FDA boxed warningIncreased mortality in elderly patients with dementia-related psychosis
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. INVEGA TRINZA is not approved for use in patients with dementia-related psychosis.
About Invega Trinza
Overview
Invega Trinza is an extended-release antipsychotic injection containing paliperidone palmitate, which the body converts to paliperidone. It treats schizophrenia in patients who have already been adequately treated with Invega Sustenna. Its exact mechanism is unclear, but it may work by blocking certain dopamine and serotonin receptors in the brain.
What it treats
Schizophrenia in patients who have been adequately treated with Invega Sustenna for at least four months.
Safety information
Side effects
Common side effects of Invega Trinza include reactions at the injection site, weight gain, headache, upper respiratory tract infection, restlessness (akathisia), and Parkinson-like movement problems (parkinsonism). Serious side effects that need urgent medical attention include neuroleptic malignant syndrome, changes in the heart’s electrical rhythm (QT prolongation), seizures, and a prolonged erection (priapism). In older adults with dementia-related psychosis, there is an increased risk of stroke, including fatal stroke, and death. Invega Trinza is not approved for use in people with dementia-related psychosis. Contact a doctor promptly about uncontrolled movements (tardive dyskinesia), fainting or low blood pressure when standing, falls, difficulty swallowing, or problems regulating body temperature. Other important risks include reduced white blood cell counts, increased prolactin levels, high blood sugar or diabetes, changes in blood fats, and significant weight gain. Symptoms of high blood sugar can include increased thirst, frequent urination, increased hunger, and weakness. Your doctor may monitor weight and blood sugar. Blood count monitoring is recommended if you have a history of significantly low white blood cell counts or medicine-related reductions in these cells. Invega Trinza can also impair thinking and movement; use caution when operating machinery.
FDA boxed warning
Increased mortality in elderly patients with dementia-related psychosis
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. INVEGA TRINZA is not approved for use in patients with dementia-related psychosis.
A boxed warning is the strongest warning the US Food and Drug Administration requires on a medicine label. Text is taken from the official label, with internal section references removed.
When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
Do not use Invega Trinza if you are allergic to paliperidone, risperidone or any of its other ingredients. Severe allergic reactions, including anaphylaxis and swelling beneath the skin (angioedema), have been reported. Invega Trinza is not approved for dementia-related psychosis. The label warns of an increased risk of stroke and similar events, including fatal events, in older people with this condition. Avoid use with medicines that prolong the QT interval (a change in the heart’s electrical rhythm), or if you have risk factors for QT prolongation. Tell your prescriber if you have heart or blood vessel disease, a tendency towards low blood pressure or fainting, seizures, or conditions that increase seizure risk. Caution and monitoring are needed if you have diabetes or risk factors for diabetes, or a history of significantly low white blood cell counts or medicine-related reductions in these cells. Treatment may increase blood sugar, blood fats, weight and prolactin levels. Other serious risks include neuroleptic malignant syndrome and tardive dyskinesia, an involuntary movement disorder. Neuroleptic malignant syndrome requires immediate discontinuation and close medical monitoring; tardive dyskinesia may require treatment to be stopped by your prescriber. Use caution when operating machinery because treatment may impair thinking and movement. Tell your prescriber if you are pregnant. Exposure during the third trimester may cause movement-related or withdrawal symptoms in the newborn.
Interactions
Tell your doctor if you take carbamazepine, rifampin or St John’s wort. These medicines and supplements, along with other strong inducers of CYP3A4 or P-glycoprotein, should be avoided during an Invega Trinza treatment interval. If one is necessary, your doctor may need to change your treatment.
Using Invega Trinza
Dosing
