Drug Label Diff Tracker (DailyMed)
Pricing
Pay per usage
Watches FDA drug label (SPL) versions on your watchlist via the official NIH/NLM DailyMed API and emits section-level before/after diffs for safety sections (boxed warning, contraindications, warnings & precautions, adverse reactions) with severity heuristics and stable IDs.
DailyMed SETIDs (UUID-shaped) to watch directly. Find them in the label URL, e.g. dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=…
[]NDC codes (hyphenated or plain digits). Each is resolved to its DailyMed label(s) via the official search endpoint.
[]RxNorm RxCUIs (numeric). Ingredient-level codes can match many labels; results are capped per identifier (newest-published first) by 'Resolution cap per identifier'.
[]incremental: only labels whose current version changed since the last run are re-diffed (a status row is always written per label). full: re-diff every label against its prior version regardless of stored state.
Which LOINC-coded top-level label sections to extract and diff.
[ "boxed_warning", "contraindications", "warnings_precautions", "adverse_reactions"]Upper bound on records saved to the dataset this run (status rows + section diffs combined). Labels cut off by this cap are re-checked next run.
Include the capped added/removed text lines in each section diff record (counts and metrics are always included). Disable for leaner output.
Cap on kept added/removed lines per section diff; excess lines are counted but not stored.
When an NDC/RxCUI matches many labels, keep at most this many per identifier (newest-published first, deterministic tiebreak). The full match count stays reported in the run summary.
