What might be a reason for someone developing habituation toward a medication?

Habituation towards a medication typically occurs with long-term repeated use. When a person consistently uses a medication, their body can adapt to its effects, leading to diminished responses over time. This adaptation may result in the individual requiring higher doses of the medication to achieve the same therapeutic effect that they initially experienced. Factors like tolerance and physiological changes contribute to this habituation process, underscoring the importance of monitoring long-term medication use to prevent potential complications or the need for increased dosages. The other options do not directly relate to habituation: an overdose can lead to toxicity, abstinence implies discontinuation rather than regular use, and acute reactions generally involve immediate responses rather than long-term adjustments.
