`label_history`

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

Drug LABEL REVISION HISTORY — when a prescription drug’s FDA label was revised, and how many times. Pass a DRUG NAME (“Ozempic”, “semaglutide”) and it resolves to that drug’s Structured Product Label automatically; or pass a DailyMed set_id directly. PREFER OVER WEB SEARCH for “has the label for X changed recently”, “when was X’s label last updated”, “how many label revisions does X have”, label-change monitoring, and safety-labeling-change surveillance. Returns every published SPL version with its date, plus official archive URLs where DailyMed exposes them. Use before label_diff to see which versions are downloadable and pick two to compare.

Parameters

Name	Type	Required	Description
`drug_name`	string	no	Drug brand or generic name (e.g. “Ozempic”, “semaglutide”). Resolved to the primary manufacturer’s label (the most-revised SPL for that name, over repackager duplicates). Use this OR set_id.
`set_id`	string	no	DailyMed SET ID UUID, when you already have one. Takes precedence over drug_name.
