What does Darzalex (daratumumab) cost in the US?
Exact “the price” of Darzalex in the US depends on the dose, dosing schedule, treatment setting, and the payer (commercial insurance, Medicare/Medicaid, or patient assistance). Darzalex is a high-cost biologic, and list price often differs a lot from what patients actually pay after insurance and rebates.

Why can Darzalex price vary so much from patient to patient?
Even for the same drug, the total cost can change because:
- Dosing is weight-based and may require different vial amounts per infusion.
- Treatment duration varies by line of therapy and regimen.
- Hospitals/infusion centers and pharmacies may bill differently depending on the site of care.
- Insurance contracts and negotiated rates can drive the actual billed/paid amount far below list price.
Is there more than one Darzalex product—and can that affect price?
Yes. Darzalex is marketed in different formulations (notably intravenous Darzalex and subcutaneous Darzalex Faspro), and those can have different pricing and billing codes in the US. If you’re comparing “Darzalex price,” it helps to specify whether you mean IV Darzalex or Darzalex Faspro.
How can patients estimate what they’ll pay in the US?
Patients typically have the lowest out-of-pocket costs when they:
- Use their insurance benefit for the infusion/administration setting (medical benefit vs pharmacy benefit can change cost-sharing).
- Ask the provider for an estimate using the patient’s specific plan and expected dosing.
- Check for manufacturer or copay support programs (where eligible), especially if coverage is commercial.
