What is tranexamic acid? What is tranexamic acid used for?

  • Tranexamic acid promotes the clotting of blood and thereby reduces bleeding due to tooth extractions in people with hemophilia. People with hemophilia bleed easily because they lack a specific blood protein necessary for forming blood clots.
  • Tranexamic acid is a man-made amino acid derivative that increases blood clotting by preventing the breakdown of fibrin. Fibrin is a protein and an important component of blood clots. It is broken down by another protein called plasmin. Tranexamic acid blocks the action of plasmin on fibrin and thereby prevents the breakdown of fibrin. This leads to stabilization and preservation of fibrin in blood clots. This helps reduce bleeding after a tooth extraction.
  • The FDA approved tranexamic acid injection in December, 1986.
