Zyprexa is used to manage and treat schizophrenia, a complex mental disorder characterized by symptoms such as hallucinations, delusions, thought disturbances, and impaired social interaction. The drug improves these symptoms by restoring the balance of certain chemicals in the brain, helping to stabilize the patient's psychological state.
Zyprexa is also used to treat bipolar disorder, particularly acute manic episodes. In this case, the drug helps calm severe mood swings and reduce the excessive brain activity that may accompany these episodes. The drug may be prescribed as part of the treatment of severe treatment-resistant depression when combined with other medications, such as antidepressants, for better results.
