How Much Is Regeneron Per Dose? | Real-World Prices

People ask about a single price for “Regeneron,” but the number changes by product. The company makes eye injections such as aflibercept, an asthma and eczema biologic co-marketed with Sanofi, and a past COVID-19 antibody. Each product has its own label, strength, and billing rules. This guide lays out current list prices, the add-on fees that appear on bills, and what patients tend to pay with different coverage.

Price By Regeneron Medicine (Quick Guide)

The table below shows headline prices that companies publish or governments agreed to pay. These are list figures. Plans and hospitals often pay less after rebates and contracts, and patients rarely face the sticker price at the counter.

Medicine	Per-Dose List Price*	Notes
Eylea 2 mg (aflibercept)	$1,942.33 (WAC)	Single-dose vial or prefilled syringe; retina use.
Eylea HD 8 mg	$2,625.00 (WAC)	Higher-strength vial; fewer injections for some schedules.
Dupixent (dupilumab)	$3,993.36 per carton	Each carton = 2 injections for the month; list price set by partner site.
REGEN-COV (casirivimab + imdevimab)	$2,100 (U.S. purchase)	Federal price per 1,200 mg dose in 2021 during the public program.

*WAC = wholesale acquisition cost, an undiscounted list price reported to pricing compendia.

Regeneron Dose Pricing—How Much A Single Shot Costs

A “per dose” number can mean different things. For eye injections, the vial itself is the dose, so the list price maps cleanly to the drug line on a bill. For Dupixent, list price appears per carton, and a carton covers two injections in a month. For the COVID-19 antibody, the federal program bought and supplied the drug, so patients often saw $0 for the medicine line while the clinic billed an administration fee.

What Drives The Price Per Dose

Label And Strength

Different strengths can shift the math. The 8 mg version of aflibercept carries a higher price per vial than the 2 mg product, yet it may be used less often during the maintenance phase. Total spend over a year depends on the schedule your retina specialist picks.

Site Of Care

Where you receive the medicine changes the bill. A hospital outpatient department may bill a separate facility fee. A physician office often does not. The drug price can also differ by site due to purchasing contracts.

Insurance Design

Plans set deductibles, coinsurance, and prior authorization rules. On Part B, drugs like aflibercept are usually covered under medical benefits, and coinsurance can be 20% unless a supplemental plan picks it up. On commercial plans, specialty pharmacy delivery and copay cards can lower the out-of-pocket total.

Real Prices For Common Regeneron Products

Aflibercept 2 mg (Ophthalmology)

The current list price per single-dose vial or prefilled syringe is $1,942.33. That is a sticker price before any rebates or discounts. Many patients never see that number due to Part B coverage, copay assistance, or supplemental insurance. Retina offices often “buy and bill,” meaning the clinic purchases the vial and bills your plan after the injection.

Eylea HD 8 mg

The 8 mg vial carries a list price of $2,625. Doctors may choose it for longer intervals between treatments in certain cases. The per-visit drug cost is higher than the 2 mg vial, but total visits across a year can be fewer depending on response.

Dupilumab For Atopic Disease

The list price posted by the product site is $3,993.36 per carton as of January 2025. A carton includes two pens or syringes for the month. Many users pay far less due to coverage rules and copay programs from the manufacturer partner. Prescribers sometimes start with a loading dose, so the first month’s drug spend can be higher than later months.

REGEN-COV During The Federal Program

During 2021, the U.S. government agreed to buy additional lots at $2,100 per 1,200 mg dose and supplied the medicine to sites. Patients generally paid nothing for the drug itself. Clinics billed a separate administration fee set by Medicare and other payers. That program has ended, and care pathways for COVID-19 have changed since then.

Insurance And Out-Of-Pocket Scenarios

Sticker prices tell only part of the story. Below are typical patterns people report at the counter or after a visit. Your bill can differ.

