Searching "Sanofi Patient Assistance" usually means one of two things: you need help affording insulin like Lantus or Admelog, or you were prescribed a Sanofi specialty drug — Dupixent, Sarclisa, or a rare-disease treatment — and got handed a program name you'd never heard of.
Here's the part that trips people up: Sanofi doesn't run one assistance program. It runs several, split by therapeutic area, each with its own phone number, income rules, and application. Applying to the wrong one wastes weeks.
This guide sorts out which program covers your medication, what the 2026 income and insurance rules actually are, and exactly how to get an application moving — plus what to do while you wait and what to do if you're turned down.
What Is Sanofi Patient Connection
Sanofi Patient Connection is the core assistance program, delivered through Sanofi Cares North America. It has three components that work together:
- Patient Assistance Connection: provides eligible Sanofi medications at no cost to qualifying patients.
- Coverage Connection: helps determine your insurance coverage and whether prior authorization is needed before or during the application process.
- Resource Connection: researches other local or national resources if you don't qualify for free medication.

The Four Sanofi Assistance Programs at a Glance
Sanofi's largest consumer medications are split across four separate support structures. Confirming which one applies to your prescription before you apply saves real time.
| Program | Typical Medications | Phone |
|---|---|---|
| Sanofi Patient Assistance Connection | Lantus, Admelog, Apidra, Soliqua, Lovenox, Mozobil, Multaq, select vaccines | 1-888-847-4877 |
| CareASSIST | Sarclisa and other oncology products | 1-833-930-2273 |
| CareConnect | Rare-disease specialty drugs (Sanofi Genzyme portfolio, e.g., Cerezyme, Fabrazyme, Myozyme/Lumizyme, Nexviazyme) | 1-800-745-4447 |
| DUPIXENT MyWay | Dupixent (jointly run with Regeneron) | 1-844-387-4936, option 1 |
Applying to the wrong program is the single biggest reason people think they've been "ignored." A Lantus application won't be reviewed by the CareASSIST team, and a Dupixent question won't be answered by Patient Connection.
Eligibility for Sanofi Patient Assistance Connection
Broadly, you're a strong candidate for Patient Assistance Connection if:
- You're a U.S. resident (including DC, Puerto Rico, and other U.S. territories) under the care of a licensed prescriber.
- You have no prescription drug coverage, or you have Medicare without adequate coverage for the specific medication.
- Your household income is at or below 400% of the federal poverty level.
- Your medication appears on the current Patient Assistance Connection medication list.
You're less likely to qualify if:
- You have commercial (private/employer) insurance — a copay card is usually the better fit.
- Your income is above the 400% FPL threshold.
- You may be eligible for Medicaid but haven't yet documented a denial.
- Your prescribed medication isn't Sanofi-manufactured or isn't on the covered list.
Income Limits for 2026
Patient Assistance Connection ties its cutoff to 400% of the federal poverty level, updated annually by HHS. DUPIXENT MyWay uses a separate, flat income limit instead of a percentage.
| Household Size | Patient Assistance Connection (400% FPL) | DUPIXENT MyWay PAP |
|---|---|---|
| 1 Person | ~$62,600 | $100,000 flat (individual) |
| 2 People | ~$84,600 | Evaluated case-by-case |
| 3 People | ~$106,600 | Evaluated case-by-case |
| 4 People | ~$128,600 | Evaluated case-by-case |
Note: DUPIXENT MyWay's Patient Assistance Program reviews eligibility case-by-case beyond its stated income guideline, and separately supports Medicare Part D patients experiencing a coverage gap. It's a materially different structure from the standard Patient Connection formula, so don't assume the FPL table applies if you're asking about Dupixent specifically.
