Beyond what the card shows, the records give these reasons: The Part D figure covers 2024-01-01 to 2024-12-31; the NADAC price is from the file of 2026-10-14. Part D spending basis, as the Part D record states it: Part D 2024 average spend per dosage unit for Toujeo Solostar / Insulin Glargine,Hum.Rec.Anlog: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's ML. Joined on brand name.
Why does this page start at 4.5 mL?
NADAC prices this product per ML. The FDA NDC Directory’s package description gives 4.5 mL in one package for this product’s NDC (“3 SYRINGE in 1 CARTON (0024-5869-03) / 1.5 mL in 1 SYRINGE (0024-5869-01)”), so the card starts at one package: 4.5 ML. Change it to match your prescription.
