The appropriate timeframe for administering tranexamic acid (TXA) is within 3 hours after an injury. This protocol is based on clinical studies that have demonstrated the effectiveness of TXA in reducing mortality due to traumatic hemorrhage when administered early. Specifically, TXA is most beneficial when given promptly after the onset of hemorrhage, which is defined within that critical 3-hour window. Administering TXA during this timeframe enhances its ability to inhibit fibrinolysis and stabilize clot formation, ultimately improving outcomes for patients with significant bleeding.

While administering TXA before 1 hour is certainly beneficial and ideal, the evidence supports the broader window of up to 3 hours to ensure that patients who may require this intervention receive it in a timely manner, even if they are not able to receive it immediately. The options surrounding administration within 24 hours do not align with the urgent need to address acute bleeding scenarios, where early intervention is key to patient survival.
