Paradoxical reaction refers to which concept?

• A. A drug reaction that causes the opposite effect of what is expected
• B. A reaction that enhances the desired effect
• C. A local reaction
• D. An adverse drug reaction that is always severe

Answer: (A)

A paradoxical reaction is when a medication produces the opposite of the intended or expected effect. Instead of calming or relieving symptoms, the drug may cause agitation, restlessness, or increased activity in some people. This contrasts with a local reaction, which occurs at the site of administration, and with an effect that simply enhances the desired response. It also isn’t defined by severity—paradoxical reactions can be mild or more noticeable, but the hallmark is the opposite outcome from what was expected. If you observe this, stop or adjust the medication as advised and report it to the supervisor.
