All FDA black box warnings are at the end of this fact sheet. Please review before taking this medication.
Lumateperone is a medication that works in the brain to treat schizophrenia. It is also known as a second generation antipsychotic (SGA) or atypical antipsychotic. Lumateperone rebalances dopamine, serotonin, and glutamate to improve thinking, mood, and behavior.
Symptoms of schizophrenia include:
Lumateperone may help some or all of these symptoms.
Lumateperone is also FDA approved for the treatment of depressive phases of bipolar disorder.
This medication sheet will focus primarily on schizophrenia. You can find more information about bipolar disorder here.
Lumateperone may also be helpful when prescribed “off-label” for other mental health conditions. “Off-label” means that it has not been approved by the Food and Drug Administration for this condition. Your mental health provider should justify his or her thinking in recommending an “off-label” treatment. They should be clear about the limits of the research around that medication and if there are any other options.
Schizophrenia requires long-term treatment. Do not stop taking lumateperone, even when you feel better.
With input from you, your health care provider will assess how long you will need to take the medication.
Missing doses of lumateperone may increase your risk for a relapse in your symptoms.
Do not stop taking lumateperone or change your dose without talking with your health care provider first.
For lumateperone to work properly, it should be taken every day as ordered by your health care provider.
If you are planning on becoming pregnant, notify your health care provider to best manage your medications. People living with schizophrenia who wish to become pregnant face important decisions. This is a complex decision since untreated schizophrenia has risks to the fetus, as well as the mother. It is important to discuss the risks and benefits of treatment with your doctor and caregivers.
Antipsychotic use during the third trimester of pregnancy has a risk for abnormal muscle movements (extrapyramidal symptoms [EPS]) and/or withdrawal symptoms in newborns following delivery. Symptoms in the newborn may include agitation, feeding disorder, hypertonia, hypotonia, respiratory distress, somnolence, and tremor; these effects may be self-limiting or require hospitalization.
Caution is advised with breastfeeding since it is not known if lumateperone passes into breast milk.
Lumateperone is usually taken 1 time per day with food. Do not take lumateperone with grapefruit juice.
For schizophrenia, the dose is 42 mg once daily.
Use a calendar, pillbox, alarm clock, or cell phone alert to help you remember to take your medication. You may also ask a family member or a friend to remind you or check in with you to be sure you are taking your medication.
If you miss a dose of lumateperone, take it as soon as you remember, unless it is closer to the time of your next dose. Discuss this with your health care provider. Do not double your next dose or take more than what is prescribed.
Avoid drinking alcohol or using illegal drugs while you are taking lumateperone. They may decrease the benefits (e.g., worsen your confusion) and increase adverse effects (e.g., sedation) of the medication.
If an overdose occurs call your doctor or 911. You may need urgent medical care. You may also contact the poison control center at 1-800-222-1222.
A specific treatment to reverse the effects of lumateperone does not exist.
Drowsiness/sedation, dry mouth
Some people may develop muscle related side effects while taking lumateperone. The technical terms for these are “extrapyramidal symptoms” (EPS) and “tardive dyskinesia” (TD). Symptoms of EPS include restlessness, tremor, and stiffness. TD symptoms include slow or jerky movements that one cannot control, often starting in the mouth with tongue rolling or chewing movements.
Temperature regulation: Impaired core body temperature regulation may occur; caution with strenuous exercise, heat exposure, and dehydration.
Second generation antipsychotics (SGAs) increase the risk of weight gain, high blood sugar, and high cholesterol. This is also known as metabolic syndrome. Your health care provider may ask you for a blood sample to check your cholesterol, blood sugar, and hemoglobin A1c (a measure of blood sugar over time) while you take this medication.
SGAs have been linked with higher risk of death, strokes, and transient ischemic attacks (TIAs) in elderly people with behavior problems due to dementia.
All antipsychotics have been associated with the risk of sudden cardiac death due to an arrhythmia (irregular heart beat). To minimize this risk, antipsychotic medications should be used in the smallest effective dose when the benefits outweigh the risks. Your doctor may order an EKG to monitor for irregular heartbeat.
Neuroleptic malignant syndrome is a rare, life threatening adverse effect of antipsychotics which occurs in <1% of patients. Symptoms include confusion, fever, extreme muscle stiffness, and sweating. If any of these symptoms occur, contact your health care provider immediately.
All antipsychotics can cause sedation, dizziness, or orthostatic hypotension (a drop in blood pressure when standing up from sitting or lying down). These side effects may lead to falls which could cause bone fractures or other injuries. This risk is higher for people with conditions or other medications that could worsen these effects. If falls or any of these symptoms occur, contact your health care provider.
Tardive dyskinesia (TD) is a side effect that develops with prolonged use of antipsychotics. Medications such as lumateperone have been shown to have a lower risk of TD compared to older antipsychotics, such as Haldol® (haloperidol). If you develop symptoms of TD, such as grimacing, sucking, and smacking of lips, or other movements that you cannot control, contact your health care provider immediately. All patients taking either first or second generation antipsychotics should have an Abnormal Involuntary Movement Scale (AIMS) completed regularly by their health care provider to monitor for TD.
Second generation antipsychotics (SGAs) increase the risk of diabetes, weight gain, high cholesterol, and high triglycerides. (See “Serious Side Effects” section for monitoring recommendations.)
The following medications may increase the levels and effects of lumateperone: diltiazem (Cardizem®), erythromycin (Ery-Tab®), fluconazole (Diflucan®), and valproic acid (Depakene®). Grapefruit juice may also increase levels of lumateperone.
The following medications may decrease the levels and effects of lumateperone: carbamazepine (Tegretol®) and phenobarbital.
It is very important to tell your doctor how you feel things are going during the first few weeks after you start taking lumateperone. It will probably take several weeks to see big enough changes in your symptoms to decide if lumateperone is the right medication for you.
Antipsychotic treatment is generally needed lifelong for persons with schizophrenia. Your doctor can best discuss the duration of treatment you need based on your symptoms and illness.
Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide.
