Recurrent pulmonary embolism associated with a hemostatic drug: tranexamic acid.

Tranexamic acid (TA) used in a variety of conditions associated with bleeding has been associated with potential thrombotic side effects such as formation of thrombi and pulmonary embolism (PE). We describe a case of a woman with chronic hemoptysis and a history of PE, who recently used TA as a prophylactic measure, which could have resulted in a new episode of PE. Tranexamic acid probably played a contributory role in the development of her second PE.
