Known sensitivity to TXA; 2. Recent craniotomy (past 30 days); 3. Active cerebrovascular bleed; 4. Active thromboembolic disease (such as deep vein thrombosis, pulmonary embolism, cerebral thrombosis, ischemic stroke, or acute coronary syndrome); 5. Acute promyelocytic leukemia taking all-trans retinoic acid for remission induction, or 6. Continuing use of a combined hormonal contraceptive and or combined hormonal replacement therapy (including combined hormonal pill, patch, or vaginal ring). 8. Has the following risk factors for thromboembolic disease: 1. Known medical history of congenital or acquired thrombophilia such as, but not limited to patients with: - Sickle cell disease; - Nephrotic syndrome; - Factor V Leiden; - Prothrombin gene mutation; - Protein C or S deficiency; - Antithrombin III deficiency; - Antiphospholipid syndrome. 2. Stage IV malignant neoplasm; 3. Neurologic paresis, partial paralysis, or paralysis; 4. Pacemaker; 5. History of pulmonary embolism, deep vein thrombosis, cerebrovascular accident, or rental venous/arterial occlusion; 9. History of or current seizure disorder. 10. Patients with myeloproliferative disorders. 11. Body Mass Index (BMI) >40. 12.
