Humalog (insulin lispro) is Eli Lilly's fast-acting mealtime insulin, used to control blood sugar spikes around eating rather than providing all-day baseline coverage the way a long-acting insulin does. It's one of the most widely prescribed insulins in the country, which also makes it one of the most searched when people lose coverage or switch jobs.
The pricing story here is a little different from most brand-name drugs, because Lilly cut Humalog's list price by 70% back in 2023 and simultaneously launched an authorized generic at $25 a vial. That means the "real" cost of Humalog today depends heavily on which version you ask for and which savings program you use — the gap between the worst-case price and the best-case price is enormous.
This guide breaks down exactly what Humalog costs at every stage, how it compares to the generic and to competing insulins, and how to apply for the savings card or the free Patient Assistance Program without losing weeks to paperwork problems.

What Humalog Actually Costs Without Insurance
Humalog is dispensed in a few different forms — vials, cartridges, standard KwikPens, and the higher-concentration U-200 KwikPen. Cash pricing depends on which form your prescription specifies.
| Form | Typical Cash Price (No Discount) | Typical Discount-Card Price |
|---|---|---|
| 10 mL Vial (U-100) | $72–$86 | $55–$70 |
| Box of 5 KwikPens (15 mL) | $150–$165 | $90–$135 |
| U-200 KwikPen (6 mL) | $125–$135 | $80–$100 |
| With Lilly $35 Savings Card | $35 per 30-day fill, regardless of form or quantity needed | |
| Lilly Cares Patient Assistance | $0 if income-eligible | |
Why "list price" and "cash price" don't match: Lilly's 2023 cut lowered the wholesale acquisition cost of Humalog vials by 70%, but retail cash prices at the pharmacy counter still include the pharmacy's own dispensing markup. That's why a vial can list around $72–$86 at wholesale while some pharmacies still quote closer to $100 in cash before any discount card is applied.
Humalog vs. Generic Insulin Lispro: Price Comparison
This is the single most useful comparison in this entire guide. In 2023, Lilly launched an authorized generic of Humalog — same manufacturer, same molecule, same manufacturing line — sold under the name "insulin lispro injection 100 units/mL."
| Product | Active Ingredient | 10 mL Vial List Price | Manufacturer |
|---|---|---|---|
| Humalog (brand) | Insulin lispro | $72–$86 | Eli Lilly |
| Insulin Lispro (authorized generic) | Insulin lispro | $25 | Eli Lilly |
Ask for it by name: To get the generic price, your prescriber needs to write the prescription as "insulin lispro injection 100 units/mL" rather than "Humalog." Most pharmacies stock both, and pharmacists can sometimes substitute automatically — but it's worth confirming before you pay.
Humalog vs. Other Rapid-Acting Insulins
Humalog isn't the only mealtime insulin on the market. Here's how it stacks up against the other major rapid-acting options patients commonly compare it to.
| Insulin | Manufacturer | Typical Cash Price (Box) | Manufacturer $35 Program? |
|---|---|---|---|
| Humalog | Eli Lilly | $150–$165 | Yes — Insulin Value Program |
| Insulin Lispro (generic) | Eli Lilly | $25–$45 per vial | Yes — Insulin Value Program |
| Lyumjev | Eli Lilly | $150–$165 | Yes — Insulin Value Program |
| Novolog | Novo Nordisk | $450–$550+ | Yes — NovoCare $35 program |
| Fiasp | Novo Nordisk | $450–$550+ | Yes — NovoCare $35 program |
| Admelog | Sanofi | $140–$160 | Discount cards only |
Both Lilly and Novo Nordisk offer $35 manufacturer programs, so the actual out-of-pocket cost between Humalog and Novolog can end up identical once a savings card is applied — even though their list prices look completely different on paper.
The $35 Lilly Insulin Value Program
This is the fastest, easiest way to bring Humalog's cost down, and it's the option most patients should try first.
| Feature | Details |
|---|---|
| Monthly Cost | $35 for a 30-day supply, regardless of vials or pens needed |
| Who Qualifies | Patients with commercial insurance or no insurance at all |
| Income Check? | No — no income documentation required |
| Excluded Groups | Medicare, Medicaid, TRICARE, and VA beneficiaries cannot use this card |
| Products Covered | Humalog U-100, Humalog Mix 75/25, Humalog Mix 50/50, generic insulin lispro, Lyumjev, Humulin, Basaglar |
| How to Get It | Download the card at insulins.lilly.com or call 1-833-808-1234 |
One card, two versions: Lilly runs a slightly different offer for commercially insured patients versus cash-paying uninsured patients, but both land at the same $35 price point. You don't need to know which applies to you — the pharmacist selects the right one once the card is on file.
Because there's no income requirement, this card is worth trying even if you assume you make too much to qualify for other assistance. It covers every insulin in Lilly's current lineup, so a household managing more than one insulin type can use it across multiple prescriptions.
