Caplyta (Lumateperone) - Oral


Caplyta should not be used in people with dementia-related psychosis (losing touch with reality due to confusion and memory loss). Older adults with dementia-related psychosis who take antipsychotic medications have a higher risk of death. Antidepressants have been shown to increase the risk of suicidal thoughts and behavior in children and young adults. People of any age who take Caplyta should be monitored for changes in mood and behavior. However, Caplyta is not approved for use in children or adolescents under age 18.

What Is Caplyta?

Caplyta (lumateperone) is an oral prescription drug used to treat schizophrenia or bipolar depression. It is available as a capsule that is taken by mouth.

Caplyta is in a drug class called atypical antipsychotics, or second-generation antipsychotics. Second-generation antipsychotics have fewer side effects than older or first-generation antipsychotics. The exact way Caplyta works is not entirely understood, but it is thought to act on dopamine and serotonin receptors in the brain.

What Is Caplyta Used For?

The Food and Drug Administration (FDA) approved Caplyta to treat adults with schizophrenia. Schizophrenia is a condition that affects a person's ability to behave, think, and feel clearly.

Caplyta can also be used to treat depressive episodes (the lows) related to bipolar I or II disorder in adults. This is called bipolar depression. For bipolar depression, Caplyta can be taken alone or in combination with other medications such as lithium or valproate.

How to Take Caplyta

Before starting your treatment with Caplyta, read your prescription label and the information leaflet that comes with your prescription. If you have any questions, don't hesitate to ask your healthcare provider. It's important to take this drug exactly as prescribed, usually once per day.

There are a few important things to keep in mind while using Caplyta:

  • It may cause you to feel drowsy. Make sure to avoid driving or using machinery until you know how you will feel after taking it. Alcohol can increase the drowsiness caused by Caplyta, so you may not want to drink alcohol while using this medication.
  • Be careful not to become too hot or dehydrated. Drink plenty of water and try to avoid spending long periods in the sun. If it's hot outside, wear lighter clothing to keep cool and avoid excessive exercise.
  • Grapefruit can interact with Caplyta. Do not drink grapefruit juice or eat grapefruit while on this medication.
  • Tell your healthcare provider if you become sick with diarrhea or are vomiting.


Store Caplyta at room temperature, away from heat, direct light, and moisture. Keep this medication in its original labeled container and out of the reach and sight of children and pets. Keep the bottle tightly closed when not in use.

Off-Label Uses

Healthcare providers may prescribe this medication for off-label uses, meaning for conditions not specifically indicated by the FDA. In some cases, Caplyta may be used for other mental health conditions.

How Long Does Caplyta Take To Work?

You may start to notice an improvement in symptoms within a week or two, but it may take up to two or three months to see the full effect of Caplyta. Antipsychotic medication is usually required as a lifelong treatment.

What Are the Side Effects of Caplyta?

This is not a complete list of side effects and others may occur. A healthcare provider can advise you on side effects. If you experience other effects, contact your healthcare provider. You may report side effects to the FDA at or 1-800-FDA-1088.

Like other medications, Caplyta can cause side effects. Tell your healthcare provider about any side effects you experience while taking this medication.

Common Side Effects

The most common side effects of Caplyta are:

  • Excess sleepiness/tiredness
  • Stomach problems such as stomach pain, nausea, vomiting, and diarrhea
  • Headache
  • High cholesterol
  • Dizziness
  • Dry mouth
  • Appetite loss
  • Upper respiratory infection
  • Impaired body temperature regulation (the body feels warm and has trouble cooling down)
  • Increased levels of liver enzymes
  • Increased levels of creatinine phosphokinase, which can indicate a life-threatening condition called neuroleptic malignant syndrome (NMS)

Severe Side Effects

Call your healthcare provider right away if you have serious side effects. Call 911 if your symptoms feel life-threatening or if you think you’re having a medical emergency. Serious side effects and their symptoms can include the following:

  • Hypersensitivity reaction or anaphylaxis: Symptoms can include rash, hives, swelling around the lips, tongue, and face, difficulty breathing, and require emergency medical attention. 
  • Suicidal thoughts and behavior: Call your healthcare provider immediately if you have mood and behavior changes. Your friends, family, and/or caregivers can also monitor you for changes in mood and behavior, such as depression, anxiety, agitation, irritability, panic attack, or thoughts about suicide.
  • Stroke or mini-stroke: Get emergency medical help if you have symptoms of face drooping or numbness, especially on one side; trouble with speech; or arm weakness or numbness.
  • Fainting: Notify your healthcare provider if fainting occurs during treatment with Caplyta.
  • Orthostatic hypotension: This is a drop in blood pressure when you stand up from a sitting or lying down position. Stand up slowly, and hold onto something sturdy for support. Notify your healthcare provider if you feel lightheaded or dizzy.
  • Neuroleptic malignant syndrome: Also known as NMS, this condition can be fatal, so it requires emergency medical attention. Symptoms may include high fever, irregular pulse, fast heartbeat, sweating, stiff muscles, and anxiety.
  • Muscle-related side effects, including extrapyramidal symptoms (restlessness, tremor, stiffness) and tardive dyskinesia (repetitive, involuntary movements such as eye blinking, grimacing, and lip-smacking) may occur. Report these side effects to your healthcare provider.
  • Dystonia: Symptoms include neck spasms and can progress to throat tightness and difficulty swallowing and/or breathing. Get medical help right away if this occurs.
  • Hyperglycemia (high blood sugar) or diabetes mellitus: Symptoms may include increased thirst and urination, dry mouth, and breath that smells like fruit. Notify your healthcare provider if symptoms occur.
  • Decreased blood cell counts: This can increase the risk of infection and can be life-threatening or cause death in some cases. Your healthcare provider will monitor blood cell counts.
  • Seizures: Caplyta can cause seizures. The risk is higher in people who have a history of seizures.
  • Hyperthermia: Caplyta can cause you to become overheated. Drink plenty of fluids while taking Caplyta and avoid staying out in the sun. If it is hot outside, stay inside as much as possible. Avoid wearing heavy clothes. Discuss exercise options with your healthcare provider, ensuring that you do not exercise excessively, especially in the heat.

Long-Term Side Effects

Long-term or delayed side effects are possible with Caplyta treatment.

Tardive dyskinesia (TD) is a common side effect that occurs when antipsychotics are taken for a long time. Although TD is less likely to occur with new antipsychotics, it is possible.

Symptoms of TD can include:

  • Eye blinking
  • Grimacing
  • Sucking and smacking of the lips

Your healthcare provider will have you regularly complete an Abnormal Involuntary Movement Scale (AIMS).

Second-generation antipsychotics, including Caplyta, can also increase the risk of high blood sugar (and diabetes), weight gain, and high cholesterol. Your healthcare provider will monitor you for these complications.

Report Side Effects

Caplyta may cause other side effects. Call your healthcare provider if you have any unusual problems while taking this medication.

If you experience a serious side effect, you or your healthcare provider may send a report to the FDA's MedWatch Adverse Event Reporting Program or by phone (800-332-1088).
