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 30 capsules? Is it lower than what I would pay through my insurance?
- 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 RIFAMPIN 150 MG CAPSULE 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 Rifampin* / Rifampin: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's EA. Joined on generic name. *: CMS says this average reflects multiple routes of administration, which may have different unit prices. All 14 NADAC NDCs the name join matched to it have an FDA route including ORAL. 2 of the 14 NDCs that point at this name are not listed in the FDA NDC Directory as packages of their own; their route was taken from FDA's record for the same product (labeler and product code).
