Bulk ingredient — not a finished product
This NDC is a raw material (bulk ingredient for human prescription compounding) sold to drug manufacturers or compounders, not a product pharmacies dispense. Retail pricing, TE codes, fragility scores, and shortage reports don't apply to bulk listings — those attach to finished products made from this ingredient.
Medicare Part D
This is a bulk ingredient, not a dispensable product — it is a raw material sold to manufacturers and compounders, so no plan prices it.
How Part D pricing works →NADAC price per unit
No NADAC pricing on file for this NDC — NADAC covers drugs dispensed by retail community pharmacies.
