The liver breaks down the medicine into its active chemical ingredients called metabolites. This helps balance the chemicals in the brain and decreases psychotic and aggressive behavior. Doctors also prescribe the drug “off label”— or without FDA approval — to treat attention deficit hyperactivity disorder (ADHD), anxiety, sleep difficulties and depression. Reviewer specialties include internal medicine, gastroenterology, oncology, orthopedic surgery and psychiatry.

What are the side effects of Risperidone (Risperdal)?

No dosing data are available for children who weigh less than 15 kg. Postmarketing experience includes reports of acute RISPERDAL® overdosage, with estimated doses of up to 360 mg. In general, the most frequently reported signs and symptoms are those resulting from an exaggeration of the drug’s known pharmacological effects, i.e., drowsiness, sedation, tachycardia, hypotension, and extrapyramidal symptoms. Other adverse reactions reported since market introduction related to RISPERDAL® overdose include prolonged QT interval and convulsions. Torsade de pointes has been reported in association with combined overdose of RISPERDAL® and paroxetine. Additional safety and efficacy information was also assessed in one long-term (6-month) open-label extension study in 284 of these adolescent patients with schizophrenia.

International Patients

Somnolence was the most commonly observed adverse reaction in the clinical trial of bipolar disorder in children and adolescents, as well as in the schizophrenia trials in adolescents. As was seen in the autistic disorder trials, these adverse reactions were most often of early onset and transient in duration [see ADVERSE REACTIONS]. Patients experiencing persistent somnolence may benefit from a change in dosing regimen [see DOSAGE AND ADMINISTRATION]. Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group.

1. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for RISPERDAL® and any potential adverse effects on the breastfed child from RISPERDAL® or from the mother’s underlying condition.
2. Your doctor may give you a lower starting dosage of 0.5 mg taken twice per day.
3. To judge the drug’s efficacy, scientists used the Brief Psychiatric Rating Scale, which evaluates the effects of drug treatment in schizophrenia patients.
4. Therefore, RISPERDAL® is not expected to substantially inhibit the clearance of drugs that are metabolized by this enzymatic pathway.
5. Although not all of these side effects may occur, if they do occur they may need medical attention.

Dosage for schizophrenia

These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Risperidone may interfere with elimination by the kidneys of clozapine (Clozaril), a different type of antipsychotic medication, causing increased levels of clozapine in the blood. This could increase the risk of side effects from clozapine. Another important side effect which may also occur include extrapyramidal effects (sudden, often jerky, involuntary motions of the head, neck, arms, body, or eyes) also occur.

What are the side effects of risperidone?

The main metabolite, 9-hydroxyrisperidone, has similar pharmacological activity as risperidone. Consequently, the clinical effect of the drug results from the combined concentrations of risperidone plus 9-hydroxyrisperidone. Safety and effectiveness of RISPERDAL® in children less than 13 years of age with schizophrenia have not been established. RISPERDAL® (0.25 mg twice daily) did not show a clinically relevant effect on the pharmacokinetics of digoxin.

Do not stop using Risperdal Consta without your doctor’s advice. Risperdal Consta is not approved for use in older adults with dementia-related psychosis. Risperdal Consta (risperidone) is a long-acting injection used in adults to treat schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Drinking alcohol can increase certain side effects of this medicine.

Once sufficient clinical response has been achieved and maintained, consider gradually lowering the dose to achieve the optimal balance of efficacy and safety. When fluoxetine or paroxetine is co-administered with RISPERDAL®, the dose of RISPERDAL® should be reduced. The RISPERDAL® dose should not exceed 8 mg per day in adults when co-administered with these drugs. When initiating therapy, RISPERDAL® should be titrated slowly.

Before each dose, patients should open the package with clean, dry hands. It’s important to place the entire tablet on the tongue right away finasteride because the tablet cannot be stored once it’s out of its packaging. Unfortunately, what makes Risperdal work may also cause side effects.

The exact mechanism of action of risperidone is not known, but, like other anti-psychotics, it is believed that risperidone affects the way the brain works by interfering with communication among the brain’s nerves. Nerves communicate with each other by making and releasing chemicals called neurotransmitters.

If directed, you may mix the measured dose with a small amount of liquid (3 to 4 ounces/about 100 milliliters) such as water, coffee, orange juice, or low-fat milk. It may take up to several weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve. Stop using Risperdal and call your doctor at once if you have fever, when good tv goes bad stiff muscles, confusion, sweating, fast or uneven heartbeats, restless muscle movements in your face or neck, tremor (uncontrolled shaking), trouble swallowing, feeling light-headed, or fainting. While you are taking this medicine, you may be more sensitive to temperature extremes such as very hot or cold conditions. Avoid getting too cold, or becoming overheated or dehydrated.
