Risperdal contains the active ingredient risperidone. It is a prescription medication used to treat schizophrenia, acute manic or mixed episodes associated with bipolar I disorder, and irritability associated with autistic disorder.
Risperdal belongs to a group of medications called atypical antipsychotics. It affects the activity of certain chemical messengers in the brain, particularly dopamine and serotonin.
Risperdal is used to treat schizophrenia in adults and adolescents aged 13 years and older. Schizophrenia is a long-term condition that can affect how a person thinks, feels, behaves, and understands reality.
Symptoms may include hallucinations, such as hearing or seeing things that are not present; delusions, which are strongly held beliefs that are not based in reality; disorganized speech or thinking; reduced motivation; social withdrawal; and difficulty expressing emotions.
Risperdal may help reduce these symptoms and improve thinking, behaviour, communication, and daily functioning. It helps manage schizophrenia but does not cure the condition.
Risperdal is used to treat acute manic or mixed episodes associated with bipolar I disorder. It may be used by itself or together with lithium or valproate. It is approved for this use in adults and in children and adolescents aged 10 to 17 years.
A manic episode may cause unusually elevated or irritable mood, increased energy, rapid speech, racing thoughts, reduced need for sleep, impulsive behaviour, or poor judgment. A mixed episode includes symptoms of mania together with symptoms of depression.
Risperdal can help reduce the severity of acute manic or mixed symptoms. However, oral Risperdal is not specifically approved for preventing future manic or depressive episodes, so ongoing maintenance treatment should be determined by a healthcare provider.
Risperdal is also used to treat irritability associated with autistic disorder in children and adolescents aged 5 to 17 years.
In this setting, irritability may include aggression toward others, deliberate self-injury, severe temper tantrums, or rapidly changing moods.
Risperdal does not treat the core features of autism. Instead, it may help reduce specific behaviours that are severe, disruptive, or potentially harmful.
The exact way Risperdal works is not fully understood. It mainly blocks certain dopamine and serotonin receptors in the brain.
Dopamine and serotonin are natural chemical messengers involved in thinking, perception, mood, behaviour, and movement. When their activity becomes unbalanced, symptoms such as hallucinations, delusions, severe agitation, or manic behaviour may occur.
By regulating these chemical signals, Risperdal may help improve thought patterns, reduce psychotic or manic symptoms, and decrease severe irritability and aggression.
Risperdal does not usually provide its full benefit immediately. Some symptoms, such as agitation or difficulty sleeping, may improve earlier, while hallucinations, delusions, thinking problems, or behavioural symptoms may take several weeks to improve.
Take Risperdal exactly as prescribed, even if you do not notice an immediate change. Do not increase the dose or stop treatment suddenly without speaking with your healthcare provider.
Regular follow-up appointments are important so your healthcare provider can assess how well the medication is working and monitor for possible side effects.
Risperdal is taken once or twice daily, depending on the condition being treated and the instructions provided by your healthcare provider.
The correct dose depends on your age, diagnosis, symptoms, response to treatment, medical conditions, and other medications you take. Your healthcare provider will often begin with a low dose and increase it gradually to reduce the risk of side effects.
Before starting Risperdal, tell your healthcare provider and pharmacist about every prescription medication, over-the-counter product, vitamin, and herbal supplement you use. Certain medications can change the amount of risperidone in your body and may require a dosage adjustment.
Do not increase, reduce, or stop Risperdal without medical guidance.
The usual starting dose is 2 mg per day. It may be taken once daily or divided into two doses.
If needed, the dose may be increased by 1 to 2 mg per day at intervals of at least 24 hours. Some patients may need a slower increase.
The recommended dose is generally 4 to 8 mg per day. Although doses between 4 and 16 mg per day have shown effectiveness, doses above 6 mg per day are often associated with more movement-related side effects and may not provide additional benefit.
The safety of doses above 16 mg per day has not been established.
For adolescents aged 13 to 17 years, the usual starting dose is 0.5 mg once daily. It may be taken in the morning or evening.
The dose may be increased by 0.5 mg or 1 mg per day at intervals of at least 24 hours, depending on the response and side effects.
The recommended target dose is 3 mg once daily. The effective dose range is 1 to 6 mg per day, but studies did not show additional benefit above 3 mg per day, and higher doses caused more side effects.
For acute manic or mixed episodes associated with bipolar I disorder, the usual starting dose is 2 to 3 mg once daily.
The dose may be adjusted by 1 mg per day at intervals of at least 24 hours.
The effective dose range is 1 to 6 mg per day. Doses above 6 mg per day have not been adequately studied for bipolar mania.
Risperdal may be used by itself or together with lithium or valproate.
For children and adolescents aged 10 to 17 years, the usual starting dose is 0.5 mg once daily. It may be taken in the morning or evening.
The dose may be increased by 0.5 mg or 1 mg per day at intervals of at least 24 hours.
