What is Kcentra (4-factor PCC) used for?
Kcentra is a four-factor prothrombin complex concentrate (PCC) used to reverse the effects of warfarin in people who have serious bleeding or need urgent surgery or an invasive procedure. [1]
How does Kcentra work?
Kcentra provides clotting factors II, VII, IX, and X (as well as proteins C and S). These factors help restore coagulation when warfarin has reduced the body’s ability to make vitamin K–dependent clotting factors. [1]
Who is Kcentra for, and what conditions does it address?
Kcentra is indicated for patients on warfarin (or those with warfarin effect) who have:
- Serious bleeding, or
- Need urgent surgery or an invasive procedure
Kcentra is specifically tied to warfarin reversal rather than general treatment of all bleeding types. [1]
What are common safety concerns people ask about?
As with other PCC products, major risks include thromboembolic events (for example, blood clots) and other complications related to restoring clotting activity. Patients and clinicians typically weigh these risks against the urgency of stopping bleeding or preparing for surgery. [1]
