How this service works
FDA drug safety snapshot for any drug (brand or generic name): total adverse event reports, share serious and fatal, most-reported side effects and the quarterly report trend from FDA FAERS. Reports are not proof of causation. Data, not medical advice.
Output
Returns a structured drug safety snapshot including: total number of adverse event reports in FDA FAERS, percentage of reports classified as serious, percentage classified as fatal, a ranked list of most-reported side effects, and a quarterly trend of report volume. Includes a disclaimer that reports are not proof of causation and this is not medical advice.
Example use cases
Pre-prescription safety research
“Before I start taking metformin, can you pull the FDA adverse event data for it — how many reports are there, what portion were serious, and what are the most commonly reported side effects?”
Drug comparison safety screening
“I'm writing a report comparing the safety profiles of Xarelto and Eliquis — can you get me the FDA FAERS snapshot for each, including serious and fatal event percentages and the quarterly trend?”
Pharmacovigilance trend monitoring
“Has there been a noticeable uptick in adverse event reports for Humira over recent quarters? Pull the FDA FAERS data and show me the quarterly trend along with the top side effects.”
Technical details
Endpoint
GEThttps://www.x402pulse.dev/v1/health/drug-safety?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured FDA FAERS safety summary for a specific drug by name, especially for adverse event counts, severity breakdown (serious/fatal), top side effects, and trend data. Prefer over FDA drug label lookup when you want real-world post-market safety signals rather than label-approved indications or warnings. Best for pharmacovigilance research, patient safety screening, or drug comparison workflows.
Side effects
- Drug name not found in FAERS — returns empty or zero-count result for misspelled or very new drugs
- Ambiguous drug name matching multiple compounds — may return aggregated or partial data
- FAERS data lag — most recent quarter may not yet be fully populated
- Rate limit exceeded on free tier — HTTP 402 if per-call payment fails
- Generic vs brand name mismatch — querying one may not aggregate the other automatically
