The main goal of therapeutic drug monitoring is to prevent adverse drug reactions. This practice involves regularly measuring drug levels in a patient's blood to ensure they remain within a therapeutic range that maximizes efficacy while minimizing toxicity. Each medication has a specific range where it is effective without causing harm, and monitoring these levels helps healthcare providers adjust dosages appropriately based on individual patient responses.

When drug levels are too low, the medication may not provide the intended therapeutic effect, while excessively high levels can lead to toxicity and serious side effects. By carefully tracking these levels, healthcare professionals can make informed decisions about treatment adjustments, thereby improving patient safety and treatment outcomes.

Focusing solely on medical history, medication compliance, or drug development does not directly address the immediate concern of ensuring that patients receive safe and effective doses of their medications, which is the primary objective of therapeutic drug monitoring.
