In clinical studies of Risperdal, people with schizophrenia experienced improvements in their symptoms (including hallucinations and suspiciousness), compared to those not taking it. Other studies have shown that Risperdal can help people from needing to be hospitalized and can help keep symptoms from returning.
Studies have also shown Risperdal to be effective for bipolar disorder treatment. In these studies, the medication was effective at treating episodes of mania or mixed episodes (which involve symptoms of both mania and depression). It was effective when used alone or in combination with other bipolar disorder medications.
When used for treating the emotional symptoms of autism in children, Risperdal resulted in fewer behavior problems, including aggression, self-harm, temper tantrums, and quickly changing moods. Longer studies also showed that Risperdal can help keep these symptoms from returning.
