Zyprexa (Olanzapine)

Zyprexa is used to treat the symptoms of psychotic conditions such as schizophrenia and bipolar disorder (manic depression).

Zyprexa is an antipsychotic medication. It works by changing the actions of chemicals in the brain.

Do not use Zyprexa if:

• you are allergic to any ingredient in Zyprexa.

• if you are pregnant, planning to become pregnant, or are breast-feeding
• if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
• if you have allergies to medicines, foods, or other substances
• if you have a history of seizures, heart problems (eg, heart failure; fast, slow, or irregular heartbeat), abnormal electrocardiogram (ECG), heart attack, stroke, blood vessel problems, high blood cholesterol levels, or high or low blood pressure
• if you have a history of liver problems, stomach or bowel problems (eg, decreased muscle movement), enlarged prostate, narrow-angle glaucoma, neuroleptic malignant syndrome (NMS), aspiration pneumonia, or suicidal thoughts or attempts
• if you have Alzheimer disease, dementia, or trouble swallowing
• if you have diabetes or are very overweight, or if a family member has had diabetes
• if you have had high blood prolactin levels or a history of certain types of cancer (eg, breast, pancreas, pituitary), or if you are at risk for breast cancer
• if you are dehydrated, drink alcohol, or smoke, or you will be exposed to high temperatures

• Alpha blockers (eg, doxazosin), diazepam, or medicine for high blood pressure because the risk of low blood pressure and fainting may be increased
• Anticholinergics (eg, scopolamine), fluvoxamine, or lorazepam because they may increase the risk of Zyprexa 's side effects
• Carbamazepine, HIV protease inhibitors (eg, ritonavir), omeprazole, or rifampin because they may decrease Zyprexa 's effectiveness
• Dopamine receptor agonists (eg, pramipexole) or levodopa because their effectiveness may be decreased by Zyprexa

Check with your doctor if any of these most common side effects persist or become bothersome:

• back or joint pain; constipation; cough; dizziness; drowsiness; dry mouth; increased appetite; indigestion; lightheadedness; numbness or tingling of the skin; restlessness; sore throat; weakness; weight gain.

• severe allergic reactions (rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue); abnormal thoughts; chest pain; confusion; decreased urination; fainting; fast, slow, or irregular heartbeat; fever; increased saliva production or drooling; increased sweating; memory loss; menstrual changes; muscle pain, weakness, or stiffness; new or worsening mental or mood changes (eg, depression, hallucinations); seizures; severe or prolonged dizziness or headache; shortness of breath; swelling of the hands, legs, or feet; symptoms of high blood sugar (eg, increased thirst, hunger, urination; unusual weakness); tremor; trouble concentrating, speaking, or swallowing; trouble sitting still; trouble walking or standing; uncontrolled muscle movements (eg, arm or leg movements, twitching of the face or tongue, jerking or twisting); unusual bruising; vision changes; yellowing of the eyes or skin.

Zyprexa is to be used only by the patient for whom it is prescribed. Do not share it with other people.
If your symptoms do not improve or if they become worse, check with your doctor.
