Adverse Event

An adverse event is any undesirable experience or side effect that occurs during or after the use of a medical treatment, medication, or intervention. It can range from mild issues like nausea to more serious problems such as allergic reactions or complications. Adverse events are important for healthcare providers to identify and monitor because they help ensure patient safety and inform improvements in treatments. Not all adverse events are caused directly by the treatment; some may happen coincidentally. Reporting and analyzing these events helps to develop safer therapies and better patient care.