Medications Covered by Sanofi Patient Connection
Not every Sanofi product is on the Patient Assistance Connection list. Here's how the major categories break down.
| Category | Examples | Program |
|---|---|---|
| Insulin / diabetes | Lantus, Admelog, Apidra, Soliqua 100/33 | Patient Assistance Connection |
| Anticoagulant | Lovenox | Patient Assistance Connection |
| Cardiac arrhythmia | Multaq | Patient Assistance Connection |
| Stem-cell mobilization | Mozobil | Patient Assistance Connection |
| Vaccines | Select Sanofi vaccines (age 19+ required, except Imovax Rabies) | Patient Assistance Connection |
| Oncology | Sarclisa | CareASSIST |
| Rare disease / Sanofi Genzyme | Cerezyme, Fabrazyme, Myozyme/Lumizyme, Nexviazyme | CareConnect |
| Dermatology / immunology | Dupixent | DUPIXENT MyWay |
Thyrogen applicants must be at least 18. If your specific medication isn't listed here, call Sanofi Customer Relations at 1-800-633-1610 to confirm which program, if any, applies. Related programs from other manufacturers — like the Novo Nordisk Patient Assistance Program — follow a similar structure if you're comparing options across insulin brands.
Patient Assistance vs. Sanofi Copay Cards
These solve different problems and are frequently confused.
| Feature | Patient Assistance Connection | Sanofi Copay Card |
|---|---|---|
| Best for | Uninsured patients; Medicare patients without drug coverage | Commercially insured patients |
| Cost | $0 | Reduced copay (varies by product and plan) |
| Income limit | 400% FPL | None |
| Medicare/Medicaid eligible? | Medicare: yes, if uncovered; Medicaid: usually no | No — federal law prohibits use with government insurance |
| Who submits it | Prescriber's office | Patient (self-enrollment, online or in-pharmacy) |
Insurance Status Requirements
| Insurance Situation | Typically Eligible for Patient Assistance Connection? |
|---|---|
| No health insurance at all | Usually Yes |
| Medicare without coverage for the specific drug | Usually Yes |
| Potentially Medicaid-eligible but not yet enrolled | Must document Medicaid denial first |
| Commercial/private insurance | Usually No — use a copay card instead |
If you're navigating Medicare specifically, our Medicare Part D guide and Extra Help (LIS) explainer cover how those programs interact with manufacturer assistance.
Required Documents
| Document | Purpose |
|---|---|
| Completed two-page Sanofi Patient Connection application | Patient and prescriber sections, both required |
| Proof of income | Confirms household income against the 400% FPL threshold |
| Proof of insurance status | Confirms no coverage, or Medicare without coverage for this drug |
| Medicaid denial letter | Required only if you may be Medicaid-eligible but aren't enrolled |
| Valid prescription | Confirms the specific product and dose requested |
How to Apply, Step by Step
Confirm which program applies to your medication
Check the medications table above, or call Sanofi Customer Relations at 1-800-633-1610 if you're unsure which program covers your prescription.
Download the application with your prescriber
The Sanofi Patient Connection application is completed jointly by you and your licensed healthcare provider — it can't be submitted by the patient alone.
Attach income and insurance documentation
Include proof of income and documentation of your insurance status. If you may qualify for Medicaid, attach your denial letter as well.
Submit by fax or mail
Fax the completed application to 1-888-847-1797, or mail it to Sanofi Patient Connection, PO Box 222138, Charlotte, NC 28222–2138.
Ask about a bridge supply if you need medication immediately
After submitting, call 1-888-847-4877 and ask about the Temporary Access Program for a 30-day supply while your full application processes.
Wait for a decision
A complete, signed application is typically processed in 5–7 business days. Incomplete applications take longer while Sanofi follows up with your provider's office.
Ready to apply?
Call Sanofi Patient Connection at 1-888-847-4877 (Monday–Friday, 9am–8pm ET), or download the application to complete with your prescriber.
Go to Sanofi Patient Connection → See Required DocumentsThe Temporary Access Program (Bridge Supply)
If you can't wait 5–7 business days, the Temporary Access Program can bridge the gap. After your full application is submitted, call Sanofi Patient Connection and tell the representative you're interested in temporary access. You'll answer a few eligibility questions, and if approved, you'll receive a voucher ID and pharmacy numbers to redeem at your pharmacy for an immediate 30-day supply alongside a valid prescription.
The voucher only works after your full application is submitted — it's a bridge, not a substitute for completing the standard application.
Decision Tree: Which Sanofi Program Do You Need?
Step 1: What is your medication?
