How ZYPREXA Works
ZYPREXA is a kind of medication known as an atypical antipsychotic. It belongs to a larger category of medications that affect the mind, called psychotropics. Antipsychotic medicines are psychotropic medications that treat the symptoms of psychotic disorders, such as schizophrenia. They may also be prescribed to treat acute mixed or manic episodes of bipolar disorder.

Antipsychotic Medicines


Antipsychotic medicines are believed to work by balancing the chemicals naturally found in the brain.

Antipsychotic medicines can be used to treat the symptoms of psychosis in schizophrenia, such as hallucinations and delusions, and may improve symptoms, such as fears and voices.

Antipsychotic medicines are also prescribed to treat acute mixed or manic episodes of bipolar disorder. They may improve such symptoms as sleep disturbances, irritability, racing thoughts, and anxiety. Some antipsychotic medications are also prescribed to help control ongoing symptoms.

When you start taking ZYPREXA, keep in mind that it can take several weeks before you notice a difference in the way you feel. The time it takes to experience the full effects of ZYPREXA may vary from person to person, depending on individual symptoms and the dosage prescribed.

It is important to take ZYPREXA the way your doctor has recommended — the right dose, at the same time, every day. Learn how to get the most from ZYPREXA.