Medicare Part B

Doctor-administered products like aflibercept are usually billed under Part B. Patients often see 20% coinsurance unless a Medigap or retiree plan covers it. If the clinic accepts assignment, the plan pays the Medicare rate, and the office writes off the rest under contract terms.

Commercial Coverage

Employer or individual plans can route drugs in two ways. Buy-and-bill in the office, or ship the medicine through a specialty pharmacy to the clinic for administration. Copay cards from the product’s support program may offset your share if you meet eligibility rules.

Cash Pay

Self-pay transactions are rare for these medicines due to the size of the bill. When they occur, offices may use the list price as a starting point and then apply a discount. Assistance programs can still help some users who meet criteria.

Administration And Facility Fees

Two people can receive the same vial yet pay different totals due to add-on charges. Expect a line for drug administration and, in some locations, a facility fee. For COVID-19 antibodies, Medicare published set payment amounts for the infusion administration. For eye injections, codes and fees differ from site to site, and your explanation of benefits will spell them out.

How To Get A Reliable Estimate

Call The Right Office

Ask your prescribing clinic for a “benefits check.” Staff can run your plan details, check prior authorization steps, and give a ballpark estimate for the drug and the visit. Provide your insurance ID, dosage, and schedule.

Ask About Program Support

Many brand teams sponsor patient support desks that guide people through coverage, copay cards, and pharmacy routing. The help line can explain what “per dose” means for your case and whether you’ll see the drug under the medical or pharmacy benefit.

Confirm The Site Of Care

If your plan sends the medicine through a specialty pharmacy, ask where it will ship and who stores it. If the office buys the vial, confirm that the clinic participates in your network, which affects both drug pricing and facility fees.

Two Linked Sources You Can Trust

For aflibercept, Regeneron posts current wholesale acquisition cost in a public PDF made for prescribers. You can reference that document for the latest per-vial figures. For dupilumab, the branded site lists the current list price per carton and updates the date on the page. Here are those links placed for your convenience:

When A “Per Dose” Number Can Mislead

Loading Doses And Titration

Starting doses can be bigger than maintenance doses. That can double the number of pens or vials in the first visit. Always ask your prescriber which schedule applies to you before you compare prices across brands.

Intervals And Total Visits

A product that costs more per vial can lead to fewer visits over a year. The right comparison is total annual drug spend for your plan and your eye. Retina teams factor that in when they pick a schedule.

Rebates And 340B Purchasing

Hospitals and clinics buy products under complex contracts. A plan may get rebates that lower net price below list. Safety-net sites may buy under 340B rules. Patients rarely see those net numbers on an EOB, so the best path is to focus on your own estimate and benefits.

Examples Of What Patients Pay

These simplified scenarios show how the same drug price can turn into different pocket costs. Numbers are illustrative and not quotes.

Scenario	Typical Patient Share	Why It Looks This Way
Medicare Part B with Medigap	$0	Supplement picks up the 20% coinsurance on buy-and-bill claims.
Commercial Plan, Deductible Met	10%–30% of allowed	Coinsurance applies after deductible; copay card may offset.
Specialty Pharmacy Route	Fixed copay	Plan charges a flat amount per fill; copay program may stack.

Clear Steps To Pin Down Your Price

1. Identify the exact product, strength, and dose you will receive.
2. Ask your clinic for a benefits check and a site-of-care estimate.
3. Request the procedure code for administration and ask whether a facility fee applies.
4. Call the plan’s number on your card and confirm coverage rules for that product.
5. Enroll in the brand’s support program if you qualify.

Plain Takeaways On Regeneron Dose Costs

There isn’t one number that fits every case. Current list prices land near $1,942 per aflibercept 2 mg vial, $2,625 for the 8 mg vial, and $3,993 per month for dupilumab cartons. During the 2021 federal program, the antibody cocktail carried a $2,100 purchase price per dose for the government, and patients often saw $0 for the drug. Your share depends on the plan, site, schedule, and any support you qualify for. A quick call to the clinic and plan can turn a billboard price into your real estimate.