The recommended target dose is between 1 and 2.5 mg per day. Although doses between 0.5 and 6 mg per day have shown effectiveness, no additional benefit was found above 2.5 mg per day, and higher doses were associated with more side effects.
Risperdal may be prescribed for children and adolescents aged 5 to 17 years who have irritability associated with autistic disorder. The starting dose is based on body weight.
The usual starting dose is 0.25 mg once daily.
After at least four days, the dose may be increased to the recommended dose of 0.5 mg once daily.
If additional symptom control is needed, the dose may be increased by 0.25 mg per day at intervals of at least two weeks.
The usual starting dose is 0.5 mg once daily.
After at least four days, the dose may be increased to the recommended dose of 1 mg once daily.
If additional symptom control is needed, the dose may be increased by 0.5 mg per day at intervals of at least two weeks.
The effective dose range for irritability associated with autistic disorder is generally 0.5 to 3 mg per day. Dosing information is not available for children weighing less than 15 kg.
Not everyone needs the highest recommended dose. Your healthcare provider will aim to find the lowest dose that adequately controls symptoms with manageable side effects.
People with kidney or liver impairment, older adults, and those who are prone to low blood pressure may need a lower starting dose and slower dosage increases.
If Risperdal causes persistent sleepiness, your healthcare provider may divide the total daily dose into two smaller doses.
Take Risperdal exactly as prescribed and at approximately the same time each day. Do not take an extra dose to make up for a missed one, and do not stop treatment suddenly without speaking with your healthcare provider.
Risperdal and its generic alternative Risperidone are available in the following form and strengths:
Risperidone can pass into breast milk and may cause side effects in a nursing infant. Tell your healthcare provider if you are breastfeeding or plan to breastfeed before taking Risperdal.
Watch the baby for unusual sleepiness, poor feeding, restlessness, shaking, muscle stiffness, or uncontrolled movements. Contact the baby’s healthcare provider promptly if any of these symptoms develop. Your healthcare provider can help you weigh the benefits of breastfeeding against the need for treatment.
Risperdal may cause sleepiness, dizziness, slowed reactions, or difficulty thinking clearly. These effects can interfere with driving, operating machinery, or performing other activities that require coordination and full attention.
Avoid these activities until you know how Risperdal affects you. Use extra caution when standing up, especially when treatment begins or the dose is increased, because the medication may also cause dizziness or fainting.
Alcohol can increase sleepiness, dizziness, poor concentration, and impaired judgment while taking Risperdal. It may also increase the risk of falls or other accidents.
Avoid alcohol or ask your healthcare provider whether any amount is safe for you during treatment. Do not combine Risperdal with other substances that cause drowsiness unless your healthcare provider approves them.
Risperdal can make it more difficult for your body to regulate its temperature. This may increase the risk of becoming overheated or dehydrated, especially during strenuous exercise or hot weather.
Drink enough fluids, take breaks in a cool place, and avoid excessive exercise or prolonged exposure to extreme heat. Seek medical attention if you develop a high temperature, heavy sweating or an inability to sweat, confusion, severe weakness, dizziness, or fainting.
Take the missed dose as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular schedule.
Do not take two doses at the same time or take an extra dose to make up for the one you missed. Contact your healthcare provider or pharmacist if you are uncertain about what to do.
The correct Risperdal dose depends on the condition being treated, the patient’s age, symptoms, response to treatment, and other health conditions. For adults with schizophrenia, the usual starting dose is 2 mg per day, not 4 mg. The medication may be taken once daily or divided into two doses. A healthcare provider may gradually increase the dose to a recommended range of 4 to 8 mg per day. Some people may need a lower or higher dose, but doses above 6 mg per day often cause more side effects without providing additional benefit. For adults experiencing an acute manic or mixed episode associated with bipolar I disorder, the usual starting dose is 2 to 3 mg once daily. The effective dose range is generally 1 to 6 mg per day. Lower starting doses are used for children, adolescents, older adults, and people with kidney or liver impairment. Always take Risperdal exactly as prescribed and do not change the dose without speaking with your healthcare provider.
Take the missed dose as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take two doses at the same time or take an extra dose to make up for the one you missed. Contact your healthcare provider or pharmacist if you miss several doses, because you may need instructions before restarting treatment.
Risperdal is approved for certain conditions in children and adolescents, but the minimum age depends on the condition being treated. It may be prescribed for irritability associated with autistic disorder in children and adolescents aged 5 to 17 years, acute manic or mixed episodes associated with bipolar I disorder in patients aged 10 to 17 years, and schizophrenia in adolescents aged 13 to 17 years. The safety and effectiveness of Risperdal have not been established below these ages for the corresponding conditions. Children and adolescents taking Risperdal require careful medical monitoring because the medication may cause weight gain, increased appetite, elevated blood sugar or cholesterol, sleepiness, movement-related side effects, and increased prolactin levels. The healthcare provider will choose the lowest effective dose and monitor the child’s growth, weight, development, symptoms, and possible side effects throughout treatment.
