What is a common side effect of using Demerol for pain management?

Respiratory depression is a well-documented side effect associated with the use of Demerol (meperidine), which is an opioid analgesic. This medication works by binding to opioid receptors in the brain, which can lead to a decrease in the respiratory drive. As the dose increases, or in sensitive populations such as the elderly or those with respiratory conditions, the risk of respiratory depression becomes more pronounced. It’s crucial for healthcare providers to monitor patients for signs of respiratory distress when administering opioids like Demerol, ensuring that they maintain adequate respiratory function during treatment.

In contrast, while cardiac arrest, bradycardia, and hives can occur in some patients due to various reasons, these are less common and not typical side effects directly associated with Demerol. Cardiac arrest is a severe and rare reaction, bradycardia can result from multiple factors and is not a primary concern with Demerol, and hives indicate an allergic reaction that is not typically from this medication in most cases. Therefore, respiratory depression stands out as the most relevant and common side effect with Demerol usage.
