Risperidone is a type of drug called an atypical antipsychotic. It is sold under a variety of brand names including Belivon, Rispen and Risperdal.
Risperidone is used to treat some of the symptoms of schizophrenia, bipolar disorder and other mental health problems.
Risperidone is believed to work by changing the amount and action of several neurotransmitters in the brain, in particular serotonin and dopamine.
Risperidone is sometimes used to treat problem behaviours in autistic people, including aggression, self-injurious behaviours and sudden mood changes.
