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 unit (EA)? 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 RISPERDAL CONSTA 50 MG VIAL 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 Risperdal Consta / Risperidone Microspheres: 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 1 unit (EA)?
- NADAC prices this product per EA, and the FDA NDC Directory lists its NDC as dosage form “KIT” with no route. Only a tablet, capsule, lozenge or troche with route “ORAL”, or a tablet or film with route “SUBLINGUAL” or “BUCCAL”, starts at 30, and this is not one. NADAC’s EA for it may be the whole kit or one item in it, and the files do not say which. So the card starts at 1 unit (EA) rather than guess how many make up a fill; change it to match your prescription.
