Zyprexa is a medicine used to treat schizophrenia. This medication can also be used to treat manic or depressive episodes associated with bipolar disorder alone or in combination with lithium or valproate. Also, Zyprexa is used to treat episodes of depression that have not improved after taking two other medicines. Zyprexa is available in tablets or tablets that dissolve in your mouth called Zyprexa Zydis.
Zyprexa can be life-threatening when used in elderly people with mental problems caused by dementia (an illness involving loss of memory, judgment, and confusion). Zyprexa is not approved to treat mental problems caused by dementia.
Zyprexa can increase the risk of suicidal thoughts and behavior in children, adolescents, and young adults. Your doctor will monitor you closely for clinical worsening, suicidality, or unusual behavior after you start taking Zyprexa or a new dose. Tell your doctor right away if you experience anxiety, hostility, sleeplessness, restlessness, impulsive or dangerous behavior, or thoughts about suicide or dying; or if you have new symptoms or seem to be feeling worse.

If you have diabetes or are at risk for diabetes, monitor your blood sugar regularly, as determined by your doctor. Also, you can experience an increase in your blood cholesterol levels or weight gain while you are taking Zyprexa. Monitor your weight regularly.
Zyprexa can cause sudden decrease in your blood pressure with dizziness, rapid heartbeat, and faintness. Zyprexa can also cause seizures, problems with your body temperature regulation, difficulty swallowing, or impairment of your judgment, thinking, or motor skills.
