What Medicare paid

Medicare Part D paid $9.20 for 1 unit (EA), at an average of $9.20287 per EA in 2024 (2024-01-01 to 2024-12-31) for “Lamotrigine ODT (Orange)” and “Lamotrigine”, every strength and form sold under that name together (Medicare Part D Spending by Drug, file of 2026-06-25).

That average covers 86 Part D claims (fills, including refills) for 2024-01-01 to 2024-12-31, across every maker, strength and form under the name.

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.

Questions

Why is the comparison with Medicare for LAMOTRIGINE ODT KIT (ORANGE) 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 Lamotrigine ODT (Orange) / Lamotrigine: 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.
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.
