Risperidone is used to manage symptoms of:
Schizophrenia: Risperidone is prescribed to manage schizophrenia in adults and children over 13.
Bipolar disorder: Risperidone is prescribed to treat mania symptoms (abnormally excited or irritated moods) in adults and children over 10. Autism: Risperidone is prescribed to children between 5-16 with autism to manage irritability (characterized by aggression and mood changes)

Risperidone belongs to a class of drugs known as atypical antipsychotics. It is a dopamine and serotonin antagonist. Dopamine and serotonin are naturally occurring chemicals in your brain (known as neurotransmitters) that are known to regulate your mood. It’s thought that people who suffer from schizophrenia, bipolar disorder, and autism have an imbalance of certain neurotransmitters. Risperidone may help to improve this imbalance by blocking dopamine and serotonin receptors.
