• Generic Name: factor XIII
• Dosage Forms: injection
• Other Brand Names: Corifact, Tretten

Corifact (factor XIII) is used to prevent bleeding episodes in people with a hereditary bleeding disorder caused by a deficiency of Factor XIII.

Factor XIII (thirteen) is a naturally occurring protein in the blood that helps blood to clot. A lack of clotting factors can cause uncontrolled bleeding, as the blood is unable to clot properly. This medicine works by temporarily raising levels of these factor XIII in the blood to aid in clotting.

Corifact will not treat a bleeding episode that has already begun.

Corifact may also be used for purposes not listed in this medication guide.
