How Does Invega Sustenna Work?Invega Sustenna belongs to a group of medicines known as atypical antipsychotics (also called second-generation antipsychotics). It is thought to work by blocking the action of dopamine, a neurotransmitter (chemical) in the brain that is believed to be elevated in people with schizophrenia. Like other atypical antipsychotics, Invega Sustenna also blocks a type of serotonin (another chemical found in the brain) receptor, which is believed to help control some of the symptoms of schizophrenia.
Invega Sustenna is given as an injection into a muscle. After each dose, the medication is removed from the body slowly, allowing for once-a-month dosing.
