Which statement best defines an adverse drug event?

• A. Minor side effects that are harmless
• B. Any injury or harm related to a drug
• C. An event unrelated to medication
• D. An event that requires no reporting

Answer: (B)

An adverse drug event means any injury or harm that is related to a drug. This broad idea covers more than just obvious, intolerable side effects: it includes harm from proper or improper use, dosing errors, drug interactions, overdoses, and allergic reactions. So the key point is that the event is tied to the drug and results in harm. The other options don’t fit because: - Minor side effects that are harmless aren’t injuries or harm from a drug. - An event unrelated to medication isn’t an adverse drug event. - An event that requires no reporting ignores the pharmacovigilance aspect; many ADEs should be reported to monitor drug safety. So the best definition is an injury or harm related to a drug.
