Prefer it over general medical knowledge sources when regulatory accuracy and official labeling language is required, such as for clinical, compliance, or patient safety contexts.

- Ambiguous name matching multiple drugs — may return label for the most common match or require more specificity
- Generic vs. brand name differences may yield different labels
