An Overview of Acute Drug Overdose and Poisoning in Emergency Medicine

Abstract

Acute drug overdose and poisoning are critical concerns in emergency medicine, often arising from both intentional and unintentional exposures to harmful substances. Poisoning occurs when a substance causes harm through its chemical effects, whereas an overdose usually involves taking an excessive amount of drugs, whether by accident or on purpose. The rising incidence of drug overdoses, particularly involving opioids, sedatives and stimulants, poses significant challenges to healthcare providers. Risk factors for overdose include individual characteristics such as male gender, chronic health conditions and prior overdose experiences. Drug-related factors, including polydrug use and the route of administration, also contribute to overdose risk. Timely intervention is crucial in managing overdoses, with treatments varying based on the substance involved. For instance, opioid antagonists like naloxone are vital in reversing opioid overdoses. Prevention strategies, including harm reduction and expanded access to naloxone, are essential in addressing this public health issue. Recognizing the symptoms, risk factors and treatment options for acute drug poisoning is crucial for enhancing patient outcomes and lowering mortality rates.
