While using Kcentra, tell your caregivers right away if you have signs of a blood clot: sudden numbness or weakness, problems with vision or speech, chest pain, cough, wheezing, rapid breathing, swelling or pain in your arms, legs, or stomach.
Tell your doctor if you have ever had a heart attack, stroke, TIA or "mini-stroke", chest pain, severe circulation problems, or a blood clot (especially within the past 3 months).
Kcentra is for use in people who use blood thinners such as warfarin. After you are treated with this medicine, do not start using your blood thinner again until your doctor tells you to.

Kcentra is made from donated human plasma and may contain viruses or other infectious agents. Donated plasma is tested and treated to reduce the risk of contamination, but there is still a small possibility it could transmit disease. Ask your doctor about any possible risk.
How is Kcentra given?
Kcentra is given as an infusion into a vein. A healthcare provider will give you this injection.
After you are treated with Kcentra, do not start using your blood thinner again until your doctor tells you to.
