FAQs

How is a serious adverse event different from an adverse event?

A serious "adverse event" (SAE) is a specific type of adverse event that is life-threatening, requires hospitalization, results in persistent disability, or is otherwise considered medically significant. Not all adverse events are classified as serious.

What are some common examples of adverse events in clinical trials?

Common examples of "adverse events" in clinical trials can include nausea, headache, fatigue, or more serious reactions depending on the medication or intervention being studied.

When should I use the term "adverse event" instead of "side effect"?

"Adverse event" is a broader term that encompasses any undesirable experience associated with a medical product or intervention, while "side effect" typically refers to a known, but unintended, effect of a treatment. Use "adverse event" when the causality is not yet established, and "side effect" when the effect is a recognized consequence.

What is the regulatory significance of reporting adverse events?

Reporting "adverse events" is crucial for post-market surveillance of drugs and medical devices. It allows regulatory agencies to identify potential safety issues and take appropriate actions to protect public health.
