<qa>  What is an oral antifibrinolytic agent that stabilizes blood clotAn alternative strategy to prevent bleeding and reduce the need for platelet transfusions involves administering Tranexamic Acid, an oral antifibrinolytic agent to stabilize blood clots and reduce bleeding. Tranexamic Acid is safe and effective in many clinical scenarios, and may be a reasonable alternative for prophylactic platelet transfusions. In the setting of ASCT, Tranexamic Acid may reduce bleeding and further enhance a strategy of therapeutic platelet transfusions where platelets are administered only in the event of active bleeding symptoms.
