Risperdal belongs to a group of medications called atypical (or second-generation) antipsychotic medications. It is not entirely known how the drug works for the treatment of schizophrenia or bipolar disorder. However, it is known to block or lessen the effects of several chemicals in the brain. These chemicals (such as dopamine and serotonin) may be elevated in people with schizophrenia, bipolar disorder (also known as manic depression), or autism.
