What Is Paliperidone XR?

Paliperidone XR is an extended-release atypical antipsychotic medication used to treat schizophrenia and schizoaffective disorder in adults and adolescents aged 12 and older.

Sold under the brand name Invega, Paliperidone XR is manufactured by Janssen Pharmaceuticals, a subsidiary of Johnson & Johnson. It was first approved by the FDA in 2006 and has since become a widely used treatment option for psychotic disorders.

Paliperidone is the primary active metabolite of Risperidone (Risperdal), another commonly prescribed antipsychotic. It belongs to the class of second-generation (atypical) antipsychotics and is not a controlled substance — it's available by prescription only.

What Is Paliperidone XR Used For?

Paliperidone XR is FDA-approved for two conditions:

Schizophrenia

Schizophrenia is a chronic mental health condition that affects how a person thinks, feels, and perceives reality. Symptoms can include hallucinations, delusions, disorganized thinking, and reduced emotional expression. Paliperidone XR helps manage these symptoms and is approved for both adults and adolescents aged 12 and older.

Schizoaffective Disorder

Schizoaffective disorder combines symptoms of schizophrenia (like hallucinations or delusions) with mood disorder symptoms (like depression or mania). Paliperidone XR can be used as monotherapy or alongside mood stabilizers and antidepressants.

Off-Label Uses

Some doctors prescribe Paliperidone XR off-label for conditions such as bipolar disorder (particularly manic episodes), treatment-resistant psychosis, irritability associated with autism spectrum disorder, and psychotic features in major depressive disorder. Off-label use means the FDA hasn't specifically approved the drug for that condition, but your doctor may determine it's appropriate based on clinical evidence.

How Is Paliperidone XR Taken?

Paliperidone XR comes as an extended-release oral tablet in four strengths:

• 1.5 mg
• 3 mg
• 6 mg
• 9 mg

Key instructions for taking Paliperidone XR:

• Take it once daily in the morning
• Swallow the tablet whole — do not crush, split, or chew it. The extended-release system requires the tablet to pass through your digestive system intact.
• Take it with or without food, but be consistent. Food increases absorption.
• The tablet shell may appear in your stool — this is normal and doesn't mean the medication didn't work. The drug has already been absorbed; what you're seeing is the empty outer shell.
• Take it at the same time every day for the best results.

The recommended starting dose is 6 mg once daily. Your doctor may adjust your dose between 3 mg and 12 mg per day based on how you respond and how well you tolerate the medication.

Other Formulations

In addition to the oral extended-release tablets, Paliperidone is also available as long-acting injectable formulations:

• Invega Sustenna — A monthly injection (paliperidone palmitate)
• Invega Trinza — An injection given every 3 months
• Invega Hafyera — An injection given every 6 months

These injectable forms are options for patients who prefer less frequent dosing or have difficulty remembering to take a daily pill.

Who Should Not Take Paliperidone XR?

Paliperidone XR is not appropriate for everyone. You should not take it if you have:

• A known allergy to Paliperidone, Risperidone, or any of the tablet's inactive ingredients
• Severe gastrointestinal narrowing — Because the tablet is non-deformable (it doesn't change shape), it could cause a blockage in patients with severe narrowing of the stomach or intestines

Additionally, Paliperidone XR carries an FDA boxed warning about increased mortality risk in elderly patients with dementia-related psychosis. It is not approved for treating behavioral symptoms of dementia.

Use with caution if you have:

• Kidney problems (dose adjustment required for moderate impairment; not recommended for severe)
• Heart disease or risk factors for QT prolongation
• History of seizures
• Conditions that make you prone to low blood pressure

If you're pregnant or planning to become pregnant, talk to your doctor. Taking Paliperidone XR in the third trimester may cause movement or withdrawal symptoms in newborns.

How Much Does Paliperidone XR Cost?

Cost is a significant concern for many patients. Here's what you can expect to pay in 2026:

• Brand-name Invega: $600 to $1,800+ per month, depending on dose and pharmacy
• Generic Paliperidone ER: As low as $36 per month with a discount coupon (such as from GoodRx)

Most insurance plans cover generic Paliperidone ER, though many require prior authorization or step therapy (meaning your insurance wants you to try a different antipsychotic like Risperidone first).

The Janssen CarePath Savings Program may cover brand Invega for eligible commercially insured patients, and the Johnson & Johnson Patient Assistance Foundation provides free medication to qualifying uninsured patients.
