Why is this medication prescribed?
Invega Hafyera is prescribed for the treatment of schizophrenia in adults. Schizophrenia is a chronic mental disorder characterized by disturbances in thinking, perception, emotions, and behavior. The goal of treatment with Invega Hafyera, an antipsychotic medication, is to reduce or control the symptoms associated with schizophrenia.
Invega Hafyera contains two active ingredients: paliperidone palmitate and risperidone. Paliperidone palmitate is an extended-release formulation that provides a sustained release of paliperidone, the active metabolite of risperidone. It works by blocking the effects of certain neurotransmitters in the brain, primarily dopamine and serotonin, which helps to normalize brain function and alleviate the symptoms of schizophrenia.
Invega Hafyera is specifically indicated for adults with schizophrenia who require long-term maintenance treatment. It is administered by injection once every three months, providing continuous medication levels throughout the treatment period. This long-acting formulation helps to improve medication adherence and reduce the risk of relapse.
