FAQPage Schema
How do I query FDA adverse events from FAERS data?

You can query FDA adverse events from FAERS data by using the openFDA Drug Event API to surface drug safety signals. The Skill returns top adverse reactions with counts and metadata for single-drug lookups or small batches.

What is the best way to detect drug safety signals from openFDA data?

Detecting drug safety signals from openFDA data involves querying the FAERS database to retrieve top adverse reactions with occurrence counts. This Skill summarizes results in a concise, LLM-friendly format for downstream analysis and reporting.

Can I query adverse events for multiple drugs in a batch?

Yes, you can query adverse events for multiple drugs in small batches using the count_reactions_batch function. It processes small batches of drugs against the openFDA Drug Event API and returns reaction counts and metadata for each drug.

Does querying openFDA FAERS data require an API key?

Querying openFDA FAERS data does not require an API key, but providing an optional api_key increases your request limits. The Skill also allows configuring the top_n reactions returned and a timeout threshold for the API calls.

What limitations exist when using openFDA for post-market drug safety surveillance?

Limitations of using openFDA for post-market drug safety surveillance include API rate limits and query timeouts that can restrict large batch processing. The Skill is designed for single-drug lookups and small batches, not exhaustive evidence synthesis.

How does FAERS data summarize adverse events for LLM downstream analysis?

FAERS data summarizes adverse events for LLM downstream analysis by formatting the openFDA query results into a concise text summary. The summarize_reactions function aggregates top reaction counts and metadata into an LLM-friendly output for validation and reporting.
