Zyprexa® (olanzapine) is a medication approved for treating mental illnesses such as bipolar disorder and schizophrenia. It can also be taken in combination with another drug (fluoxetine) to treat bipolar depression and treatment-resistant depression.
Available in the form of an oral tablet, Zyprexa is usually taken once a day. In clinical studies where this drug was taken for schizophrenia, people experienced improvements in their schizophrenia symptoms (including hallucinations and suspiciousness) and had fewer relapses. These studies also show Zyprexa to be effective for bipolar disorder treatment.
It is not entirely known how Zyprexa works for the treatment of schizophrenia or bipolar disorder. However, it is known that it blocks or lessens the effects of several chemicals in the brain. These brain chemicals (such as dopamine and serotonin) may be elevated in people with schizophrenia or bipolar disorder. Zyprexa is not a cure for these conditions; it only helps to control symptoms.
