Not sure which kind of help you qualify for?

Keytruda offers more than one kind of program, and they have opposite rules:

  • Have private insurance? The copay card can cut your monthly cost - but it can’t be used with Medicare, Medicaid, the VA, or Tricare.
  • Uninsured or low-income? The patient assistance program may give you Keytruda free or nearly free, if your income is under its limit.

We show both programs, and the real income limits, below. Or read the full copay card vs patient assistance guide
