Olanzapine belongs to a group of medicines called antipsychotics and is used
to treat the following conditions:

things which are not there, mistaken beliefs, unusual suspiciousness, and
becoming withdrawn. People with this disease may also feel depressed,
anxious or tense.
• Moderate to severe manic episodes, a condition with symptoms of
excitement or euphoria.
Olanzapine has been shown to prevent recurrence of these symptoms in patients
with bipolar disorder whose manic episode has responded to olanzapine treatment.
