Nursing implications

Nursing assessment

  • Monitor patient’s mental status (orientation, mood, behavior) before and periodically during therapy. Monitor closely for notable changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression, especially during early therapy. Restrict amount of drug available to patient.
  • Assess weight and BMI initially and throughout therapy.
  • Monitor BP (sitting, standing, lying down) and pulse before and periodically during therapy. May cause prolonged QT interval, tachycardia, and orthostatic hypotension.
  • Observe patient when administering medication to ensure that medication is actually swallowed and not hoarded or cheeked.
  • Monitor patient for onset of extrapyramidal side effects (akathisia—restlessness; dystonia—muscle spasms and twisting motions; or pseudoparkinsonism—mask-like face, rigidity, tremors, drooling, shuffling gait, dysphagia). Report these symptoms; reduction of dose or discontinuation of medication may be necessary.
  • Monitor for tardive dyskinesia (involuntary rhythmic movement of mouth, face, and extremities). Report immediately; may be irreversible.
  • Monitor for development of neuroleptic malignant syndrome (fever, respiratory distress, tachycardia, seizures, diaphoresis, hypertension or hypotension, pallor, tiredness). Discontinue paliperidone and notify health care professional immediately if these symptoms occur.
  • Monitor for symptoms related to hyperprolactinemia (menstrual abnormalities, galactorrhea, sexual dysfunction).
  • Lab Test Considerations: Monitor fasting blood glucose and cholesterol levels before and periodically during therapy.
    • Monitor serum prolactin prior to and periodically during therapy. May cause ↑ serum prolactin levels.
    • Monitor CBC frequently during initial months of therapy in patients with pre-existing or history of low WBC. May cause leukopenia, neutropenia, or agranulocytosis. Discontinue therapy if this occurs.

Implementation

  • Oral: Administer once daily in the morning without regard to food. Tablets should be swallowed whole; do not crush, break or chew.
  • Intramuscular: Administer initial and second doses in deltoid using a 1 1/2-inch, 22 gauge needle for patients ≥90 kg (≥200 lb) or 1-inch 23 gauge needle for patients <90 kg (<200 lb). Monthly maintenance doses can be administered in either deltoid or gluteal sites. For gluteal injection, use 1 1/2-inch, 22 gauge needle regardless of patient weight. To avoid missed dose, may give second dose 4 days before or after the 1-wk timepoint. Monthly doses may be given up to 7 days before or after the monthly timepoint. After 1st month, if missed dose is within 4 wk of scheduled dose, administer 2nd dose of 156 mg as soon as possible. Give 3rd dose of 117 mg in either deltoid or gluteal muscle 5 wk after first injection (regardless of timing of 2nd injection). Then return to normal monthly injections in either deltoid or gluteal muscle. If >4 wk and <7 wk since 1st injection, resume by administering 156 mg dose in deltoid as soon as possible, a second 156 mg dose in deltoid in 1 wk, followed by monthly doses in deltoid or gluteal sites. If > 7 months since scheduled dose, administer using initial dosing schedule. During regular monthly dose schedule, if <6 wks since last injection, administer previously stabilized dose as soon as possible, then monthly. If >6 wks since last injection, resume dose previously stabilized on, unless stabilized on 234 mg (then 1st two injections should be 156 mg). Administer 1 dose in deltoid as soon as possible, then another deltoid injection of same dose 1 wk later, then resume regular monthly schedule. If >6 months since last injection, administer using initial dosing schedule.

Patient/Family Teaching

  • Instruct patient to take medication as directed. Advise patient that appearance of tablets in stool is normal and not of concern.
  • Inform patient of the possibility of extrapyramidal symptoms. Instruct patient to report these symptoms immediately to health care professional.
  • Advise patient to change positions slowly to minimize orthostatic hypotension.
  • May cause drowsiness. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.
  • Advise patient and family to notify health care professional if thoughts about suicide or dying, attempts to commit suicide; new or worse depression; new or worse anxiety; feeling very agitated or restless; panic attacks; trouble sleeping; new or worse irritability; acting aggressive; being angry or violent; acting on dangerous impulses; an extreme increase in activity and talking, other unusual changes in behavior or mood occur.
  • Advise patient that extremes in temperature should also be avoided; this drug impairs body temperature regulation.
  • Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications and alcohol.
  • Advise patient to seek nutritional, weight, or medical management as needed for weight gain or cholesterol elevation.
  • Instruct patient to notify health care professional promptly if sore throat, fever, unusual bleeding or bruising, rash, tremors, menstrual abnormalities, galactorrhea, or sexual dysfunction occur.
  • Advise patient to notify health care professional of medication regimen before treatment or surgery.
  • Advise female patients to notify health care professional if pregnancy is planned or suspected, or if breast feeding or planning to breast feed.
  • Emphasize the importance of routine follow-up exams to monitor side effects and continued participation in psychotherapy to improve coping skills.

Evaluation/Desired Outcomes

  • Decrease in excited, manic behavior.
  • Decrease in positive symptoms (delusions, hallucinations) of schizophrenia.
  • Decrease in negative symptoms (social withdrawal, flat, blunted affect) of schizophrenia.
