Lumateperone

Studies have shown that older adults with dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and that may cause changes in mood and personality) who take antipsychotics (medications for mental illness) such as lumateperone have an increased chance of death during treatment. Older adults with dementia may also have a greater chance of having a stroke or mini-stroke during treatment.

Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests to check your body's response to lumateperone.

Lumateperone is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Lumateperone is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.

Lumateperone comes as a capsule to take by mouth. It is usually taken with food once daily. Take lumateperone 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 lumateperone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Lumateperone 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 lumateperone. Continue to take lumateperone even if you feel well. Do not stop taking lumateperone without talking to your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

• you should know that you may experience hyperglycemia (increases in your blood sugar) while you are taking this medication, even if you do not already have diabetes. If you have schizophrenia, you are more likely to develop diabetes than people who do not have schizophrenia, and taking lumateperone or similar medications may increase this risk. Tell your doctor immediately if you have any of the following symptoms while you are taking lumateperone: extreme thirst, frequent urination, extreme hunger, blurred vision, or weakness. It is very important to call your doctor as soon as you have any of these symptoms, because high blood sugar can cause a serious condition called ketoacidosis.

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).

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. https://www.upandaway.org

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.
