Which of the following is NOT a side effect of medications?

The correct answer is that "Change in taste only" is NOT considered a side effect of medications. While taste changes can occur as a result of certain medications, it is not commonly recognized as a distinct side effect on its own. Side effects typically encompass a range of physiological or psychological changes, such as changes in behavior, weight gain, and mood, which can be more significant or noticeable to the patient.

Change in behavior can result from various medications, especially those affecting the central nervous system, and weight gain is a well-documented side effect due to hormonal changes, metabolic factors, or drug-specific actions. Similarly, mood changes are frequently reported with various pharmaceuticals, particularly those in psychotropic categories. In this context, focusing on "Change in taste only" highlights the specificity and potential insignificance of that side effect relative to the broader and more impactful side effects associated with medications.
