What is Risperidone?
Risperidone is a prescription antipsychotic medication used to treat schizophrenia in adults and adolescents, bipolar disorder (manic episodes), and irritability associated with autism spectrum disorder (ASD) in children. It belongs to a class of drugs called atypical (second-generation) antipsychotics. Risperidone works by balancing the activity of dopamine and serotonin in the brain — two neurotransmitters that play a key role in mood, perception, and behavior. This helps reduce hallucinations, delusions, disorganized thinking, and mood instability. Doses range from 0.5 mg to 16 mg per day depending on the condition and the patient's age. If you or a loved one may benefit from risperidone, a licensed psychiatric provider can evaluate symptoms and prescribe appropriately through Rx.com telehealth.Side Effects

What is risperidone and how does it work?
Risperidone is an atypical (second-generation) antipsychotic. It is FDA-approved to treat schizophrenia in adults and adolescents 13 and older; to treat acute manic or mixed episodes of bipolar I disorder (alone in adults and children 10 and older, or combined with lithium or valproate in adults); and to treat irritability associated with autistic disorder in children and adolescents ages 5 to 16, including aggression, deliberate self-injury, and temper tantrums. Long-acting injectable forms such as Risperdal Consta and Perseris are used for the ongoing maintenance treatment of schizophrenia.
Risperidone is thought to work by adjusting the activity of dopamine and serotonin, two natural chemicals in the brain that affect mood, thinking, and behavior. It is sold under several brand names, including Risperdal, Risperdal Consta, Perseris, Uzedy, and Rykindo. Your prescriber will choose the form and dose that fits your needs. This page is general information, not medical advice.
How much does risperidone cost without insurance?
Risperidone is available as a generic, which usually makes the oral tablets and solution far cheaper than the brand-name Risperdal. Even so, cash prices are not the same everywhere, so it pays to compare. The same prescription can cost noticeably more at one pharmacy than at another just a few miles away, which is exactly why checking prices before you fill matters.
Rx.com compares real-time cash prices across more than 60,000 U.S. pharmacies and gives you a free coupon you can use at the register, with or without insurance. Enter your ZIP above to see today's price for your dose and quantity. The manufacturer, Johnson & Johnson, also offers cost-support programs for some of its branded risperidone products through its official patient site; eligibility and terms vary, so check directly with them. Long-acting injectable versions are generally more expensive than the generic oral tablets.
Risperidone alternatives and related medications
Risperidone belongs to the same class as several other atypical antipsychotics. Paliperidone is closely related and is actually the active metabolite of risperidone. Other medicines a prescriber may consider for similar conditions include aripiprazole, quetiapine, olanzapine, and ziprasidone. These drugs differ in their side-effect profiles, dosing, and how they are taken.
Only your prescriber can decide which medication is right for you, and you should never switch or stop an antipsychotic on your own. If cost is a factor in that conversation, you can compare the cash price of risperidone and its alternatives on Rx.com to bring real numbers to your appointment.
Risperidone safety and side effects
Risperidone carries a boxed warning: elderly patients with dementia-related psychosis who are treated with antipsychotics have an increased risk of death, and risperidone is not approved to treat dementia-related psychosis. Common side effects can include drowsiness, dizziness, and weight gain. More serious risks that need medical attention include neuroleptic malignant syndrome (NMS), tardive dyskinesia (abnormal movements that may be permanent), metabolic changes such as high blood sugar or new diabetes, high cholesterol, and increased prolactin levels that can cause breast changes or menstrual and sexual problems.
Other reported risks include a sharp drop in blood pressure when standing (which can cause fainting), low white blood cell counts, seizures, trouble swallowing, and rarely a prolonged, painful erection (priapism). Risperidone can impair alertness and coordination, so use caution when driving until you know how it affects you. Used in the third trimester of pregnancy, it may cause muscle and withdrawal symptoms in newborns. This is not a complete list. Talk with your doctor or pharmacist about your full history and all your medicines, and call your provider right away if you notice a worrying reaction.
