You should not use this medicine if you are allergic to paliperidone or to risperidone (Risperdal).

Paliperidone may increase the risk of death in older adults with dementia-related psychosis and is not approved for this use.

High doses or long-term use of paliperidone can cause a serious movement disorder that may not be reversible. The longer you use paliperidone, the more likely you are to develop this disorder, especially if you are a woman or an older adult.

Before you receive your first injection, tell your doctor if you have never taken oral (by mouth) paliperidone or risperidone.

  • liver or kidney disease;
  • seizures or epilepsy;
  • an electrolyte imbalance (such as low levels of potassium or magnesium in your blood);
  • diabetes (paliperidone may raise your blood sugar); or
  • breast cancer.

Tell your doctor if you are pregnant or plan to become pregnant while using this medicine.

Using antipsychotic medicine in the last 3 months of pregnancy may cause breathing problems, feeding problems, or withdrawal symptoms in the newborn. However, you may have withdrawal symptoms or other problems if you stop using your medicine during pregnancy. If you get pregnant, tell your doctor right away. Do not stop using paliperidone without your doctor's advice.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of paliperidone on the baby.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.
