Dupixent (dupilumab) – How Much It Typically Costs in the United States
| Item |
Typical Cost (US) |
| List price per vial (200 mg) |
~$1,700–$1,900 |
| Monthly treatment (two 200 mg vials) |
~$3,400–$3,800 |
| Annual cost (12 months) |
~$41,000–$45,600 |
| Typical out‑of‑pocket (average) |

Note: These figures are based on the FDA‑approved retail price (the “list price”) and represent the amount a pharmacy would bill an insurer. Actual out‑of‑pocket costs vary widely because of insurance coverage, pharmacy benefit manager (PBM) rebates, and the manufacturer’s discount programs.
1. Where the Numbers Come From
| Source |
How it’s used |
| CMS National Drug Code (NDC) database |
Shows the manufacturer’s listed price per vial. |
| Manufacturer (Sanofi) |
Provides the official retail price and the patient‑assistance program details. |
| Pharmacy Benefit Manager (PBM) reports |
Give an estimate of the average net price after rebates. |
| Insurance claims data |
Illustrate the typical out‑of‑pocket amounts for commercial and Medicare plans. |
The list price is not the price that insurers or patients actually pay. Rebate programs negotiated between PBMs and Sanofi can lower the net cost to insurers by 20‑30 %, and many patients receive discounts through the PAP.
2. Typical Insurance Coverage Scenarios
| Insurance Type |
Copay / Coinsurance |
Typical Out‑of‑Pocket |
| Commercial PPO |
20‑30 % of the net price after PBM rebate |
$70–$200/month |
| Commercial HMO |
Fixed co‑pay ($40–$80/month) |
$40–$80/month |
| Medicare Part D |
20 % of net price (after rebate) |
$70–$150/month |
| Medicaid |
Variable; many states cover 100 % |
$0–$30/month (often $0 after 12 months) |
- Prior authorization is usually required, and the pharmacy may need to provide medical documentation of a severe atopic dermatitis, asthma, or chronic rhinosinusitis with nasal polyps diagnosis.
- Step‑down therapies (e.g., topical steroids) are often required before approval.
3. Patient‑Assistance Program (PAP)
Sanofi’s Dupixent PAP is designed to reduce copays for patients who:
- Have a qualifying prescription (Dupixent).
- Have no other drug coverage that can pay for Dupixent (i.e., out‑of‑pocket or out‑of‑network).
- Meet the income eligibility criteria (varies by state; typically > 125 % of federal poverty level).
Benefits:
| Phase |
Copay |
| Months 1–3 |
$0 |
| Months 4–12 |
$0–$50/month (most patients pay $0) |
| Beyond 12 months |
$0 (if continued eligibility) |
The PAP does not cover pharmacy fees, infusion costs, or medical monitoring; those remain with the insurer.
4. How to Get the Best Price
- Ask Your Provider About the PAP – They can help you apply if you’re eligible.
- Check Your Insurance Formulary – Some plans list Dupixent as a preferred biologic; others may require prior authorization.
- Compare Pharmacy Options – Some specialty pharmacies negotiate lower patient cost sharing; they may also provide free medication samples for the first injection.
- Use a Prescription Discount Card – These are free, but only work on the retail price (not the net price paid by insurers).
- Explore State Assistance Programs – Some states have additional rebates for biologic treatments.
