Janumet cost with Medicare

In 2026, a Medicare drug plan (Part D) can charge a deductible of up to $615, and once you've spent $2,100 out of pocket on covered drugs, you pay nothing more for covered drugs that year ($2,400 in 2027) (Medicare.gov). What you pay for Janumet depends on your plan's drug list and your coverage phase. Starting January 1, 2027, Medicare will pay a negotiated price of $80 for a 30-day supply of Janumet and Janumet XR (CMS, checked Oct 30, 2026). That's what Medicare will pay, not your copay. If your income is limited, Extra Help lowers drug costs: in 2026 you pay no more than $5.10 for a generic and $12.65 for a brand-name drug, with income under $23,940 ($32,460 for a married couple) and resources under $18,090 ($36,100 for a couple) (CMS). The free Medicare Prescription Payment Plan spreads costs into monthly payments, but it doesn't lower the total.

Janumet cost with insurance

With private or employer insurance, what you pay for Janumet depends on your plan's drug list, deductible and copay. Your copay depends on your plan. You may also choose Merck's $84.57 cash price instead of using your insurance; Merck's terms say it is not applied to your insurance deductible (Merck).

Medicaid: Your state Medicaid program sets any copay. Ask your pharmacist or state Medicaid office (Medicaid.gov).

What is Janumet used for?

Janumet combines sitagliptin, a DPP-4 inhibitor, with metformin. According to its FDA label (DailyMed), it is used:

• Along with diet and exercise, to improve blood sugar control in adults with type 2 diabetes.

Janumet comes as 50/500 mg and 50/1000 mg tablets (sitagliptin/metformin), taken twice a day with meals. Its label has a boxed warning about lactic acidosis, a rare but serious buildup of acid in the blood linked to metformin; the risk is higher with kidney problems, older age and some other conditions. It is not for type 1 diabetes and has not been studied in people with a history of pancreatitis. Your prescriber decides which medicine is right for you.
