Only one company currently supplies this market — there is no backup if it stumbles. Put together: worth watching — several of the pressures that precede supply trouble are present at once. Historically, drugs in this position went on to a new shortage within 90 days about 0.3% of the time — roughly 2× the typical drug (0.1%).

The same NDC has different prices depending on who is paying. Units differ between rungs — compare within a rung over time, not rung against rung, unless the units match.
Each rung is the newest figure for this NDC from one federal price system, shown with its own unit. Part D is matched by drug name because CMS publishes no NDCs there; it is gross spending, before confidential rebates.

No Medicare Part D plan in CMS's quarterly files lists this product. That usually means it is discontinued, a repackager's listing, or a product no plan has added to its formulary.
How Part D pricing works →Manufacturer list price as filed — not what pharmacies actually pay after discounts.
