Postpartum hemorrhage (PPH) remains a significant cause of maternal mortality worldwide. Effective management strategies are crucial to improve outcomes. Tranexamic acid (TXA) has emerged as a critical medical intervention for controlling bleeding in obstetric scenarios, particularly postpartum.

TXA functions as an antifibrinolytic agent, stabilizing blood clots by inhibiting the breakdown of fibrin. This action is vital in situations like PPH, where excessive bleeding can occur due to various factors, including potential fibrinolytic activation.

The landmark WOMAN trial provided strong evidence for TXA's benefit in PPH. It demonstrated that early administration of TXA significantly reduced bleeding-related deaths. Crucially, the effectiveness of TXA is time-sensitive; its greatest benefit is seen when administered within three hours of childbirth. Late administration, however, can be associated with increased mortality, underscoring the importance of prompt treatment.

The recommended dosage for PPH is typically 1 gram of TXA administered intravenously as soon as possible, followed by an additional gram if bleeding persists. While TXA generally does not increase the risk of thrombotic events in obstetric patients, careful consideration of individual patient factors is always warranted.

The World Health Organization (WHO) recognizes TXA as an essential medicine for PPH, advocating for its widespread availability. Tranexamic acid is a powerful tool in the obstetrician's armamentarium, offering a life-saving intervention for women experiencing postpartum hemorrhage. Its inclusion in standard PPH protocols significantly contributes to maternal safety.
