Risperidone
Summary
Risperidone is used to treat mental health conditions like schizophrenia, which involves distorted thinking and perception, and bipolar disorder, which causes extreme mood swings. It also helps manage irritability in children with autism, which is a developmental disorder affecting communication and behavior.
Risperidone works by balancing chemicals in the brain called neurotransmitters, which help transmit signals between nerve cells. It mainly targets dopamine and serotonin receptors, which are involved in mood and behavior regulation, reducing symptoms like hallucinations, which are false perceptions, and mood swings.
Risperidone is usually taken orally, which means by mouth, once or twice daily. The starting dose for adults is typically 1 mg twice daily, and the maximum recommended dose is 16 mg per day. Dosages for children and the elderly are lower and adjusted carefully by a doctor.
Common side effects of Risperidone include drowsiness, which is feeling sleepy, dizziness, which is feeling lightheaded, and weight gain. These effects can vary in severity and may affect more than 10% of people taking the medication. It's important to discuss any new symptoms with your doctor.
Risperidone can increase the risk of stroke in elderly patients with dementia-related psychosis, which is a mental disorder. It may also cause tardive dyskinesia, which involves involuntary movements. People with known allergies to Risperidone should not use it. Always follow your doctor's instructions and report unusual symptoms.
