Antipsychotic drugs are chosen for the clinical treatment of geriatric psychiatric disorders, and the drugs are mainly recommended to use olanzapine, risperidone, quetiapine and others. Since the elderly have more somatic diseases, poor physical condition and more types of medications, the initial dose of antipsychotic drugs should be small, and the drug interactions should be considered while using the drugs, and the side effects of the drugs should be closely observed. Older adults often suffer from a variety of physical illnesses, so they also need to pay special attention to the possibility of drug-induced psychiatric symptoms. At the same time, regular monitoring of blood levels and regular rechecking of liver and kidney function, blood glucose, and routine blood tests are recommended along with antipsychotic medication for psychiatric disorders in the elderly.
