Invega® (paliperidone) is a prescription drug commonly used for the treatment of schizophrenia and schizoaffective disorder. It belongs to a class of medications known as atypical antipsychotics. Although most people respond well to it, you may want to consider an Invega substitute if you experience any side effects or do not see an improvement in your symptoms.
A number of medications can be used as a substitute for Invega, including other atypical antipsychotics and typical antipsychotics.
Atypical antipsychotics are usually effective at treating schizophrenia. It is thought that these newer antipsychotic medications may have fewer serious side effects than older antipsychotics (although studies have shown conflicting results). In addition to Invega, these medications can include:

- Olanzapine (Zyprexa®)
