Why is the comparison with Medicare for ODACTRA 12 SQ-HDM SL TABLET 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 Odactra / Mite,D.Farinae-D.Pteronyssinus: 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 brand name.

Why does this page start at 30 tablets?

NADAC prices this product per EA, and the FDA NDC Directory lists 1 of its 2 NDCs (it does not list the other one) as a tablet taken under the tongue (dosage form “TABLET”, route “SUBLINGUAL”), so one EA is one tablet. OpenBill counts a tablet or film taken under the tongue or against the cheek as an oral solid, like one that is swallowed. The card starts at 30 tablets, a common one-month supply of a once-a-day medicine; change it to match your prescription.

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 tablets? 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.
