`fda_faers_trend`

Pack: openfda · Endpoint: https://gateway.pipeworx.io/openfda/mcp

Aggregate daily FAERS report counts into calendar months for a drug and optional reaction over a bounded date window. The reaction argument matches one whole MedDRA preferred term, so a broad word like “neuropathy” counts only reports filed under that exact term and not the specific terms containing it. Natural multi-word phrasing is resolved to MedDRA word order and disclosed; a term matching nothing is reported as unresolved rather than as zero reports. Trends reflect reporting activity, publicity, utilization, duplicates, and database updates—not incidence or changing clinical risk.

Parameters
