Januvia costs $600–$700/month without insurance. Here are the best coupons, discount cards, savings programs, and patient assistance options to lower your Januvia cost in 2026.

Januvia (sitagliptin) is one of the most effective oral medications for type 2 diabetes, but it comes with a steep price tag. The average retail price for a 30-day supply of Januvia 100 mg is $600–$700 — and with no true generic equivalent yet widely available, that cost falls on patients who don't have adequate insurance coverage.

The good news is there are multiple real ways to reduce what you pay for Januvia — from manufacturer programs to discount cards to pharmacy-specific savings. Here's what's actually available in 2026.

Option 1: Merck Copay Savings Card — Best for Commercially Insured Patients

Merck offers a savings card for Januvia that can reduce your out-of-pocket cost to as little as $5 per prescription fill. The card provides savings of up to $150 per qualifying prescription for up to a 90-day supply.

Key details:

Who qualifies: Patients with commercial (private) health insurance. NOT valid for Medicare, Medicaid, Tricare, VA, or other government insurance programs.

Savings limit: Up to $150 per prescription fill; patient must pay a minimum of $5.

Frequency: Card can be used once every 30 days.

Can't be combined: Cannot be used with GoodRx/SingleCare or other discount cards simultaneously.

Where to get it: januvia.com or ask your doctor's office for a printed coupon.

Option 2: Merck Patient Assistance Program — Best for Uninsured/Low-Income Patients

The Merck Patient Assistance Program (PAP) provides Januvia free of charge to eligible patients. This program is specifically designed for patients who are uninsured, underinsured, or face financial hardship despite having insurance.

Eligibility: Based on income and insurance status. Merck reviews applications individually.

Duration: Free medication for up to 1 year; patients can reapply if still in need.

How to apply: Visit merckhelps.com or call 1-800-727-5400. Your doctor will need to complete a portion of the application.

Option 3: GoodRx Coupons — Good for Uninsured or High-Copay Patients

GoodRx offers discount coupons for Januvia and for the generic sitagliptin (Zituvio/authorized generic). With a GoodRx coupon at participating pharmacies:

Brand Januvia: Prices vary by pharmacy but GoodRx can reduce the cost significantly vs. retail — compare prices at goodrx.com/januvia.

Generic sitagliptin (Zituvio/authorized generic): As low as $110/month with GoodRx at select pharmacies.

GoodRx can be used with or without insurance but cannot be combined with the Merck savings card. Always compare the GoodRx price against your insurance copay to see which is lower.

Option 4: SingleCare Discount Card

SingleCare offers a free discount card that can reduce the price of Januvia to approximately $285–$286 for 30 tablets of 100 mg at participating pharmacies. Like GoodRx, SingleCare is free to use and works at most major pharmacy chains. It's worth comparing both GoodRx and SingleCare prices for your specific pharmacy, as prices can vary.

Option 5: Ask Your Doctor About Zituvio

Zituvio (sitagliptin free base, Zydus Pharmaceuticals) was FDA-approved in October 2023. It contains the same active ingredient as Januvia but cannot be automatically substituted. Your doctor must write a new prescription for Zituvio. At certain specialty pharmacies like Marley Drug, Zituvio (as an authorized generic sitagliptin) is available for approximately $80/month — substantially cheaper than brand-name Januvia.

Option 6: Mail-Order Pharmacy for 90-Day Supplies

If you have insurance coverage for Januvia, switching to your plan's mail-order pharmacy often provides a 90-day supply at a lower per-day cost compared to filling 30 days at a retail pharmacy. Most employer-sponsored plans have a mail-order option — contact your insurance company or HR department to find out which service is in-network.

Option 7: Generic Sitagliptin Expected in 2026

The most significant cost relief on the horizon is the anticipated entry of true generic sitagliptin phosphate into the U.S. market. Merck's key patent expires November 24, 2026, and settlement agreements may allow generic manufacturers to enter as early as May 2026. Once widely available, generic sitagliptin is expected to cost approximately $50–$100 per month — an 80–85% reduction from current brand-name pricing.

Savings Summary: What's Available Right Now

Merck Savings Card: As low as $5/fill — for commercially insured patients only

Merck Patient Assistance Program: Free Januvia — for uninsured/low-income patients

GoodRx coupon (Januvia): Significant discount vs. retail; compare at goodrx.com

GoodRx coupon (generic sitagliptin/Zituvio): ~$110/month at select pharmacies

SingleCare: ~$285/month for brand Januvia at participating pharmacies

Zituvio Rx (at Marley Drug): ~$80/month — same active ingredient, requires new prescription

No. GoodRx and SingleCare discount cards cannot be combined with insurance in most cases. You must choose one or the other at the point of sale. Ask your pharmacist to run the price through both your insurance and a GoodRx coupon to see which gives you the lower price — sometimes the discount card beats your insurance copay.
