compareLabelVersions

Free

Show 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.
