Lilly Cares Foundation Patient Guide: How to Get Humulin N at Low or No Cost
Humulin N (insulin human (NPH) isophane suspension) is an intermediate-acting insulin used to help control blood sugar levels in people with diabetes. The Lilly Cares Foundation program, run by Eli Lilly and Company, provides this medication at no cost to eligible patients who meet income, residency, and insurance criteria.[1][2]
About Humulin N
Humulin N is a man-made insulin that starts working in 1 to 2 hours, peaks in 4 to 12 hours, and lasts up to 24 hours. It's commonly prescribed for type 1 and type 2 diabetes to maintain steady blood glucose control, often used alongside short-acting insulins or oral medications. Always follow your doctor's instructions for dosing, storage (refrigerate unopened vials), and injection technique to avoid lows or highs in blood sugar.[2][3]
This guide explains how to qualify for free Humulin N through Lilly Cares, a program designed for uninsured, underinsured, or low-income U.S. residents. Medications like Humulin N fall under Group 2, allowing eligibility for those with no insurance or Medicare Part D and household income at or below 400% of the Federal Poverty Level (FPL).[1][2]
Who Qualifies?
To join Lilly Cares, you must:
- Be a legal U.S. resident (including Puerto Rico and U.S. Virgin Islands).[2][3]
- Have a prescription for a qualifying Lilly medication like Humulin N from your healthcare provider.[1][2]
- Meet household income guidelines (detailed below).[2]
- Have acceptable insurance status (see section below): no Medicaid, full Low-Income Subsidy (LIS/Extra Help), or VA Benefits.[2][3]
Income Eligibility Breakdown
Lilly Cares uses household adjusted gross income compared to the Federal Poverty Level (FPL). For Humulin N (Group 2 medications), eligibility is for households at or below 400% FPL if you have no insurance or Medicare Part D.[1][2]
Here's a table with 2026 FPL estimates (actual amounts update yearly; check www.lillycares.com or call 1-800-545-6962 for current figures):
| Household Size | 100% FPL | 400% FPL (Group 2 Max for Humulin N) |
|---|---|---|
| 1 | $15,060 | $60,240 |
| 2 | $20,440 | $81,760 |
| 3 | $25,820 | $103,280 |
| 4 | $31,200 | $124,800 |
Notes: Add ~$5,760 per additional person for 100% FPL (multiply by 4 for 400%). Enter 0 if no income. Program may request proof like tax returns or pay stubs.[1][2][3]
Insurance Requirements
You must have no insurance or Medicare Part D. Some Medicare Part D patients qualify for Group 2 drugs like Humulin N if income ≤400% FPL.[1][2] You cannot be on:
- Medicaid
- Full LIS/Extra Help
- VA Benefits
If your plan requires PAP enrollment as a condition for coverage, you don't qualify. For Group 4 meds (not Humulin N), additional rules apply, but check Lilly Cares' insurance verification page if needed. Provide insurance docs if applying for certain groups.[2][3]
