Risperidone is an atypical antipsychotic medication used to treat schizophrenia, bipolar disorder, and irritability associated with autism spectrum disorder. It works by blocking dopamine (D2) and serotonin (5-HT2A) receptors in the brain, helping to reduce psychotic symptoms and stabilize mood.

In schizophrenia, risperidone is effective in reducing positive symptoms (such as hallucinations and delusions) and negative symptoms (such as social withdrawal and lack of motivation). In bipolar disorder, it is used to treat acute manic or mixed episodes. It is also indicated for managing irritability and aggressive behaviors in children and adolescents with autism spectrum disorders.

Risperidone is available in the form of tablets, oral solution, or long-acting injectable formulations. The dose is gradually adjusted based on the patient’s response and tolerance. Common side effects include drowsiness, weight gain, dizziness, increased appetite, and extrapyramidal symptoms (such as tremors or muscle stiffness).

Treatment with risperidone should be administered under the supervision of a doctor, and patients should be regularly monitored to assess effectiveness and manage potential side effects. It is important for patients to follow the prescribed dosage and not discontinue treatment without consulting their doctor.
