How Much Is Vyvgart Without Insurance? | Real-World Costs

Sticker prices for efgartigimod treatments can be confusing, since there are two ways to receive it: an intravenous infusion at 10 mg/kg once a week for 4 weeks, or a fixed subcutaneous version given once a week for 4 weeks. Clinics bill drug, supplies, and staff time separately. Below is a clear snapshot of typical product-only pricing based on recent manufacturer list prices and dosing.

Cash Price Snapshot By Form

Form	List Price Per Dose*	Estimated 4-Dose Cycle*
IV efgartigimod (weight-based)	$12,628–$18,943 per infusion	$50,514–$75,770
Hytrulo vial (clinic-administered SC)	$16,088 per injection	$64,354
Hytrulo prefilled syringe (self-injection)	$16,732 per injection	$66,928

*Product list prices (WAC) as of 2024–2025; excludes facility fees, supplies, pharmacy markups, and professional services.

Cost Without Insurance: Vyvgart Price Ranges And Context

Two factors set the baseline: the drug’s list price and the dosing schedule. For the IV route, dose is tied to body weight, so some people need two vials each week and others need three. The subcutaneous versions use a fixed weekly amount, so the drug quantity stays the same each dose.

Next, the place of care adds charges. Infusion centers and hospitals add overhead. Home infusion and self-injection can trim facility fees, though a home nurse visit may carry a charge. Pharmacies and clinics may also apply a buy-and-bill margin on top of list price. Finally, the number of cycles per year varies by response; some people space cycles farther apart, while others return sooner under a prescriber’s guidance.

Dose And List Price Details (With Sources)

Intravenous Route

The IV version uses 10 mg/kg once weekly for 4 weeks; those at or above 120 kg receive 1,200 mg weekly, which equals three vials per infusion. Recent disclosures list each 400 mg vial at $6,314.19. That yields two-vial doses near $12,628 and three-vial doses near $18,943, before any service fees. For full dosing language, see the FDA Prescribing Information. For the current catalog price by vial, see the manufacturer’s WAC disclosure.

Subcutaneous Route

The Hytrulo vial contains 1,008 mg efgartigimod with hyaluronidase and is taken once weekly for 4 weeks in a clinic. The WAC lists that vial around $16,088 per dose. The prefilled syringe delivers 1,000 mg once weekly for 4 weeks and carries a WAC of $16,732 per dose. Self-injection can remove facility overhead but does not change the product price. See the Hytrulo WAC disclosure here.

Estimated IV Cost By Body Weight

Use this table to gauge the product portion of an IV cycle. It shows common weight bands, the number of vials needed each week, and the approximate product cost across the 4-dose starter cycle.

Body Weight	Vials Per Weekly Dose	Approx. Product Cost (4 Doses)
50–79 kg	2 vials	$50,514
80–119 kg	3 vials for some weeks*	$63,142–$75,770
≥120 kg	3 vials	$75,770

*Dose is 10 mg/kg; those near 120 kg may land at 2 or 3 vials per week depending on exact weight.

Realistic All-In Totals By Setting

Drug cost sets the floor. The site of care and service pattern set the ceiling. At a hospital outpatient department, bills often include higher facility rates, pharmacy handling, IV chair time, and supplies. An independent infusion center may bill lower facility charges. Home infusion bundles a nurse visit, pharmacy services, and delivery. Subcutaneous self-injection with the prefilled syringe removes repeated visit fees in many cases, though the first dose may be taught in clinic.

Because each market negotiates rates, there is no single surcharge to apply. A practical planning range is to add 10%–30% on top of product list price when estimating IV center totals, and 0%–15% for clinic-based subcutaneous visits. Home infusion sits in between. Ask the actual site for a written estimate that separates drug from services.

How Often Are Cycles Repeated?

Efgartigimod is given in cycles. After the first 4 doses, the prescriber reassesses. If symptoms remain controlled, the next cycle can be deferred. If symptoms return, the next cycle may start sooner. The label leaves timing to clinical judgment. In practice, some patients repeat every few months; others need fewer rounds. This variation is one reason yearly totals vary so widely.

Yearly Budgeting Scenarios

Here are simple scenarios that show how totals can scale:

Light Use

One 4-dose cycle of Hytrulo self-injection in a year: product total near $66,928, plus one or two training visits. If treatment holds symptoms for many months, this can be the whole year’s spend.

