What is Caplyta?

Caplyta is used to treat adults with schizophrenia, depression associated with bipolar I or bipolar II disorder (manic depression), or along with antidepressant medicines to treat major depressive disorder (MDD). Caplyta is a once-daily capsule. When used to treat bipolar disorder, this medicine can be used alone or with lithium or valproic acid.

Clinical trials have reported improvement in the positive and negative symptoms of schizophrenia within one week of starting Caplyta (lumateperone), but symptoms may take longer to resolve when used for depression .

Important Information

Caplyta carries a Boxed Warning for increased risk of death in elderly patients with dementia-related psychosis and an increased risk of suicidal thoughts and behaviors in younger patients.

  • Increased risk of death in elderly people with dementia related psychosis. Medicines like Caplyta can raise the risk of death in elderly people who have lost touch with reality (psychosis) due to confusion and memory loss (dementia). Caplyta is not approved for the treatment of people with dementia-related psychosis.
  • Increased risk of suicidal thoughts and actions. Caplyta and antidepressant medicines increase the risk of suicidal thoughts and actions in people 24 years of age and younger, especially within the first few months of treatment or when the dose is changed.
    • Depression and other mental illnesses are the most important causes of suicidal thoughts and actions.

How can I watch for and try to prevent suicidal thoughts and actions in myself or a family member?

    • Pay close attention to any changes, especially sudden changes in mood, behaviors, thoughts, or feelings. This is very important when Caplyta or the antidepressant medicine is started or when the dose is changed.
    • Call your healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings, or if you develop suicidal thoughts or actions.
    • Keep all follow-up visits with your healthcare provider as scheduled. Call your healthcare provider between visits as needed, especially if you have concerns about symptoms.

Call a healthcare provider right away if you or your family member has any of the following symptoms, especially if they are new, worse, or worry you:

    • Thoughts about suicide or dying
    • New or worse depression
    • Feeling very agitated or restless
    • Trouble sleeping
    • Acting aggressively, being angry, or violent
    • An extreme increase in activity and talking (mania)
    • Suicide attempts
    • New or worse anxiety
    • Panic attacks
    • New or worse irritability
    • Acting on dangerous impulses
    • Other unusual changes in behavior or mood.

  • Diarrhea.

Caplyta may cause fertility problems in females and males. Talk to your healthcare provider if this is a concern for you.

Caplyta does not appear to be associated with weight gain like many other antipsychotics are.

Serious Side Effects

Caplyta can also cause the following other serious side effects:

  • Stroke (cerebrovascular problems) in elderly people with dementia-related psychosis, which can lead to death. Caplyta is not approved for the treatment of people with dementia-related psychosis.
  • Neuroleptic malignant syndrome (NMS) a serious condition that can lead to death. Call your healthcare provider or go to the nearest hospital emergency room right away if you have some or all of the following signs and symptoms of NMS:
    • High fever
    • Confusion
    • Changes in your breathing, heart rate, and blood pressure
    • Stiff muscles
    • Increased sweating.
  • Uncontrolled body movements (tardive dyskinesia). Caplyta may cause movements that you cannot control in your face, tongue, or other body parts. Tardive dyskinesia may not go away, even if you stop taking Caplyta. Tardive dyskinesia may also start after you stop taking Caplyta.
  • Problems with your metabolism, such as:
    • High blood sugar (hyperglycemia) and diabetes. Increases in blood sugar can happen in some people who take Caplyta. Extremely high blood sugar can lead to coma or death. Your healthcare provider should check your blood sugar before you start, or soon after you start Caplyta, and then regularly during long-term treatment with Caplyta.

Call your healthcare provider if you have any of these symptoms of high blood sugar during treatment with Caplyta:

      • Feel very thirsty
      • Need to urinate more than usual
      • Feel very hungry
      • Feel weak or tired
      • Feel sick to your stomach
      • Feel confused, or your breath smells fruity.
    • Increased fat levels (cholesterol and triglycerides) in your blood. Your healthcare provider should check the fat levels in your blood before you start, or soon after you start Caplyta, and then periodically during treatment with Caplyta.
    • Weight gain. Weight gain is uncommon, but you and your healthcare provider should check your weight before you start and regularly during treatment with Caplyta.
  • Low white blood cell counts. Your healthcare provider may do blood tests during the first few months of treatment with Caplyta.
  • Decreased blood pressure (orthostatic hypotension). You may feel lightheaded or faint when you rise too quickly from a sitting or lying position after taking Caplyta.
  • Falls. Caplyta may make you sleepy or dizzy, may cause a decrease in your blood pressure when changing position (orthostatic hypotension), and can slow your thinking and motor skills, which may lead to falls that can cause fractures or other injuries.
  • Seizures (convulsions). Caplyta may increase your risk of seizures.
  • Sleepiness, drowsiness, feeling tired, difficulty thinking, and doing normal activities.
  • Difficulty swallowing, which can cause food or liquid to get into your lungs. Tell your healthcare provider immediately if this happens.
  • Problems controlling your body temperature so that you feel too warm.

This is not a complete list of Caplyta side effects, and others may occur. Call your doctor for medical advice about side effects.

How Does Caplyta Work?

Caplyta works by changing the activity of neurotransmitters in the brain, such as dopamine, glutamate, and serotonin, to increase or balance their levels. This helps to relieve symptoms such as hallucinations, delusions, and disorganized thoughts associated with schizophrenia, and low mood associated with depression. 

Caplyta belongs to the drug class called atypical antipsychotics.
