Ticlopidine Induced Anemia and Agranulocytosis

A 63-year-old man with a history of transient ischemic attack had been treated with ticlopidine for 2 months. He presented with a 6-day history of fever, sore throat, and generalized weakness. Agranulocytosis and anemia due to ticlopidine was diagnosed, and the ticlopidine was discontinued. Broad-spectrum antibiotics and granulocyte colony stimulating factor were administered. The recovery of the granulocyte count and an improvement of the clinical condition were noted on the 6th day of the admission.
