Which term describes any noxious and unintended response to a drug that occurs at a normal dose?

• A. Adverse Event
• B. Adverse Drug Event
• C. Adverse Drug Reaction
• D. Medication Error

Answer: (C)

The term describes a harmful, unintended response that occurs when a drug is used at a normal dose and under usual conditions. This means the body reacts to the drug itself, not because of an error or an overdose. That specific causality and dosing context is what makes the phrase Adverse Drug Reaction the best fit. Think of it this way: an Adverse Drug Reaction is about the drug causing harm at standard use. An Adverse Event is any undesirable medical occurrence during treatment, which might not be caused by the drug. An Adverse Drug Event covers harm from the drug that can include dosing errors or interactions. A Medication Error is about a mistake in how the drug was prescribed, dispensed, or administered, not the drug’s intrinsic reaction.
