Risperdal (risperidone) is an atypical antipsychotic drug used by adults and teens to control the extreme emotions, thoughts, and behaviors sometimes associated with several mental health conditions. It is available only through prescription and is often prescribed to treat schizophrenia, but has several other clinical applications.
Treatment with Risperdal
This medication may be used to treat symptoms of schizophrenia, mania or mixed episodes in adults, teens, and children over the age of 10 years, and those who display bipolar symptoms. Risperdal may also be used to help control some of the behaviors associated with autism, such as limited speech activity, motivation, and social isolation, in children aged five to 16. While this medication will help to manage associated symptoms, it will not cure bipolar issues, mania, autism, or schizophrenia.

- How can I get the most out of my Risperdal treatment?
When antipsychotic medications are prescribed to treat mental health conditions, it may be beneficial to consider pairing the drug treatment with a type of psychotherapy that also helps treat what you are experiencing. Finding a therapist or counselor you trust can help you understand the condition you are experiencing better, allow you to explore aspects of it in a safe and non-judgmental setting, and help you develop healthy strategies for when associated behaviors, emotions, or thoughts arise or become triggered. Many pieces of prominent, peer-reviewed research indicate that psychotropic drug treatment combined with therapy may produce better long-term results and a greater quality of life for those experiencing mental health conditions.
