Before taking Invega Hafyera injection

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.

Tell your doctor if you have ever had:

heart problems, or a heart attack;

long QT syndrome (in you or a family member);

high or low blood pressure, or fainting spells;

low white blood cell (WBC) counts;

a serious neurologic disorder caused by taking an antipsychotic medicine;

uncontrolled muscle movements in your face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement);

seizures or epilepsy;

an electrolyte imbalance (such as low blood levels of potassium or magnesium);

diabetes (in you or a family member);

cancer of the breast; or

liver or kidney disease.

It is not known if paliperidone will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

Using antipsychotic medicine in the last 3 months of pregnancy may cause serious problems in the newborn. Tell your doctor right away if you get pregnant.
