1. What INVEGA is and what it is used for

INVEGA contains the active substance paliperidone, which belongs to the group of antipsychotic drugs ( neuroleptics ).

INVEGA is used to treat schizophrenia in adults and adolescents 15 years of age and older.

Schizophrenia is a disease with symptoms in the form of hearing, seeing, or perceiving things that do not exist, have delusions, are overly suspicious, become withdrawn, speak incoherently and have behavioral and emotional impoverishment. People with this disease may also feel depressed, anxious, guilt-ridden, or tense.

INVEGA is also used to treat the schizoaffective disorder in adults.

The schizoaffective syndrome is a psychiatric condition in which the sufferer experiences a combination of different schizophrenia symptoms (such as those listed above) and in addition symptoms of mood disorders (feels a great rush of happiness, feels sad, upset, confused, suffers from insomnia, unusual talk, loses interest for everyday activities, sleeps too much or too little, eats too much or too little and has recurring thoughts of suicide).

INVEGA can help relieve the symptoms of your illness and prevent your symptoms from coming back.
