US Brand Names
Protein C is a protein produced naturally in the body. It is used in patients with severe congenital protein C deficiency to prevent and treat venous thrombosis (harmful blood clots form in the blood vessels) and purpura fulminans (harmful blood clots form in the skin) .
Protein C is made from donated human blood. Some human blood products have transmitted certain viruses to people who have received them. The risk of getting a virus from medicines made from human blood has been greatly reduced in recent years. This is the result of required testing of human donors for certain viruses, and testing during the making of these medicines. Although the risk is low, talk with your doctor if you have concerns .
