Tranexamic Acid in Pediatric and Emergency Medicine: Evidence Review and Practical Applications.

Abstract

Tranexamic acid (TXA) is an antifibrinolytic medication that helps stabilize clots and reduce bleeding. Although FDA approval is limited, it has become widely used off-label in pediatric and emergency medicine. Evidence shows that TXA decreases blood loss, reduces transfusion requirements, and may improve survival in trauma. It has also been beneficial in pulmonary hemorrhage, post-tonsillectomy bleeding, epistaxis, abnormal uterine bleeding, and secondary postpartum hemorrhage. TXA is generally safe and well tolerated; common side effects include headache and abdominal discomfort, while serious events such as seizures or allergic reactions are rare. Its favorable safety profile and broad applicability make TXA a valuable tool for frontline clinicians managing pediatric bleeding emergencies. More pediatric-specific trials are needed, but current evidence supports TXA as both effective and practical in a variety of emergency settings.
