Information from the label only; it is not medical advice. Source: openFDA. Information only, not medical advice.
Output

Example use cases

“Before I buy some Advil, can you look up the FDA label to see what warnings and contraindications I should know about, especially around stomach bleeding or heart risks?”
Dosage verification for a medication
“What does the FDA drug label say about the correct dosage for acetaminophen for adults — I want the official instructions, not just a general recommendation.”
Medication information for a health app
“Pull the full FDA label data for naproxen, including its indications, manufacturer, and any contraindications — I need the structured info for a patient-facing health app.”
