ZYPREXA
Zyprexa (olanzapine) is an atypical antipsychotic available in oral and intramuscular (IM) formulations. It is indicated for the treatment of schizophrenia and bipolar I disorder, including acute manic or mixed episodes (as monotherapy or adjunct to lithium or valproate) and maintenance treatment. The IM formulation is specifically indicated for acute agitation associated with schizophrenia and bipolar I mania. Additionally, olanzapine is indicated in combination with fluoxetine for the treatment of depressive episodes associated with bipolar I disorder. Due to a higher risk of weight gain and dyslipidemia in pediatric populations, clinicians are advised to perform a thorough diagnostic evaluation and consider other medications first when treating adolescents (ages 13-17).
How ZYPREXA Works
The exact mechanism of action of olanzapine is unknown. Its efficacy in the treatment of schizophrenia is thought to be mediated through a combination of dopamine and serotonin type 2 (5HT2) receptor antagonism.

ZYPREXA Boxed Warning
INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled tri...
WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. ZYPREXA (olanzapine) is not approved for the treatment of patients with dementia-related psychosis [see Warnings and Precautions ( 5.1 ), Use in Specific Populations ( 8.5 ), and Patient Counseling Information ( 17 )] . When using ZYPREXA and fluoxetine in combination, also refer to the Boxed Warning section of the package insert for Symbyax.

ProIndications & Usage
FDA Label (PDF)ZYPREXA ® (olanzapine) is an atypical antipsychotic indicated: As oral formulation for the: Treatment of schizophrenia. Adults: Efficacy was established in three clinical trials in patients with schizophrenia: two 6-week trials and one maintenance trial. Adolescents (ages 13-17): Efficacy was established in one 6-week trial in patients with schizophrenia . The increased potential (in adolescents compared with adults) for weight gain and dyslipidemia may lead clinicians to consider prescribing other drugs first in adolescents. Acute treatment of manic or mixed episodes associated with bipolar I...
