The term "adverse drug reaction" explicitly refers to a harmful or unintended reaction that occurs as a direct consequence of taking a medication. It encompasses any negative effects that arise from a drug that is administered at normal doses, distinguishing these reactions from both beneficial effects and mild side effects that may not significantly impact a patient's health.

Adverse drug reactions can range in severity, potentially leading to serious health outcomes or complications. Recognizing this definition is crucial for pharmacy technicians, as it contributes to the safe and effective management of medication therapy in patients. Understanding adverse reactions allows pharmacy professionals to monitor patients effectively, counsel them about potential risks, and report any concerning reactions to ensure patient safety.

The other options do not align with the accepted definition of an adverse drug reaction, as they either describe positive effects or specific scenarios that do not encompass the full scope of harm and unintended reaction that this term signifies.
