Which of the following adverse effect can occur even after the offending drug has been withdrawn a long time back?
**Core Concept**
The question is testing the concept of drug-induced adverse effects that can persist even after the causative agent has been discontinued. This phenomenon is known as a "late adverse effect" or "delayed adverse effect."
**Why the Correct Answer is Right**
Reversible and irreversible changes can occur in various organs due to drug exposure. For instance, certain medications can cause permanent damage to the liver, kidneys, or lungs, leading to chronic conditions. The liver's ability to regenerate can result in some reversible damage, but certain drugs can induce fibrosis or cirrhosis, which are irreversible and can persist even after the drug is withdrawn. Similarly, certain medications can cause irreversible damage to the kidneys, such as interstitial nephritis or chronic kidney disease.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the adverse effect mentioned is typically reversible and resolves once the causative agent is discontinued.
* **Option B:** This option is incorrect because the adverse effect mentioned is not a well-documented consequence of drug withdrawal.
* **Option C:** This option is incorrect because the adverse effect mentioned is not a typical example of a late adverse effect.
**Clinical Pearl / High-Yield Fact**
Drug-induced liver injury can be reversible, but certain medications can cause irreversible damage, such as fibrosis or cirrhosis, which can persist even after the drug is withdrawn.
**Correct Answer:** C.
