Having trouble finding Paliperidone XR at your pharmacy? Learn why this antipsychotic medication is hard to find in 2026 and what you can do about it.
If you've been told your pharmacy is out of Paliperidone XR — or that it's on backorder — you're not alone. Patients across the country have been struggling to fill their prescriptions for this important antipsychotic medication. For people managing schizophrenia or schizoaffective disorder, a gap in medication can be more than inconvenient — it can be dangerous.
In this article, we'll explain what Paliperidone XR is, why it's been difficult to find, and what steps you can take to get your medication filled.
Paliperidone XR (brand name Invega) is an extended-release oral tablet used to treat schizophrenia and schizoaffective disorder in adults and adolescents aged 12 and older. It belongs to a class of medications called atypical antipsychotics (also known as second-generation antipsychotics).
Paliperidone works by blocking dopamine D2 and serotonin 5-HT2A receptors in the brain, which helps reduce symptoms like hallucinations, delusions, and disorganized thinking. It's the active metabolite of Risperidone, another widely used antipsychotic.
The medication comes in extended-release tablets at strengths of 1.5 mg, 3 mg, 6 mg, and 9 mg. You take it once a day, swallowing the tablet whole — it should never be crushed, split, or chewed. For a deeper dive into how this medication works, see our guide on how Paliperidone XR works.
There are several reasons why you might have trouble filling your Paliperidone XR prescription right now:
While generic Paliperidone ER is available, only a handful of manufacturers produce it. When even one manufacturer experiences a production delay or quality issue, the supply chain can tighten quickly. Unlike medications with dozens of generic makers, specialty psychiatric drugs often have fewer suppliers.
The pharmaceutical supply chain has faced ongoing challenges in recent years. Raw material shortages, shipping delays, and manufacturing quality issues can all contribute to sporadic availability. These disruptions don't always make the FDA's official shortage list but can still leave pharmacy shelves empty in certain regions.
Some pharmacies — especially large chains — stock medications based on anticipated demand and insurance contracts. If your pharmacy's wholesaler doesn't carry a particular generic manufacturer's version, or if your insurance requires a specific NDC (National Drug Code), your pharmacist may have trouble sourcing it even when the drug is technically available elsewhere.
As awareness of schizoaffective disorder has grown and more patients are being treated, demand for medications like Paliperidone XR has increased. When demand outpaces supply — even slightly — patients at the end of the distribution chain may face delays.

Running out of an antipsychotic medication is stressful, but there are practical steps you can take:
Independent pharmacies often have access to different wholesalers than large chains like CVS or Walgreens. They may be able to source your medication when bigger stores can't. Specialty pharmacies that focus on psychiatric or mental health medications can also be a good option.

Instead of calling pharmacy after pharmacy, you can check availability online and save yourself time and frustration.

If you absolutely cannot find Paliperidone XR, talk to your prescriber about temporary alternatives. Medications like Risperidone, Aripiprazole (Abilify), Quetiapine XR (Seroquel XR), or Olanzapine (Zyprexa) may be appropriate substitutes depending on your situation.

It's important to never stop taking Paliperidone XR without talking to your doctor first. Abruptly stopping antipsychotic medication can lead to withdrawal symptoms or a relapse of your condition. If you're running low, contact your prescriber right away to discuss your options.
Finding Paliperidone XR can be a challenge in 2026, but you have options. Start by using Medfinder to locate pharmacies with your medication in stock. If that doesn't work, reach out to independent pharmacies, talk to your doctor about alternatives, and explore patient assistance programs.
