Recombinant erythropoietin overdose.

Deliberate self-administration of recombinant human erythropoietin (rHuEpo) in a patient without anemia has never been documented. The case of a 62-year-old man who worked in an allied health care field and surreptitiously injected the drug, causing his hematocrit to increase to a dangerously high level is presented. Resultant complications of the misuse of erythropoietin in this patient included worsening hypertension, exacerbation of chronic lung disease and development of new onset angina. Medical management consisted of endotracheal intubation with mechanical ventilation, intravenous hydration, and serial phlebotomy. The unusual possibility of erythropoietin abuse must be added to the differential diagnosis with a patient with unexplained polycythemia. This case highlights the potential abuse of biological growth factors that may mask medical conditions.