The Lilly Cares Patient Assistance Program (Free Humalog)
If $35 a month is still out of reach, the Lilly Cares Foundation Patient Assistance Program (PAP) is a separate, income-based charity program that can provide Humalog at no cost at all. Unlike the savings card, this program requires documentation and takes longer to process.
| Feature | Details |
|---|---|
| Cost to Patient | $0 for approved medication |
| Who Qualifies | Uninsured patients, or those enrolled in Medicare Part D |
| Income Limit for Humalog | At or below 400% of the Federal Poverty Level (Group 2 medication) |
| Documentation Needed | Proof of income, insurance status, and a completed prescriber section |
| Enrollment Length | 12 months for uninsured patients; through the end of the calendar year for Medicare Part D patients |
| Delivery | Shipped to your home or your provider's office, depending on setup |
Who typically doesn't qualify: Patients with Medicaid or VA prescription benefits are generally not eligible for Lilly Cares, since those programs are considered adequate existing coverage. Patients with commercial insurance that already covers Humalog are usually directed to the $35 savings card instead.
Eligibility Comparison: Savings Card vs. Patient Assistance Program
| Situation | $35 Savings Card | Free Patient Assistance Program |
|---|---|---|
| No insurance, any income level | Eligible | Eligible only if income ≤ 400% FPL |
| Commercial insurance covering Humalog | Eligible | Not eligible |
| Medicare Part D | Not eligible for the card | Eligible if income ≤ 400% FPL |
| Medicaid | Not eligible | Generally not eligible |
| Household income above 400% FPL, no insurance | Eligible | Not eligible |
Income Limit Comparison (2026 FPL Guidelines)
Lilly Cares sorts its medications into groups, each tied to a different percentage of the Federal Poverty Level (FPL). Humalog falls into Group 2, capped at 400% FPL — the same tier as Basaglar, Humulin, and Lyumjev. Here's how that compares to Lilly Cares' other tiers for the 48 contiguous states (Alaska and Hawaii use higher figures — call for exact numbers).
| Household Size | Group 1 — 300% FPL | Group 2 (Humalog) — 400% FPL | Group 3/4 — 500% FPL |
|---|---|---|---|
| 1 Person | ~$47,880 | ~$63,840 | ~$79,800 |
| 2 People | ~$65,040 | ~$86,720 | ~$108,400 |
| 3 People | ~$82,200 | ~$109,600 | ~$137,000 |
| 4 People | ~$99,360 | ~$132,480 | ~$165,600 |
Higher limits apply in Alaska and Hawaii. If your household has more than four people, or you live in either of those states, call Lilly Cares directly at 1-800-545-6962 rather than estimating from this table.
Covered Medications Comparison
It helps to see where Humalog sits relative to other Lilly products, since some patients managing diabetes are also on a long-acting insulin or a GLP-1 medication that falls into a different income group.
| Program | Humalog Status | Other Lilly Insulins Included | Income Check Required? |
|---|---|---|---|
| Insulin Value Program ($35 card) | Covered | Generic insulin lispro, Lyumjev, Humulin, Basaglar | No |
| Lilly Cares PAP (Group 2) | Covered — free if eligible | Lyumjev, Humulin, Basaglar | Yes — 400% FPL |
| Lilly Cares PAP (Group 1) | Not in this group | Trulicity, Cialis, Emgality, Forteo | Yes — 300% FPL |
| Medicare Part D Insulin Cap | Covered | Any covered insulin on your plan's formulary | No — automatic |

Real-World Cost Examples
Example 1: Uninsured, using two KwikPen boxes a year
Maria is uninsured and uses one Humalog KwikPen box (5 pens) roughly every two months. Without any discount, that's about $150–$165 every other month, or roughly $900–$1,000 a year.
With the $35 Insulin Value Program card, each fill drops to $35. Annual cost: about $210 instead of $900–$1,000.
Example 2: Switching to generic insulin lispro
James uses one 10 mL vial a month and doesn't want to deal with a savings card. His prescriber rewrites the prescription as "insulin lispro injection 100 units/mL" instead of Humalog.
List price drops from $72–$86 per vial to $25 per vial. Annual savings: roughly $560–$730 with no enrollment required.
Example 3: Low-income, uninsured, applying to Lilly Cares
Denise is uninsured, supports a household of two, and earns $38,000 a year — well under the ~$86,720 Group 2 limit for a two-person household. She applies to Lilly Cares with her prescriber's help.
Once approved, Humalog ships to her at no cost for a 12-month enrollment period. Annual cost: $0, instead of roughly $900–$1,000 at cash price.
How to Apply, Step by Step
Applying for the $35 Savings Card
Download the card
Visit insulins.lilly.com or call 1-833-808-1234 to get the Lilly Insulin Value savings card, either as a printable PDF or a digital version for your phone.
Bring it to any pharmacy
Present the card along with your Humalog prescription. No enrollment form or income proof is needed.
Confirm the price before you pay
Ask the pharmacist to run the card and confirm you're being charged $35, not a partial discount, before completing the transaction.
Applying for the Lilly Cares Patient Assistance Program
Get the application
Download the Lilly Cares application at lillycares.com or call 1-800-545-6962 to have one mailed or faxed to you.
Complete the patient section
Fill in household size, income, and current insurance status accurately — mismatches here are the most common reason applications stall.
