How does ZYPREXA work?
A3: Diseases that affect the brain, such as schizophrenia and bipolar I disorder, are thought to be caused by certain chemicals in the brain being out of balance. Although it is not entirely clear how antipsychotic medications work in the body, it is believed that ZYPREXA works by adjusting the imbalance of chemicals in the brain that may cause symptoms of these conditions. By doing so, ZYPREXA may help restore more normal thinking and mood.
