<p>Tranexamic Acid is a synthetic Amino Acid that is incompatible with solutions containing penicillins (eg: Benzyl penicillin). Thrombolytic drugs like Streptokinase &amp; Urokinase antagonise the antifibrinolytic action of Tranexamic Acid. The potential for thrombus formation may be increased by concomitant administration of estrogen containing drugs, like oral contraceptives. Direct admixture of Tranexamic Acid with whole blood should be avoided during Transfusion.</p>
