How to Save Money on Insulin, Human Isophane (NPH) in 2026: Coupons, Discounts, and Patient Assistance

If you take NPH insulin — Humulin N or Novolin N — you know that the retail price can be shocking: up to $158 per 10 mL vial without insurance. But there are multiple programs that can dramatically reduce that cost — and in some cases, bring it down to $0. Here is a complete guide to saving money on insulin, human isophane in 2026.

Option 1: Walmart ReliOn Novolin N — The Cheapest Option at ~$25/Vial OTC

This is the most affordable option available — period. Walmart sells Novolin N under the ReliOn brand for approximately $25 per 10 mL vial (100 units/mL), and it is available without a prescription in most states. Just walk up to the pharmacy counter and ask.

ReliOn Novolin N is exactly the same medication as Novolin N — same active ingredient (insulin isophane human), same concentration (100 units/mL), just under Walmart's private label. Important note: even though no prescription is needed to buy it, you should use it under your doctor's guidance for safe and appropriate dosing.

Option 2: Manufacturer Savings Programs — $35/Month Caps

Both major NPH insulin manufacturers offer savings programs that cap your out-of-pocket cost at $35/month:

• Lilly Insulin Value Program (Humulin N): Pay no more than $35/month regardless of how many vials or pens you use. No income requirement. Works for commercially insured and uninsured patients. Register at insulinaffordability.com or call 1-833-808-1234.
• Novo Nordisk My Insulin Rx (Novolin N): Cap your cost at $35 for up to 3 vials, 2 packs of pens, or any combination up to 35 mL. No insurance required. Register at novocare.com/myinsulinrx or call 1-888-910-0632.

Option 3: Medicare Patients — $35/Month Federal Cap

If you have Medicare, the Inflation Reduction Act permanently capped your monthly out-of-pocket cost for insulin at $35/month as of January 2024. This applies regardless of which Medicare Part D plan you are on and covers any covered insulin product, including Humulin N and Novolin N. If you are currently paying more than $35/month for NPH insulin on Medicare, contact your plan or pharmacist immediately — you may be overpaying.

Option 4: GoodRx and Discount Cards

GoodRx coupons can reduce the retail price of Humulin N to approximately $47-50 per vial at participating pharmacies. SingleCare offers similar savings — bringing Novolin N down from approximately $148 to around $46 per vial. These are good options if you are uninsured and cannot access the Walmart or manufacturer savings programs.

Note: You generally cannot use GoodRx and your insurance at the same time. Compare your insurance copay against the GoodRx price and use whichever is lower.

Option 5: Patient Assistance Programs (Free Insulin)

If you are uninsured and have a limited income, you may qualify to receive NPH insulin at no cost through manufacturer patient assistance programs (PAPs):

• Lilly Cares Foundation (Humulin N): Provides insulin at no cost for uninsured patients with limited income. Eligibility is income-based; authorization lasts one year and is renewable. Apply at lillycares.com or ask your doctor to submit on your behalf.
• Novo Nordisk Patient Assistance Program (Novolin N): Free insulin for most people without insurance with limited incomes. Requires valid prescription and proof of income. Call 1-866-310-7549 or visit novocare.com/psp/PAP.html.

Option 6: State Insulin Affordability Programs

More than 20 states have their own insulin affordability laws with copay caps ranging from $25 to $100 per month. For example, Minnesota has an Insulin Safety Net program that provides emergency insulin supplies. Visit NeedyMeds.org or RxAssist.org to find programs in your state.
