Olanzapine is indicated for the acute and maintenance treatment of schizophrenia and other psychoses where positive symptoms (e.g., delusions, hallucinations, disordered thinking, hostility, and suspiciousness) and/or negative symptoms (e.g. flattened affect, emotional and social withdrawal, poverty of speech) are prominent. Olanzapine also alleviates the secondary affective symptoms commonly associated with schizophrenia and related disorders.
Olanzapine is effective in maintaining the clinical improvement during continuing therapy in patients who have shown an initial treatment response.
Olanzapine is indicated for the treatment of moderate severe manic episode.
In patients whose manic episode has responded to Olanzapine treatment, Olanzapine is indicated for the prevention of recurrence in patients with bipolar disorder.
