Mild haemolysis associated with flu-syndrome during daily rifampicin treatment--a case report.

We describe a woman with the 'flu' like syndrome and haemolysis whilst on a supervised daily rifampicin regimen for the treatment of pulmonary tuberculosis. Although these are known complications of rifampicin therapy, they often occur when therapy is intermittent or interrupted. Hence the case we describe is unique and is the first of its kind to be reported in Singapore.
