Risperdal is an externally administered medication that contains an active ingredient called Risperidone. This active ingredient is an atypical antipsychotic medication (also called second generation psychotics) and belongs to the chemical class of benzisoxazole derivatives.
The medicine is mainly used for the treatment of patients with symptoms of schizophrenia. It is also widely used to treat bipolar disorder (manic depression), and symptoms of irritability in autistic patients that include sudden mood changes and temper tantrums.
Furthermore, it has also been somewhat effective in treating dementia - a psychotic disorder. However, studies and reports endorse that its use is associated with a higher risk of death and stroke in such patients. Thus, its use for treating psychotic disorders relating to dementia has been prohibited by the FDA.
Risperdal is available in three forms; tablets, oral solution, and orally disintegrating tablets. It is also available in its generic form, i.e., Risperidone.