Moderate Use

Two cycles of IV therapy at two vials per week: product total near $101,028, plus infusion services. Add facility charges and pharmacy handling as quoted by the site.

High Use

Three cycles at three vials per week: product spend near $227,310, not counting services. This level reflects heavier need and should be planned with written quotes and a payment plan.

Common Billing Questions, Simplified

Which Codes Identify The Drug?

Medical claims use HCPCS J-codes tied to the product. The IV version uses J9332 (billed by 2 mg units). The Hytrulo products use J9334 (also billed by 2 mg units). Quotes that show those codes help you match the drug lines to the dose you expect.

Why Do I See So Many Line Items?

Expect separate lines for drug units, pharmacy services, IV administration time, nursing, and supplies. Those services are standard in infusion care. For subcutaneous self-injection, the ongoing lines shrink because no chair time is needed after training.

Can A Specialty Pharmacy Ship The Drug?

Yes. Some prescribers prefer a specialty pharmacy to dispense the product and ship it to the site or to you for home use. Others keep buy-and-bill. Ask for both quotes; the acquisition channel can change the price the clinic presents to you.

What To Ask Your Clinic

• Which route fits my case, and how many milligrams per dose?
• How many vials or syringes per week will that take?
• How many cycles do you expect this year if I respond as planned?
• Can I use the prefilled syringe at home after training?
• Will you bill through a specialty pharmacy or buy-and-bill? Please quote both.
• What are your facility, pharmacy, and nursing fees for each visit?
• Do you offer prompt-pay adjustments or interest-free plans?

Ways To Lower What You Pay

Manufacturer Programs

Argenx runs patient services for gMG and CIDP, including benefits checks and copay aid for those who qualify. Uninsured or underinsured patients may be directed to foundation grants when available. Start with the product site and ask for a benefits review.

Site Of Care Choices

Ask whether a non-hospital infusion center or home care is possible for you. Site of care can reshape the final bill, since drug cost is the same but facility charges change. If you can use the prefilled syringe, your prescriber can teach you to self-inject, which may remove visit fees.

Buy-And-Bill Vs. Specialty Pharmacy

Some clinics order the drug and bill you (buy-and-bill). Others send a prescription to a specialty pharmacy that ships the product to the clinic or to you for home use. In some markets, the specialty pharmacy route yields a lower acquisition price than a clinic’s markup. Ask your team to compare both pathways.

Appeals And Payment Plans

Even without coverage, clinics may offer prompt-pay adjustments or extended plans. If you later gain coverage, keep records; you may be able to appeal prior denials with proof of need and response.

Where These Numbers Come From

Two public sources anchor the math. First, the FDA label spells out dosing for the IV route, including the 10 mg/kg schedule and the three-vial dose for people at or above 120 kg. Second, state-mandated WAC disclosures list current catalog prices for both the IV vial and the Hytrulo products. Those publications do not include discounts, but they set a stable yardstick you can use for planning.

To see the raw documents, check the FDA label for the IV product, the WAC disclosure for the IV vial, and the WAC disclosure for Hytrulo. For a plain-English overview of both routes, see the company’s dosing overview.

Insurance Notes For Reference

When people do have coverage, the billing route can flip out-of-pocket math. IV therapy often bills under medical benefits, which use deductibles and coinsurance tied to the site. The prefilled syringe can bill under pharmacy benefits, which allows retail copay cards in many plans. Those distinctions explain why some clinics steer people to one route over another, even when drug effect is the same. For cash payers, the lesson is simple: ask for the lowest acquisition price available to the site and request the estimate in writing.

Many clinics can also run a benefits check and provide a good-faith estimate. Even if you intend to pay cash, that process can reveal negotiated rates that lower your bill.

Method Notes

All figures above refer to product list prices in the United States. Real bills vary. Your prescriber decides the route and timing. Quotes from your infusion center or pharmacy provide the only precise totals for your situation.

Numbers here are rounded to the nearest dollar for clarity, using list prices disclosed in 2024–2025. Service fees change by region, contract, and site. Always request written quotes tied to J-codes, dose, and cycle length so estimates match your plan and timing.
