- getLabelHistoryGet the full version history of one DailyMed label (every published SPL version with its date), the label's Recent Major Changes section (which sections changed and when, PLR labels only), its FDA application numbers and product NDCs. Answers 'when was this label last updated' and 'how often does it change'; use compareLabelVersions to see the actual text that changed.Free
- searchLabelsSearch DailyMed structured product labels (SPL) by drug name, NDC, RxCUI, application number or labeler, optionally only labels published since a date. Returns each label's setId, current version number and publication date, newest first. Use publishedAfter for 'which labels changed since X'; pass a setId to getLabelHistory or compareLabelVersions. One drug can have several labels (brand, repackagers, generics).Free
- compareLabelVersionsShow what changed in a DailyMed drug label between two versions: sections added, removed or modified, with the added and removed sentences. Give sinceDate to compare the label in force at that date with the current one ('what changed in the label since X'), or explicit versions from getLabelHistory. Defaults to the latest change (previous version vs current). Sentence-level diff of the SPL text; tables are flattened.Free
