Olanzapine is an antipsychotic medication. It works by changing the actions of chemicals in the
brain.
Olanzapine is used to treat the symptoms of psychotic conditions such as schizophrenia and
bipolar disorder (manic depression) in adults and children who are at least 10 years old.
Olanzapine is sometimes used together with another medication called fluoxetine (Prozac,
Sarafem). This combination is also used to treat depression after at least 2 other medications have
been tried without successful treatment of symptoms.
Olanzapine may also be used for other purposes not listed in this medication guide.
