What could indicate a medication overdose?

Confusion or drowsiness is a significant indicator of a medication overdose. When a person experiences an overdose, their body may struggle to process the excess medication, leading to various neurological symptoms such as confusion, sedation, or drowsiness. These symptoms arise because the central nervous system can be profoundly affected by high levels of certain medications, especially sedatives or narcotics.

In contrast, the other options do not typically signal an overdose. For instance, increased appetite and improved mood can occur for various legitimate reasons, including other medical conditions or adjustments in medication that are not associated with overdose. Increased physical strength might reflect a temporary boost in energy or motivation but does not correlate with the effects of an overdose. Recognizing the signs of overdose is crucial, as it can guide timely intervention to prevent further complications.
