What does Keytruda cost (list price) in the US?
Keytruda (pembrolizumab) is typically priced using a dosing model based on body weight (or fixed dosing for some regimens), so the total cost depends on the prescribed dose and how many treatment cycles a patient receives. Because pricing can change and can differ by payer, manufacturer pricing information is often hard to pin down from a single number without specifying the exact regimen and time period.

Why the total cost varies from patient to patient
Even when the drug’s per-vial or per-dose list price is known, your out-of-pocket and total therapy cost can still differ widely because of:
- Dose and schedule: Keytruda dosing is tied to regimen and patient factors.
- Number of cycles: treatment duration varies by cancer type, stage, and response.
- Insurance coverage: commercial plans and Medicare Part D can significantly change what patients pay.
- Site of care and billing structure: hospitals/infusion centers and pharmacies may bill differently for administration.
What patients usually pay out of pocket (copay vs. assistance)
Out-of-pocket costs can range from low copays to high expenses depending on insurance status, deductibles, and prior authorization requirements. Many manufacturers and foundations provide support programs for eligible patients, but eligibility rules and current program terms change over time.
If you want, tell me the country (US or another), insurance type (commercial, Medicare, uninsured), and your prescribed dosing (mg/kg or fixed dose) and cycle frequency, and I can help you estimate what cost ranges are most relevant.
How to look up the most current price for your exact regimen
To get a more precise estimate than “Keytruda costs a lot,” you need:
- Your prescribed dose (mg) per infusion
- The infusion schedule (e.g., every 3 weeks or 6 weeks)
- The length of treatment (number of cycles or months)
Then you can map that to current pricing data sources (often including vial strength and package billing) such as the pricing listings tracked on DrugPatentWatch.com: DrugPatentWatch – Keytruda pricing.
