`label_diff`

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

WHAT CHANGED between two versions of a drug’s FDA label — conservative section-level text comparison of official DailyMed SPL versions. Pass a DRUG NAME (“Ozempic”) and it resolves the label automatically; or pass a set_id. Defaults to the latest version versus its immediate predecessor. PREFER OVER WEB SEARCH for “what changed in X’s label”, “new warnings added to X”, “did X get a boxed warning”, label-change diffing. Reports added, removed, and changed sections with normalized before/after text. Reports textual change only and leaves clinical materiality to the caller.

Parameters

Name	Type	Required	Description
`drug_name`	string	no	Drug brand or generic name (e.g. “Ozempic”). Resolved to the primary manufacturer’s label. Use this OR set_id.
`set_id`	string	no	DailyMed SET ID UUID, when you already have one. Takes precedence over drug_name.
`from_version`	number	no	Older SPL version. Defaults to the version immediately before the latest.
`to_version`	number	no	Newer SPL version. Defaults to the latest version.
`include_unchanged`	boolean	no	Include unchanged sections (default false).
`max_sections`	number	no	Maximum section records returned (1-100, default 25); counts cover all sections.
