Introduction: Tranexamic acid has found extensive application in obstetrics to prevent and treat postpartum hemorrhage (PPH). This case report investigated an infrequent incidence in which seizures were caused by the administration of tranexamic acid. Even though tranexamic acid is generally regarded as safe, it has been associated with the infrequent yet serious side effects of tranexamic acid-induced seizures. This case report was aimed at investigating the infrequent incidence of tranexamic acid-induced seizures in postpartum patients. Case: It was reported that a woman who was 40 weeks pregnant suffered from postpartum seizures after delivery via cesarean section. These seizures occurred after tranexamic acid was administered to treat postpartum hemorrhage (PPH) caused by uterine rupture, which was accompanied by hypocalcemia. Despite not having a history of epilepsy, preeclampsia, or hypertension, the electrocardiogram (EKG) showed a prolongation of the QT interval. A comprehensive diagnostic evaluation, which involved a CT scan of the head and a D-dimer examination, was conducted, revealing no abnormalities. Discussion: Tranexamic acid, a synthetic derivative of lysine, acts as a competitive inhibitor of plasminogen activation, thereby inhibiting the breakdown of fibrin clots.
