  • Hypersensitivity.

Use Cautiously in:

  • Dehydration, use of antihypertensives, cardiovascular disease, or cerebrovascular disease (↑ risk of orthostatic hypotension and/or syncope);

  • Lactation:  Use while breastfeeding only if potential maternal benefit outweighs potential risk to infant;
  • Pedi:  Safety and effectiveness not established in children;
  • Black Box:   Geri:  Appears on Beers list. ↑ risk of stroke, cognitive decline, and mortality in older adults with dementia. Avoid use in older adults, except for schizophrenia or bipolar disorder..

Assessment

  • Assess mental status (orientation, mood, behavior) before and periodically during therapy.
  • Assess for suicidal tendencies, especially during early therapy. Restrict amount of drug available to patient. Risk may be ↑ in children, adolescents, and adults ≤24 yr. After starting therapy, young adults should be seen by health care provider face-to-face at least weekly for 4 wk, then every other wk for next 4 wk, then at 12 wk, and then on advice of health care provider thereafter.
  • Assess weight and BMI initially and periodically during therapy. Refer as appropriate for nutritional/weight management and medical management.
  • Observe patient carefully when administering medication to ensure that medication is actually taken and not hoarded or cheeked.
  • Lumateperone ↓ the seizure threshold. Institute seizure precautions for patients with history of seizure disorder.
  • Monitor patient for onset of extrapyramidal side effects ( akathisia: restlessness dystonia: muscle spasms and twisting motions; or  pseudoparkinsonism: masklike face, rigidity, tremors, drooling, shuffling gait, dysphagia). Report these symptoms; ↓ of dose or discontinuation of medication may be necessary.
  • Monitor for possible tardive dyskinesia (uncontrolled rhythmic movement of mouth, face, and extremities; lip smacking or puckering; puffing of cheeks; uncontrolled chewing; rapid or worm-like movements of tongue). Report these symptoms immediately; may be irreversible.
  • Monitor for development of neuroleptic malignant syndrome (fever, muscle rigidity, altered mental status, respiratory distress, tachycardia, seizures, diaphoresis, hypertension or hypotension, pallor, tiredness, loss of bladder control). Notify health care provider immediately if these symptoms occur.
  • Assess for falls risk. Drowsiness, orthostatic hypotension, and motor and sensory instability ↑ risk. Institute prevention if indicated.

Lab Test Considerations:

Monitor patients with clinically significant neutropenia for fever or other symptoms or signs of infection and treat promptly if such symptoms or signs occur. Discontinue lumateperone in patients with ANC <1000 cells/mm3  and follow WBC until recovery.

  • Assess fasting blood glucose and cholesterol levels before starting and periodically during therapy.
  • Monitor liver function tests periodically during therapy or if clinical signs of hepatotoxicity occur.

Implementation

  • PO Administer once daily with or without food.

Patient/Family Teaching

  • Instruct patient to take medication as directed.
  • Inform patient of possibility of extrapyramidal symptoms and tardive dyskinesia. Instruct patient to report these symptoms immediately.
  • Instruct patient to avoid grapefruit juice during therapy.
  • Advise patient to change positions slowly to minimize orthostatic hypotension. Protect from falls.
  • Inform patient that lumateperone may cause weight gain. Advise patient to monitor weight periodically. Notify health care provider of significant weight gain.
  • May cause seizures and drowsiness. Caution patient to avoid driving or other activities requiring alertness until response to drug is known.
  • Advise patient to avoid extremes in temperature and dehydration; this drug impairs body temperature regulation.
  • Instruct patient to notify health care provider of all Rx or OTC medications, vitamins, or herbal products being taken and to consult health care provider before taking any other medications, especially St. John's wort. Caution patient to avoid concurrent use of alcohol and other CNS depressants.
  • Instruct patient to use frequent mouth rinses, good oral hygiene, and sugarless gum or candy to minimize dry mouth.
  • Advise patient to notify health care provider of medication regimen before treatment or surgery.
  • Advise patient, family, and caregivers to watch for suicidality, especially during early therapy or dose changes. Notify health care provider immediately if thoughts about suicide or dying, attempts to commit suicide, new or worse depression or anxiety, agitation or restlessness, panic attacks, insomnia, new or worse irritability, aggressiveness, acting on dangerous impulses, mania, or other changes in mood or behavior occur.
  • Instruct patient to notify health care provider immediately if signs and symptoms of neuroleptic malignant syndrome occur unexplained fatigue, dyspnea, tachypnea, chest pain, palpitations, sore throat, fever, lethargy, weakness, malaise, or flu-like symptoms occur.
  • Rep:  Advise women of reproductive potential to notify health care provider if pregnancy is planned or suspected and to avoid breastfeeding. Encourage women who become pregnant while taking lumateperone to enroll in the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregi.... Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. May temporarily cause infertility in men and women.

Evaluation/Desired Outcomes

  • Decrease in positive symptoms (delusions, hallucinations) of schizophrenia.
  • Decrease in negative symptoms (social withdrawal, flat, blunted affect) of schizophrenia.
  • Decreased symptoms of depression associated with bipolar disorder.
