openlabel diff dupixent --from 53

Dupixent (dupilumab) · v53 (2026-02-23) to v60 (2026-04-22)

  §1.7 Chronic Spontaneous Urticaria · indication, changed
    - DUPIXENT is indicated for … patients aged 12 years and older with chronic spontaneous urticaria (CSU) …
    + DUPIXENT is indicated for … patients aged 2 years and older with chronic spontaneous urticaria (CSU) …

Each section is tagged with a category (boxed warning, indication, dosing, contraindication, warning, adverse reactions, clinical studies, other) and a status (added, removed, changed). Table and figure renumbering is ignored. A label can publish versions with no change to the prescribing information; then diff says so.

Version numbers come from the label’s DailyMed history, which skips numbers.
