Antituberculosis Therapy (ATT) Induced Thrombocytopenia: A Case Report

Thrombocytopenia is a rare adverse effect seen with anti-tubercular drugs. We report an 80 year old male with tuber-cular right pleural effusion, on Category I Anti-tubercular therapy (ATT) for 3 weeks who presented with melena and epistaxis. On evaluation, he had thrombocytopenia which was found to be rifampicin-induced. ATT was restarted with-out rifampicin and there were no bleeding episodes. Though, rifampicin is well tolerated, but on rare occasions it can cause thrombocytopenia.
