How this service works
FDA drug labels (package inserts) by brand or generic name from openFDA, newest label first: brand, generic name, manufacturer, indications and usage, warnings, label date. ?q=ibuprofen; 5 labels by default, up to 25 with &limit=. Answers are cached for up to 24 hours. Not medical advice.
Output
Returns a JSON object containing matched drug label records from the OpenFDA database, including brand name, generic name, manufacturer, product type, route of administration, indications and usage, warnings, set ID, and metadata such as total result count, query string, source URL, cache status, and fetch timestamp.
Example use cases
OTC drug safety check
“What are the warnings and indications listed on the FDA label for acetaminophen? I want to know if it's safe to take with other medications.”
Generic drug manufacturer lookup
“Who manufactures the generic version of metformin and what product type does the FDA classify it as? Pull the label info for me.”
Drug brand name research
“Can you search the FDA drug label database for diphenhydramine and tell me what brand names it's sold under and what it's indicated for?”

Endpoint
GEThttps://api.maxwellinternational.ai/v1/openfda/drug/label?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need structured, FDA-sourced drug labeling data including indications, warnings, and manufacturer information. It proxies the OpenFDA drug label endpoint and adds caching, making it faster than calling OpenFDA directly. Best for agents that need drug safety, regulatory, or pharmaceutical lookup capabilities without needing to manage OpenFDA API keys.
