You should also make sure to tell your healthcare provider about all other medicines you may be taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Paliperidone belongs to a group of medications called atypical (or second-generation) antipsychotic medications. It is not entirely known how paliperidone works for the treatment of schizophrenia. However, it is known that the drug blocks or lessens the effects of several chemicals in the brain. These brain chemicals (such as dopamine and serotonin) may be elevated in people with schizophrenia.
Paliperidone is not a cure for schizophrenia or schizoaffective disorder. It only helps to control symptoms (see Symptoms of Schizophrenia).
