About bleeding disorders with inhibitors

Dive into the details of bleeding disorders with inhibitors—what they are, whom they affect, when they can occur, and more.

What are inhibitors?

When our immune system identifies a foreign substance, it makes antibodies that will specifically recognize that substance and destroy it to defend us from harmful diseases and/or illnesses.

Inhibitors are antibodies that are made by our immune system.1,2

Having inhibitors does not lead to more frequent bleeding episodes than those with bleeding disorders who do not have inhibitors, but inhibitors make it more difficult to stop a bleeding episode, because they prevent the treatment from working.2

Luckily, there are other treatment options available.
