`fda_faers_reaction_profile`

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

Summarize the most frequently co-reported FAERS reactions plus serious/non-serious report counts for a drug. Counts are spontaneous reports with duplicates, co-medications, and reporting bias—not event rates or proof of causation.

Parameters

Name	Type	Required	Description
`drug`	string	yes
`from_date`	string	no	Optional. YYYY-MM-DD. OMIT for all-time counts (the common case). Only specify if the question is about a specific date range — and never set from_date equal to to_date (a zero-width window returns 0).
`to_date`	string	no	Optional. YYYY-MM-DD. OMIT unless from_date is also set. Must be after from_date.
`limit`	number	no
