Questions

Why is the comparison with Medicare for DORZOLAMIDE HCL 2% EYE DROPS labelled estimated?
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 Dorzolamide HCl / Dorzolamide HCl: 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 generic name.
Why does this page start at 10 mL?
NADAC prices this product per ML. The FDA NDC Directory’s package description gives 10 mL in one package for the 10 of this product’s 11 NDCs it lists (“1 BOTTLE, DROPPER in 1 CARTON (24208-485-10) / 10 mL in 1 BOTTLE, DROPPER”), so the card starts at one package: 10 ML. Change it to match your prescription.
