How to Save Money on Humulin N in 2026: Coupons, Discounts, and Patient Assistance

The cost of insulin has long been a serious concern for people with diabetes. The good news in 2026: Humulin N is significantly more affordable than it was just a few years ago, and there are multiple programs that can reduce your out-of-pocket cost to as little as $35 a month — or even zero if you qualify.

Here's a complete breakdown of every way to save on Humulin N in 2026.

How Much Does Humulin N Cost Without Insurance?

Since Eli Lilly cut its most commonly prescribed insulin prices by 70% starting in Q4 2023, Humulin N retail list prices dropped dramatically. The approximate retail prices are:

Humulin N 10 mL vial (100 units/mL): Approximately $82-$86 retail list price

Humulin N KwikPen (5-pack, 3 mL each): Approximately $92 retail list price

These prices are a 70% reduction from pre-2023 pricing. But with the programs below, you can reduce your cost even further.

Option 1: Lilly Insulin Value Program — $35/Month Cap

The Lilly Insulin Value Program caps your monthly out-of-pocket cost for Humulin N at $35 — whether you have commercial insurance or no insurance at all. This is the most straightforward way to reduce your cost.

Eligibility: Commercially insured patients or uninsured patients paying cash

How to get it: Download a savings card at insulinaffordability.com. At approximately 85% of U.S. retail pharmacies, the discount may apply automatically for commercially insured patients — no card needed.

Phone: 1-833-808-1234

No annual limit on vials/pens: There is no cap on how many vials or pens can be covered each month, as long as they are prescribed. There is a $16,000 annual coverage limit.

Option 2: Lilly Cares Foundation — Patient Assistance Program (PAP)

For patients who are uninsured and have limited income, Lilly offers the Lilly Cares Foundation program, through which you may qualify to receive Humulin N at no cost.

Eligibility: Uninsured patients with limited income. Authorization is effective for one year and can be renewed.

How to apply: Ask your doctor to help complete the application from lillycares.com. Applications can be submitted by mail or fax.

Phone: 1-800-545-6962

Option 3: Walmart ReliOn NPH — OTC at $25 Per Vial

Walmart sells NPH insulin under the ReliOn brand at approximately $25 per 10 mL vial (100 units/mL) without a prescription. This is the same drug class as Humulin N. If you use one vial per month, ReliOn NPH at Walmart may be your lowest-cost option — no insurance, no coupon, no prior authorization required.

Always consult your doctor before switching between insulin brands, even within the same class.

Option 4: GoodRx and Other Discount Cards

GoodRx and similar discount programs (SingleCare, RxSaver, Blink Health) negotiate discounts on brand-name and generic drugs at participating pharmacies. For Humulin N, GoodRx discounts may bring the price down to approximately $35-$50 per month depending on your pharmacy and location.

GoodRx coupons can typically be used in place of insurance — you present the coupon at the pharmacy counter. However, note that you generally cannot use GoodRx simultaneously with insurance. Compare prices to see which option saves you more.

Option 5: Medicare Coverage

Humulin N is covered by most Medicare Part D plans. The Inflation Reduction Act, which took effect in 2023 and was phased in through 2024-2025, capped monthly insulin costs at $35 for Medicare Part D enrollees. If you are on Medicare and paying more than $35/month for Humulin N, contact your plan or pharmacist to make sure you are receiving the capped price.

Option 6: State Programs and Non-Profit Assistance

Several states have their own insulin affordability programs. For example, Minnesota has an Insulin Safety Net program that provides emergency insulin supplies at no cost for qualifying patients. Visit NeedyMeds.org or RxAssist.org to search for programs available in your state.

Summary: Your Cheapest Options for Humulin N in 2026

Uninsured, limited income: Apply for Lilly Cares Foundation (potentially free) or Lilly Diabetes Solution Center ($35/month cap)

Uninsured, any income: Lilly Insulin Value Program savings card ($35/month) or Walmart ReliOn NPH (~$25/vial)

Commercially insured: Lilly Insulin Value Program ($35/month cap, often automatic at participating pharmacies)

Medicare: $35/month cap under the Inflation Reduction Act's insulin provisions

Bottom Line

There is no reason to pay full list price for Humulin N in 2026. Between Lilly's Insulin Value Program ($35 cap), Walmart's ReliOn NPH (~$25/vial), and the Medicare $35 cap, virtually every patient can find a path to affordable insulin.
