Chlorpromazine-associated haemolysis in anorexia nervosa.

Chlorpromazine therapy in a patient with anorexia nervosa was associated with haemolytic anaemia. In vitro red cell findings included an increased degree of red cell autohaemolysis and a chlorpromazine-dependent Heinz body formation both corrected with exogenous glucose. Activities of red cell enzymes involved with the glycolytic pathway or glutathione metabolism were normal.
