Question: why rifampicin causes hemolytic anemia?
Answer: This shows that rifampicin may stimulate the production of autoantibodies (aab) and/or drug‐dependent antibodies (ddab), and that the resulting haemolytic syndrome bears similarities with AIHA and AHTR. Rifampicin has been reported to cause haemolysis due to the production of drug‐dependent antibodies (ddab).
