What is a potential paradoxical reaction risk when using benzodiazepines for sedation?

• A. Paradoxical agitation or excitement
• B. Sedation deeper than intended without relief
• C. Persistent coughing
• D. Hypertension

Answer: (A)

Paradoxical agitation or excitement is a recognized risk with benzodiazepines used for sedation. Although these drugs are intended to calm and sedate, a subset of patients—especially children, the elderly, or those with certain neurodevelopmental or psychiatric traits—can experiences a opposite reaction: they become restless, irritable, or even combative rather than tranquil. This happens because benzodiazepines modulate GABA activity in the brain, and in some individuals this modulation disinhibits certain neural circuits, leading to increased activity instead of suppression. Clinically, this means you must monitor closely after administration, use the lowest effective dose, and be prepared to manage agitation safely (and, if appropriate and safe, consider reversal with flumazenil). This paradoxical response is not about deeper sedation, coughing, or high blood pressure, which are not characteristic of this reaction.
