What can be a consequence of administering a drug outside its dosage range?

Administering a drug outside its dosage range can lead to serious consequences, including the potential for severe side effects or toxicity. Each medication has a specific therapeutic range, which is the dosage range in which it is safe and effective. If a dose exceeds this range, it can overwhelm the body's ability to process the medication, leading to adverse reactions, including toxic effects on organs or systems. These adverse reactions can sometimes be life-threatening, necessitating immediate medical intervention.

While it is possible that some drugs might show reduced efficacy or enhanced effectiveness when dosed inappropriately, the most concerning consequence of crossing the established dosage limits is the heightened risk of toxicity, which poses a clear risk to patient safety and health. Hence, the correct answer emphasizes the critical nature of adhering to prescribed dosage ranges to avoid potentially dangerous outcomes.
