What is the term for a medication response opposite to the intended effect?

A.

Severe

B.

Allergic

C.

Paradoxical

D.

Toxic

Answer and Explanation

The Correct Answer is C

A. Severe: The term “severe” describes the intensity or seriousness of an adverse reaction, not a reaction opposite to the intended therapeutic effect. It refers to magnitude rather than the direction of the response.

B. Allergic: An allergic reaction is an immune-mediated response to a medication, such as rash, anaphylaxis, or urticaria. It does not describe a response that produces effects opposite to the drug’s intended action.

C. Paradoxical: A paradoxical reaction occurs when a medication produces an effect opposite to that expected, such as a sedative causing agitation or insomnia. This response may be due to individual variation in metabolism, receptor sensitivity, or central nervous system effects.

D. Toxic: Toxicity refers to harmful effects caused by excessive drug levels or accumulation, leading to organ damage or systemic harm. Toxic effects may be exaggerated but are not inherently opposite to the intended therapeutic outcome.
