title: Intravascular haemolysis in a patient on ceftriaxone with demonstration of anticeftriaxone antibodies.
abstract: Drug-induced haemolytic anaemia can be life threatening. We report a case of ceftriaxone-induced severe haemolytic anaemia in a previously healthy 68-year-old woman. The patient had a positive direct antiglobulin test (anti-C3d positive, anti-immunoglobulin G negative). Serological tests showed ceftriaxone-specific antibodies. The patient recovered after cessation of the drug. This complication may cause milder anaemia and thus be poorly recognized.
