How much did Keytruda cost per month in 2014?
Public pricing for Keytruda (pembrolizumab) in 2014 isn’t a single fixed “per-month” number because the drug was approved in 2014 and then billed around an on-label dosing schedule. In the U.S., Keytruda was commonly dosed at 2 mg/kg every 3 weeks (or, later in other regimens, 10 mg/kg every 2 or 3 weeks), so a “per month” cost depends on the patient’s weight and the specific dose frequency used.

Why “per month” varies: dose schedule and patient weight
Even if you know the per-vial or per-milligram list price, monthly cost changes with:
- Dose used (mg/kg strength and whether it’s given every 2 or 3 weeks).
- Patient weight (mg/kg dosing scales to body size).
- Whether billing is based on the number of vials used for a given dose.
That makes a simple “$X/month” number for 2014 misleading unless it states assumptions (e.g., a specific weight and dosing interval).
Where to find a month-based estimate that matches 2014 dosing
If you’re trying to estimate Keytruda’s 2014 monthly price for a typical patient, you need both:
1) The drug’s early U.S. list price assumptions for that period, and
2) The dosing pattern used in the estimate (often 2 mg/kg every 3 weeks for early regimens).

If you tell me the weight and dosing interval, I can convert it to a monthly figure
If you share the assumptions you want (for example, “2 mg/kg every 3 weeks” and “70 kg”), I can translate the underlying per-dose pricing into an approximate “per month in 2014” cost using those parameters.
