How this service works
FDA drug label lookup: boxed warning, approved indications, contraindications, warnings and drug interactions for any drug, plus brand and generic names, manufacturer and route, as clean structured text from openFDA. Not medical advice.
Output
Returns clean structured text fields from the openFDA drug label database, including: boxed warnings (black box warnings), approved indications, contraindications, warnings and precautions, drug interactions, brand and generic names, manufacturer name, and route of administration.
Example use cases
Checking drug interaction warnings
“What does the FDA label say about drug interactions and contraindications for warfarin? I want to see the boxed warnings too if there are any.”
Verifying approved indications for a prescription
“Look up the FDA-approved indications for semaglutide — I want to know exactly what conditions it's officially approved to treat and what warnings are on the label.”
Researching a new medication before prescribing
“Pull the full FDA label data for methotrexate — I need the boxed warnings, route of administration, manufacturer, and any major drug interactions listed.”

Endpoint
GEThttps://www.x402pulse.dev/v1/health/drug-label?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, regulatory-sourced FDA label information about a specific drug — particularly boxed warnings, approved indications, contraindications, or drug interactions — rather than general drug information from non-regulatory sources. Ideal for clinical decision support tools, medication safety checks, or any agent workflow where the official FDA-approved label text is required. Prefer this over general drug information APIs when regulatory accuracy and structured output are priorities.
Side effects
- Drug name not found in openFDA database — returns empty or no-match response
- Ambiguous drug name matching multiple products — may return data for the wrong product
- openFDA upstream outage or rate limiting — endpoint may return an error
- Drug label data may be incomplete if FDA records are sparse for that drug
- Very new or obscure drugs may not yet have structured label data in openFDA
