What is Invega?
Invega is a brand-name prescription medication used to treat schizophrenia and schizoaffective disorder [1]. Its active ingredient is paliperidone, which is an atypical antipsychotic [1]. Invega works by altering the activity of certain chemicals in the brain that can cause the symptoms of these conditions [1].
When does Invega patent expire?
The patent expiration dates for Invega and its related formulations are critical for the entry of generic alternatives.

These dates determine when other manufacturers can legally produce and market generic versions of the drug.
