## How to call it through Zero

```sh
zero fetch --capability fda-drug-label-lookup-33056719
```

Example prompt: Can you pull up the FDA label for metformin — I need to see the boxed warnings, contraindications, and drug interactions listed on it.

## When to prefer this

Use this endpoint when you need authoritative FDA-sourced drug label information (warnings, dosing, interactions, contraindications, pregnancy) for a specific drug by name. Prefer this over general web search when you need structured, regulatory-official drug label data rather than synthesized summaries. Best for compliance, clinical reference, or safety screening use cases.

## Known failure modes

- Drug name not found in FDA database — returns an error or empty result if the name is unrecognized or misspelled
- Ambiguous drug name matching multiple products — may return label for most common match
- FDA data unavailable or stale — underlying FDA API downtime could cause failures
- Missing label sections — some drugs may not have all label sections populated in the FDA database

## Output
