, 130, and 156 weeks). At each visit, you'll have a physical exam, blood tests, blood pressure check, and answer questions about your symptoms, mood, and how the medication is affecting you. Researchers will also review any side effects and take an electrocardiogram (heart rhythm test) to monitor your health.
