# openlabel diff

> Print every sentence that changed between two label versions.

```sh theme={null}
openlabel diff <drug> [--from <version>] [--to <version>]
```

| Option | Description |
| - | - |
| `--from <n>` | The older version. Defaults to the version before `--to` |
| `--to <n>` | The newer version. Defaults to the current one |
| `--json` | Print the diff as JSON |

```sh theme={null}
openlabel diff dupixent --from 53
```

```text theme={null}
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.
