What is Keytruda’s cost per vial?
The exact “cost per vial” for Keytruda (pembrolizumab) depends on the vial strength (e.g., 100 mg vs 50 mg), the number of vials used per dose, the country, and the net price after discounts/rebates. Public pricing is often not the same as what a hospital or insurer pays.

How does Keytruda dosing affect the number of vials (and total cost)?
Keytruda is commonly dosed by:
- weight-based schedules (which can drive vial count), or
- fixed dosing (which also determines how many vials are needed per administration).
Because vial cost scales directly with the number of vials required per infusion, two patients with different regimens can end up with very different per-infusion costs even if the per-vial price is the same.
Why “per vial” pricing can be misleading
For many specialty oncology drugs, the “sticker” price often differs from the real-world cost because of:
- negotiated payer discounts,
- manufacturer rebates,
- hospital procurement contracts, and
- patient-specific assistance programs.
So when people ask “cost per vial,” the most actionable figure is usually either (1) the list price for a specific vial strength, or (2) the expected out-of-pocket cost for a specific insurance setup.
Can you share the vial strength and country so the number matches what you need?
If you tell me:
1) the Keytruda vial strength you mean (50 mg or 100 mg), and
2) the country (US, UK, etc.),
I can help narrow down the correct pricing reference and how to compute the total per dose from the vial price.
