WARNING

Taking Risperidone Injection, like any medication, comes with potential risks and side effects. It’s important to note that the decision to use this medication is based on a careful assessment of the potential benefits versus the risks by your healthcare provider. Here is a brief overview of the risks associated with Risperidone Injection:

• Extrapyramidal Symptoms (EPS): Risperidone can cause movement disorders such as tremors, stiffness, and uncontrollable movements. In some cases, this can lead to tardive dyskinesia, a condition characterized by repetitive, involuntary movements.
• Metabolic Effects: Risperidone may lead to changes in blood sugar levels, cholesterol levels, and triglycerides, potentially increasing the risk of diabetes and cardiovascular issues.
• Weight Gain: Some individuals may experience weight gain while taking Risperidone.
• Neuroleptic Malignant Syndrome (NMS): This is a rare but serious condition associated with antipsychotic medications, including Risperidone. NMS can cause symptoms such as high fever, muscle stiffness, confusion, and changes in heart rate.
• Cardiovascular Effects: Risperidone has been associated with an increased risk of stroke, especially in elderly individuals with dementia-related psychosis.
• Decreased White Blood Cell Count: Risperidone may lead to a decrease in the number of white blood cells, increasing the risk of infections.
• Sedation and Drowsiness: Risperidone can cause drowsiness, which may impair your ability to perform activities that require alertness.
• Prolactin Elevation: Risperidone may increase levels of the hormone prolactin, leading to side effects such as breast enlargement and lactation in both males and females.
• Seizures: In rare cases, Risperidone may lower the seizure threshold.
• Allergic Reactions: Serious allergic reactions to Risperidone are rare but can occur.

It’s important to discuss these risks with your healthcare provider before starting Risperidone Injection. Your provider will carefully consider your medical history, individual health status, and the potential benefits of the medication in managing your specific condition. If you have any concerns about the risks associated with Risperidone, be sure to address them with your healthcare provider.