Have your prescriber complete their section
Your doctor confirms the diagnosis, medication, dose, and signs the form. Bringing the form to your next appointment saves a separate office visit.
Attach proof of income
A recent tax return, pay stub, or Social Security benefits statement usually satisfies this requirement.
Submit by fax or mail
Send the completed application to Lilly Cares Foundation, PO Box 13185, La Jolla, CA 92039, or fax to 1-844-431-6650.
Wait for written notification
Both you and your prescriber will receive a letter confirming approval or denial, along with delivery instructions if approved.
Decision Tree: Which Option Fits You
Step 1: Do you have Medicare, Medicaid, or VA benefits?
This determines which savings tool you can even use.
Check your plan's insulin cap
Medicare Part D and Medicare Advantage already cap insulin at $35/month by law.
Income ≤ 400% FPL?
If yes, Lilly Cares PAP can make Humalog fully free instead.
Ask about generic insulin lispro first
Same drug, $25 vial list price, no card needed.
Need the pen, or still can't afford it?
Try the $35 savings card, then Lilly Cares PAP if income ≤ 400% FPL.
Approval Timelines
| Program | Typical Timeline |
|---|---|
| $35 Savings Card | Immediate — applied at time of purchase |
| Generic Insulin Lispro Switch | Immediate — same-day with a rewritten prescription |
| Lilly Cares PAP (complete application) | 1–3 weeks |
| Lilly Cares PAP (missing documents) | Delayed until resubmitted, often adding 2+ weeks |
| Medicare insulin cap | Automatic — no application needed |
Renewing Your Enrollment
- The $35 savings card typically expires December 31 each year — download the updated card early in the new year to avoid a gap.
- Lilly Cares enrollment runs 12 months for uninsured patients, or through the calendar year for Medicare Part D patients, after which reapplication is required.
- Submit renewal paperwork a few weeks before your current enrollment ends, since processing isn't instant.
- Report any change in insurance or income right away — gaining new coverage can end PAP eligibility mid-cycle.

Bottom Line
Humalog's cash price without insurance — $150 to $165 for a standard box, or $72 to $86 for a vial — is almost never what patients actually end up paying. The authorized generic drops that to $25 a vial with no enrollment at all. The $35 Lilly Insulin Value Program covers nearly everyone with commercial insurance or no insurance, with no income documentation required. For patients who need it, the Lilly Cares Foundation Patient Assistance Program can bring the cost to zero, provided household income falls at or below 400% of the federal poverty level.
The step that actually determines your out-of-pocket cost isn't finding a program — it's confirming which one applies to your specific insurance status before you pay full price at the register.

A standard box of five 3 mL Humalog KwikPens (15 mL total) typically costs $150 to $165 in cash without insurance, while a 10 mL vial runs roughly $72 to $86 following Eli Lilly's 2023 price cut. Most patients don't pay this, since Lilly's Insulin Value Program caps a 30-day supply at $35 for insured and uninsured patients alike.
Yes. Eli Lilly sells an authorized generic called insulin lispro injection 100 units/mL that is chemically identical to Humalog. A 10 mL vial of the generic lists at $25, compared to $72 to $86 for a branded Humalog vial, and pharmacies fill it the same way once your prescriber writes it by that name.
Yes. The Lilly Insulin Value Program caps Humalog, Humalog Mix formulations, and generic insulin lispro at $35 for a 30-day supply for both commercially insured and cash-paying uninsured patients, with no income documentation required. It does not apply to Medicare, Medicaid, or VA beneficiaries.
Uninsured patients or those on Medicare Part D whose household income falls at or below 400% of the federal poverty level can typically get Humalog at no cost through the Lilly Cares Foundation Patient Assistance Program. The application requires a prescriber signature and proof of income.
Most Medicare Part D and Medicare Advantage drug plans cover Humalog, and under current federal law, out-of-pocket costs for covered insulins are capped at $35 for a month's supply, regardless of your plan's deductible. Coverage still varies by plan, so it's worth checking your specific formulary. See our Medicare Part D insulin coverage guide for details.
They are the same medication made by the same manufacturer, Eli Lilly, with identical active ingredients and performance. The only difference is the name on the label and the price — the generic almost always costs less when paying cash.
The savings card is a $35 discount available to almost anyone with a prescription, insured or not, with no income check. The Patient Assistance Program is an income-based charity program that provides Humalog completely free, but requires proof of income and a completed prescriber section, and takes longer to process.
You likely won't qualify for the Lilly Cares Patient Assistance Program, but you can still use the $35 savings card regardless of income, since that program has no income requirement at all.
No. These are separate programs designed for different situations — the savings card reduces a cash or copay price, while the PAP replaces that price entirely with free medication. You'd use one or the other based on your income and insurance status, not both at once.
Usually yes. Your prescriber needs to write or amend the prescription to specify "insulin lispro" rather than "Humalog" so the pharmacy dispenses the generic version and bills it at the generic price.
Report the change to Lilly Cares as soon as it happens. Gaining insurance that adequately covers Humalog can end your PAP eligibility before your 12-month enrollment period is up, so it's important to update your status rather than wait for renewal.
