Summary Of FDA Black Box Warnings
The U.S. Food and Drug Administration (FDA) has issued a black box warning for paliperidone (invega), stating that the drug may increase the risk of death when used to treat elderly patients with dementia-related psychosis. The FDA also warns that paliperidone can cause serious side effects, including tardive dyskinesia and hyperglycemia (high blood sugar levels).
Paliperidone may also cause orthostatic hypotension, a sudden drop in blood pressure when you stand up from sitting or lying down. This can lead to fainting or dizziness and increases your risk of falling. The FDA recommends that doctors start patients on a low dose of paliperidone and increase the dosage slowly over time to minimize these side effects.
The FDA also warns that there is an increased risk of suicidal thoughts or actions in children, adolescents, and young adults who take antipsychotic medications such as paliperidone for major depressive disorder (MDD). The agency recommends monitoring patients closely for worsening depression or suicidal thoughts, especially during the first few months of treatment.

Managing Side-effects of Paliperidone (Invega)
Some tips for managing the side-effects of paliperidone include:
