Invega Sustenna is a type of injection given once a month to treat schizophrenia. It works by blocking the action of certain brain chemicals that are believed to be elevated in people with schizophrenia. It is a long-acting medicine, which allows for once-a-month dosing. Although most people tolerate this prescription drug well, side effects are possible and may include dizziness, headaches, and drowsiness.
Invega Sustenna is manufactured by Janssen Pharmaceutica N.V. for Janssen Pharmaceuticals, Inc.
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.
