Use this endpoint when you need official FDA-sourced drug label data including structured dosage, warnings, indications, and manufacturer details for a named drug. Prefer this over general web search when regulatory accuracy and structured output are needed. Best for health apps, compliance checks, or agent workflows requiring authoritative pharmaceutical information.

## Known failure modes

- Drug name not found in openFDA database — returns empty or error response
- Ambiguous drug name matching multiple products — may return one representative label
- openFDA upstream API unavailability causing timeout or error
- Very new or rare drugs may not have labels indexed in openFDA
