Rifampicin-Induced Pulmonary Embolism: A Rare Side Effect.
Overview
abstract
Rifampicin is an established and effective antibiotic and a gold standard in treating tuberculosis (TB). Venous thromboembolism (VTE) events are a rare side effect of rifampicin, which has been reported in a few case reports. The exact mechanism is yet not clear, however, could include immunological and hematological causes. Here, we report a 56-year-old male who presented with pulmonary embolism (PE) three weeks after initiating rifampicin for latent TB management. Comprehensive investigations were done to rule out any other causes of thrombosis, especially malignancy, however, all tests were negative. The patient was treated with anticoagulant agents and rifampicin was switched to isoniazid after rifampicin discontinuation. He remained stable upon discharge and follow-up.
