INVEGA TRINZA® Common Dosing and Administration Topics


Incomplete Administration

Consistent with the INVEGA TRINZA® Prescribing Information:

  • Incomplete Administration - To avoid an incomplete administration of INVEGA TRINZA®, ensure that the prefilled syringe is shaken vigorously for at least 15 seconds within 5 minutes prior to administration to ensure a homogeneous suspension and ensure the needle does not get clogged during injection.
  • However, in the event of an incompletely administered dose, do not re-inject the dose remaining in the syringe and do not administer another dose of INVEGA TRINZA®. Closely monitor and treat the patient with oral supplementation as clinically appropriate until the next scheduled 3-month injection of INVEGA TRINZA®.

INVEGA TRINZA® (paliperidone palmitate)

The Educational Dose Illustrator can be used to visualize how dosing affects paliperidone plasma concentrations following administration of:


  • the treatment of schizophrenia in adults
  • the treatment of schizoaffective disorder in adults as monotherapy and as an adjunct to mood stabilizers or antidepressants


  • the treatment of schizophrenia in patients after they have been adequately treated with INVEGA SUSTENNA® for at least four months.

This resource simulates the paliperidone plasma concentrations over time resulting from different dosing scenarios that are set forth in the respective Prescribing Information for INVEGA SUSTENNA® and INVEGA TRINZA®. The Educational Dose Illustrator is intended to be used as a resource to foster a better understanding of, and educate healthcare professionals about, the dosing recommendations provided in the respective Prescribing Information for INVEGA SUSTENNA® and INVEGA TRINZA®. It is intended for educational purposes only.

Because the simulated patient paliperidone plasma levels shown in the dosing scenarios are based upon aggregated pharmacokinetic information from clinical studies, the simulations may not be representative of individual patient response.
