What Your Prescriptions Cost
How much does Farxiga cost with Medicare in 2026?
Last reviewed: · Big Sioux Benefits Data Desk
Farxiga has a Medicare-negotiated price of $178.50 for a 30-day supply as of January 1, 2026, down from a list price of $556, a 68% reduction (CMS, Negotiated Prices for Initial Price Applicability Year 2026). About 994,000 Medicare beneficiaries used it in 2023, accounting for $4.3 billion in Part D gross covered drug costs.
The qualifier: Farxiga is prescribed across three conditions, type 2 diabetes, heart failure, and chronic kidney disease, and it sits in the same drug class as Jardiance, which was also selected for negotiation. Their negotiated prices differ, $178.50 against $197, but that gap is small enough that your plan's tier placement will usually matter more than the underlying price difference.
What a year on Farxiga looks like
| Step | Illustration under the standard 2026 benefit |
|---|---|
| Drug cost for the year at the negotiated price | About $2,142 |
| You pay during the deductible | Up to $615 |
| You pay after the deductible | 25% of the remaining cost, about $382 |
| Approximate out-of-pocket for the year | About $997, under the $2,100 cap |
How this illustration is built: the 2026 standard Part D benefit, meaning a full $615 deductible, then 25% coinsurance, then $0 once your out-of-pocket total reaches $2,100. Your plan may use copays instead of coinsurance, may charge a smaller deductible or none, and may place the drug on a different tier, so treat this as the shape of the year rather than a quote. We are not showing plan-specific copays because we will not publish a number we cannot source.
People taking Farxiga frequently take other cardiac or diabetes drugs alongside it, and that combination is what determines whether the annual cap comes into play. If you take three or more brand-name maintenance drugs, work the total rather than each drug separately, using when you hit the $2,100 cap.

Farxiga or Jardiance, which is cheaper under Medicare in 2026?
By negotiated price, Farxiga is slightly cheaper at $178.50 for a 30-day supply against Jardiance's $197. In practice the difference to you depends on your plan's tier placement for each, which can easily outweigh an $18.50 gap in the underlying price. This is a prescriber conversation, not a substitution you make on your own.
Does Medicare cover Farxiga for chronic kidney disease?
Coverage for a specific use is set by your plan's formulary and any prior authorization rules attached to the drug, not by the negotiation program. The negotiated price applies whenever the drug is covered. If your plan requires prior authorization for a particular indication, your prescriber submits the clinical justification.
