13 companies supply this market — deep enough that no single failure threatens the supply. The price has held steady around $1.30 per mL over the past year. Put together: this looks like a healthy supply — the boring kind, which is exactly what you want.
The numbers behind every sentence are on this page below — and the Watch button emails you when any of them move.
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.
Pipeline and calculations built by Claude (Fable 5) from the public datasets above. Educational only — verify against primary sources before acting.
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 →Nothing here is signaling trouble: several manufacturers, no current shortage, no recent serious recalls, stable pricing. In drug supply, boring is the good outcome.
The score counts pressure that is already visible — fewer makers, shortages, recalls, falling prices. 0 means none of it; 100 means all of it at once. Recomputed daily · as of Sep 3, 2026
