Olanzapine is an antipsychotic medication that is used to treat psychotic conditions such as schizophrenia and bipolar disorder (manic depression) in adults and children at least 13 years old.

Olanzapine is also used together with fluoxetine (Prozac) to treat episodes of depression in adults and children at least 10 years old who have bipolar I disorder.

Olanzapine may also be used for purposes not listed in this medication guide.

Olanzapine is not approved for use in older adults with dementia-related psychosis.

Olanzapine comes as a tablet and an orally disintegrating tablet (tablet that dissolves quickly in the mouth) to take by mouth. It is usually taken once a day with or without food. Take olanzapine at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take olanzapine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Do not try to push the orally disintegrating tablet through the foil. Instead, use dry hands to peel back the foil packaging. Immediately take out the tablet and place it in your mouth. The tablet will quickly dissolve and can be swallowed with or without liquid.

Your doctor may start you on a low dose of olanzapine and gradually increase your dose.

Olanzapine may help control your symptoms, but it will not cure your condition. It may take several weeks or longer before you feel the full benefit of olanzapine. Continue to take olanzapine even if you feel well. Do not stop taking olanzapine without talking to your doctor. Your doctor will probably want to decrease your dose gradually.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Olanzapine can be taken with or without food.

Remove an orally disintegrating tablet (Zyprexa Zydis) from the package only when you are ready to take the medicine. Place the tablet in your mouth and allow it to dissolve, without chewing. Swallow several times as the tablet dissolves.

Olanzapine can cause high blood sugar (hyperglycemia). If you are diabetic, check your blood sugar levels on a regular basis.

You may gain weight or have high cholesterol and triglycerides (types of fat) while taking olanzapine, especially if you are a teenager. You may need frequent blood tests.

Call your doctor if your symptoms do not improve, or if they get worse while using olanzapine.

Do not stop using olanzapine suddenly, even if you feel fine. Stopping suddenly may cause serious side effects.

Olanzapine is sometimes used together with other antipsychotic medications or antidepressants. Use all medications as directed and read all medication guides you receive. Do not change your dose or dosing schedule without your doctor's advice.

Medication may be only part of a complete program of treatment that also includes counseling and other psychological support programs. Follow your doctor's instructions.

Store at room temperature away from moisture, heat, and light.

You should not take olanzapine if you are allergic to it.

Olanzapine may increase the risk of death in older adults with dementia-related psychosis and is not approved for this use.

Tell your doctor if you have ever had:

• liver disease;

• heart disease, high or low blood pressure;

• a stroke, including "mini-stroke";

• breast cancer;

• a seizure;

Taking antipsychotic medicine in the last 3 months of pregnancy may cause breathing problems, feeding problems, or withdrawal symptoms in the newborn. If you get pregnant, tell your doctor right away. Do not stop taking olanzapine without your doctor's advice.

Olanzapine can pass into breast milk. If you are breastfeeding, tell your doctor if you notice severe drowsiness, irritability, feeding problems, tremors, or unusual muscle movements in the nursing baby.

The olanzapine orally disintegrating tablet (Zyprexa Zydis) may contain phenylalanine. Tell your doctor if you have phenylketonuria (PKU).

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose symptoms may include drowsiness, agitation, aggression, slurred speech, confusion, increased heart rate, jerky or uncontrolled muscle movements, trouble breathing, or fainting.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Always store the orally disintegrating tablets in their sealed package, and use them immediately after opening the package.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Other drugs may affect olanzapine, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
