Who Qualifies for the Sanofi Patient Connection?
If you need Lantus (insulin glargine) but cannot afford it, you may be able to get it for free through the Sanofi Patient Connection program. This program is designed for people who are uninsured or whose insurance does not cover Lantus. To qualify as a single-person household, your annual income must be at or below $60,240. Income limits increase with household size, so larger families may still qualify even with higher earnings. Both uninsured patients and some insured patients — including certain Medicare Part D enrollees — may be eligible. If you meet the income and insurance requirements, Sanofi will ship your Lantus directly to your home at no charge.

About Lantus (insulin glargine)
Lantus is a long-acting insulin analog made by Sanofi. It is FDA-approved to help manage blood sugar levels in adults and children with Type 1 diabetes, and in adults with Type 2 diabetes. Lantus is typically taken once daily and works over a 24-hour period to provide steady insulin activity. Without insurance or financial assistance, Lantus can cost several hundred dollars per month, placing it out of reach for many patients. The Sanofi Patient Connection program exists specifically to help people who face this cost barrier access the medication their doctor has prescribed.

Income Eligibility: Full Breakdown
Sanofi uses income thresholds based on 400% of the 2025 Federal Poverty Level (FPL) to determine eligibility. The table below shows the maximum annual income allowed by household size:
| Household Size | Max Annual Income |
|---|---|
| 1 person | $60,240 |
| 2 persons | $81,760 |
| 3 persons | $103,280 |
| 4 persons | $124,800 |
To verify your income, you will typically need to provide your most recent federal tax return (Form 1040), a W-2, or three months of recent pay stubs. If your income slightly exceeds these limits, do not assume you are automatically disqualified. Sanofi notes that limits may be adjusted based on cost of living in certain geographic areas or specific patient circumstances. It is worth applying or calling the program to ask, even if your income is close to the cutoff. If your household size is not listed above — for example, five or more members — contact Sanofi directly at (888) 847-4877 to get the applicable limit for your situation.

Once Sanofi receives your fully completed application, the review process takes approximately two business days. Approval notification is typically sent to you or your healthcare provider's office. If approved, your Lantus will be shipped directly to your home address — you do not need to pick it up at a pharmacy. No payment is required at delivery.
