## When to prefer this

Use this endpoint when you need authoritative, official FDA labeling data — particularly indications, dosage, warnings, boxed warnings, or contraindications — rather than general web summaries. Prefer it for clinical, compliance, or patient-safety contexts where regulatory accuracy matters. It accepts both brand and generic drug names, making it flexible for real-world usage.

## Known failure modes

- Unknown or misspelled drug name returns no results or an error
- Very new drugs not yet in FDA label database may be missing
- Generic vs brand name ambiguity may return partial results
- Drug not approved by FDA returns empty result
- Network or service timeout at upstream FDA data source
