Paliperidone
Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Paliperidone is the active metabolite of risperidone and is used for schizophrenia and schizoaffective disorder. Oral extended-release dosing is strongly affected by renal function, and long-acting paliperidone palmitate injections are used for maintenance treatment. Like other antipsychotics, it carries a boxed warning for increased mortality in elderly patients with dementia-related psychosis.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Paliperidone is the active metabolite of risperidone and is used for schizophrenia and schizoaffective disorder. NutriStack rates the supporting evidence as strong. Common adult dosing is Oral extended-release: commonly 6 mg once daily in adults, with range 3-12 mg once daily adjusted for response and renal function. Long-acting injectable dosing depends on product, prior tolerability, and renal function., though a prescriber sets the actual dose. This profile indexes 3 sources.
The bottom line
Evidence rating strong. Most-documented uses: treatment of schizophrenia, treatment of schizoaffective disorder, maintenance therapy with long-acting injectable formulations. 3 sources indexed (2007–2025), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Paliperidone antagonizes dopamine D2 and serotonin 5-HT2A receptors, with additional alpha-adrenergic and histamine receptor activity. Antipsychotic effects are primarily related to dopamine-serotonin blockade. The drug is substantially renally eliminated, so kidney function has major dosing implications; it can also increase prolactin and modestly prolong QT interval in susceptible patients.2,3
Dosing & protocol.
Oral extended-release tablets may be taken with or without food but should be taken consistently the same way. Tablets must be swallowed whole.

What is Paliperidone?
Paliperidone is the active metabolite of risperidone and is used for schizophrenia and schizoaffective disorder. Oral extended-release dosing is strongly affected by renal function, and long-acting paliperidone palmitate injections are used for maintenance treatment. Like other antipsychotics, it carries a boxed warning for increased mortality in elderly patients with dementia-related psychosis.
What is Paliperidone used for?
Commonly cited benefits of Paliperidone include: Treatment of schizophrenia; Treatment of schizoaffective disorder; Maintenance therapy with long-acting injectable formulations; Relapse prevention in stabilized patients. NutriStack rates the overall evidence as strong.
What is a typical dose of Paliperidone?
A typical adult dose of Paliperidone is Oral extended-release: commonly 6 mg once daily in adults, with range 3-12 mg once daily adjusted for response and renal function. Long-acting injectable dosing depends on product, prior tolerability, and renal function.. The commonly recommended form is Oral extended-release tablet swallowed whole, or long-acting injectable paliperidone palmitate after oral tolerability is established. These are general ranges, not personalized advice; confirm the right dose with a clinician.
What are the side effects of Paliperidone?
Reported side effects include extrapyramidal symptoms, akathisia, somnolence, weight gain, hyperprolactinemia, orthostatic hypotension. This is educational information; check with a healthcare professional before use.
How strong is the evidence for Paliperidone?
NutriStack rates this as Strong, meaning multiple high-quality meta-analyses or systematic reviews converge on the same finding. Full tier criteria are at https://nutristackapp.com/methodology/evidence-tiers.
