Invega® (paliperidone) is a prescription medicine used for the treatment of schizophrenia in adults and adolescents, and schizoaffective disorder in adults. It belongs to a class of medications known as atypical antipsychotics. The medication comes in tablet form and is available in four different strengths.
The recommended starting Invega dose for schizophrenia treatment or schizoaffective disorder treatment in adults is 6 mg daily. The medication should be taken once a day, in the morning. If needed, your healthcare provider can increase your dosage up to 12 mg once daily in the morning. People with kidney disease may need a lower dose (such as Invega 1.5 or 3 mg once daily). For adolescents, the starting dosage is usually Invega 3 mg once daily.
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 and is given just once a month.
