Invega® (paliperidone) is a prescription drug used to treat schizophrenia and schizoaffective disorder. Information concerning the specific effects, dosing guidelines, and potential side effects of the medication should be discussed with your healthcare provider before treatment begins.
In clinical studies of Invega for the treatment of schizophrenia, people taking it experienced significant improvements in their schizophrenia symptoms (including hallucinations and suspiciousness). Longer studies also showed that the medicine can help prevent hospitalization due to schizophrenia and can help prevent symptoms from returning.
Invega comes in tablet form and is typically taken once a day, in the morning. The tablets are specially designed to slowly release the medication over time. They should be swallowed whole with water (or other liquids) and should not be crushed, chewed, or broken. A long-acting injectable form (Invega Sustenna™) is also available.
As with any drug, side effects are possible with Invega. Some of the most common side effects that have been reported with this drug include a rapid heart rate, headaches, drowsiness, and feelings of internal restlessness or jitteriness.
