What to ask at the counter
None of these figures is your price: what you pay depends on your pharmacy, your insurance, coupons and discounts.
- What is your cash price for 1 mL? Is it lower than what I would pay through my insurance?
- Which NDC (the 11-digit number on the package) is this? Pharmacies pay $4.20713 to $8.85194 per ML for this product, depending on the NDC.
- How much is in the package I am getting? This page uses 1 mL; your package may hold a different amount.
- If you have Medicare Part D: what is my plan’s copay or coinsurance for it? The Part D average on this page is not what you pay.
- These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
Questions
- Why is the comparison with Medicare for BIMATOPROST 0.03% 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 Bimatoprost* / Bimatoprost: 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. *: CMS says this average reflects multiple routes of administration, which may have different unit prices. All 26 NADAC NDCs the name join matched to it have an FDA route including OPHTHALMIC.
- Why does this page start at 1 mL?
- The FDA package descriptions of this product’s NDCs give different amounts (2.5 mL, 5 mL, 7.5 mL). So the card starts at 1 ML; change it to match your prescription.