Insulin/Lovenox/Mozobil/Multaq/vaccine → Patient Assistance Connection. Sarclisa or another oncology drug → CareASSIST. A rare-disease Sanofi Genzyme product → CareConnect. Dupixent → DUPIXENT MyWay.
Step 2: Do you have commercial insurance that covers this drug at a manageable cost?
✔ Yes → Use a copay card instead of patient assistance.
✖ No → Continue to Step 3.
Step 3: Is your household income within the relevant program's limit?
✔ Yes → You're a strong candidate — start the application with your prescriber.
✖ No → Ask about Resource Connection or a state pharmaceutical assistance program instead.
Approval Timelines
| Situation | Typical Timeframe |
|---|---|
| Complete, signed application | 5–7 business days |
| Missing information | Delayed until Sanofi follows up with your provider |
| Temporary Access Program voucher | Same-day, after full application is submitted |
| CareASSIST copay reimbursement | Can apply retroactively for treatments up to 180 days before enrollment |
How Medication Is Delivered
Approved Patient Assistance Connection medication ships to your prescriber's office, not your home — a meaningful difference from programs that mail directly to patients. You'll need to coordinate pickup with your provider's office once shipment arrives. DUPIXENT MyWay, by contrast, ships approved medication directly to the patient's home address.
Renewing Your Enrollment
Patient Assistance Connection enrollment isn't indefinite. Plan ahead for renewal:
- Submit updated income and insurance documentation before your current approval period ends.
- Confirm your prescriber's office is ready to resubmit the prescriber section, since renewal requires a new signature.
- For DUPIXENT MyWay specifically, Medicare Part D patients must reapply each calendar year, or by December 31 to be considered for the following year.
- Report any change in insurance status right away, since gaining adequate coverage can end eligibility mid-cycle.
Pros and Cons
Pros
- Medication cost drops to $0 for approved patients
- Temporary Access Program bridges the wait for urgent needs
- Coverage Connection helps sort out insurance confusion for free
- Fast 5–7 business day turnaround for complete applications
- Multiple specialized programs match the complexity of Sanofi's product line
Cons
- Four separate programs make it easy to apply to the wrong one
- Patients can't self-submit — a prescriber must complete their section
- Medication ships to the provider's office, not home, for most Patient Connection drugs
- Commercially insured patients are excluded from free-medication assistance
- Renewal documentation requirements repeat annually
Common Mistakes That Delay Applications
- Applying to Patient Assistance Connection for a Dupixent, Sarclisa, or rare-disease prescription instead of the correct dedicated program
- Submitting the application without the prescriber section completed
- Applying while commercially insured instead of using a copay card
- Skipping the Medicaid denial letter when it's required
- Assuming medication ships home when it actually ships to the provider's office
- Waiting until medication runs out before starting the renewal paperwork
What to Do If You're Denied
| Reason for Denial | Next Step |
|---|---|
| Income above 400% FPL | Ask Resource Connection about foundation grants or state pharmaceutical assistance |
| Missing documentation | Resubmit with all required attachments |
| Commercial insurance already in place | Use a Sanofi copay card instead |
| Wrong program applied to | Resubmit through the correct program (CareASSIST, CareConnect, or DUPIXENT MyWay) |

Real Patient Scenarios
Scenario: Uninsured, newly diagnosed with Type 1 diabetes
A single applicant with no insurance and income under $62,600 is prescribed Lantus and Apidra. Both are on the Patient Assistance Connection list, so a single application covering both medications, completed with their endocrinologist, is the right move.
Scenario: Commercially insured, prescribed Dupixent for eczema
A patient with employer insurance is prescribed Dupixent but faces a high copay. Because they have commercial coverage, the DUPIXENT MyWay Copay Card — not the patient assistance program — is the faster, more appropriate option, potentially reducing their copay to $0 up to the annual maximum.
Scenario: Medicare patient prescribed a rare-disease enzyme therapy
A Medicare Part D patient prescribed a Sanofi Genzyme rare-disease therapy finds their plan's cost-sharing unaffordable. Because this falls under the CareConnect program rather than Patient Assistance Connection, they call 1-800-745-4447 to start the correct application with their case manager.
