Frequently Asked Questions

Januvia (Sitagliptin) costs an average of $219.00 per claim based on Medicare Part D data. The estimated annual cost per patient is $1,753.00. Actual out-of-pocket costs depend on your insurance plan and pharmacy.

Januvia averages $219.00 per Medicare Part D claim — roughly equivalent to a 30-day supply for most patients on standard dosing. Without insurance, expect higher cash-pay prices unless you use a discount program (GoodRx, SingleCare, manufacturer copay assistance). With Medicare or commercial insurance, your out-of-pocket cost depends on your plan's formulary tier and deductible status.

A typical 30-day supply of Januvia reflects in our Medicare Part D average of $219.00 per claim. No generic is available yet, so cost remains at brand-name pricing. Cash-pay prices vary by pharmacy — comparison shopping (or using GoodRx coupons) often saves 20-50% off the listed price.

Most commercial insurance plans and Medicare Part D plans cover Januvia, but coverage varies by formulary tier. Januvia is often Tier 2 or Tier 3 on most formularies, meaning a higher copay than generic alternatives. Some plans require prior authorization or step therapy. Check your plan's formulary or call the number on your insurance card to confirm.

Several options for cash-pay patients: (1) Manufacturer patient assistance programs — the manufacturer may offer copay cards or free-drug programs for income-qualified patients; (2) Discount programs like GoodRx, SingleCare, or RxSaver typically save 20-80% off the cash price; (3) Mark Cuban's Cost Plus Drugs offers transparent generic pricing if a generic is available; (4) 340B-eligible community health centers offer drugs at federally negotiated discounts. Patient assistance programs are the primary affordability path while no generic is available.

Januvia is still under patent protection until Jul 17, 2026, giving the manufacturer market exclusivity. Once the patent expires, generics enter the market and prices typically fall 80-95% within 1-2 years.

No, Januvia is currently brand-only. Patent protection expires Jul 17, 2026, after which generic versions may enter the market.

Medicare Part D spent $2.7B on Januvia, covering 1,560,000 beneficiaries across 12,480,000 claims. This makes it one of the tracked drugs in the Medicare spending dashboard.

Check manufacturer patient assistance programs for potential savings. You can also compare prices at different pharmacies, use prescription discount programs (GoodRx, SingleCare, Cost Plus Drugs), or ask your doctor about therapeutic alternatives in the same drug class.

this entity is one of the data points covered by this site’s U.S. Medicare prescription-drug pricing dataset. The detail above comes directly from CMS Medicare Part D Drug Spending data; the context that follows situates the headline numbers against the broader distribution across U.S. prescription drugs.

Every number on this page links back to CMS Medicare Part D Drug Spending data; the methodology page describes the inputs, refresh cadence, and known limitations of the underlying data product.

Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for this entity’s peers within U.S. prescription drugs. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.

Cost data reflects Medicare Part D spending and may not represent retail pharmacy prices. Average cost per claim represents the total drug cost (not patient out-of-pocket) divided by total claims.
