Defibrotide Injection


Defibrotide injection is used to treat adults and children with hepatic veno-occlusive disease (VOD; blocked blood vessels inside the liver, also known as sinusoidal obstruction syndrome), who have kidney or lung problems after receiving a hematopoietic stem-cell transplant (HSCT; procedure in which certain blood cells are removed from the body and then returned to the body). Defibrotide injection is in a class of medications called antithrombotic agents. It works by preventing the formation of blood clots.
