WARNING

Paliperidone is an antipsychotic medication used to treat conditions such as schizophrenia and schizoaffective disorder. When administered as an injection, it’s typically in the form of a long-acting injectable (LAI) called Paliperidone Palmitate.

While paliperidone injection can be effective in managing certain mental health conditions, it is essential to be aware of potential risks and side effects. It’s important to note that individual responses to medication can vary, and not everyone will experience these effects. Some common risks associated with paliperidone injection include:

• Extrapyramidal Symptoms (EPS): These are movement disorders that may include tremors, rigidity, and uncontrollable movements. They can be a side effect of antipsychotic medications.
• Hyperprolactinemia: Paliperidone may increase levels of the hormone prolactin, potentially leading to side effects such as breast enlargement, lactation, and menstrual irregularities.
• Metabolic Effects: Antipsychotic medications, including paliperidone, may contribute to weight gain, increased blood sugar levels, and lipid abnormalities, which could increase the risk of diabetes and cardiovascular issues.
• Orthostatic Hypotension: Paliperidone may cause a drop in blood pressure when standing up, leading to dizziness or fainting.
• Neuroleptic Malignant Syndrome (NMS): This is a rare but serious condition associated with the use of antipsychotic medications. It involves symptoms such as high fever, muscle rigidity, and changes in mental status.
• QT Prolongation: There is a potential risk of prolonging the QT interval on the electrocardiogram (ECG), which could lead to an irregular heart rhythm.

It’s crucial for individuals considering or currently using paliperidone injection to work closely with their healthcare provider. They should discuss their medical history, any existing conditions, and potential risks versus benefits of the medication. Regular monitoring and follow-up appointments are typically recommended to manage and mitigate potential side effects. If any concerning side effects occur, it’s important to seek medical attention promptly. Always follow your healthcare provider’s instructions and report any unusual symptoms or side effects.
