VePesid (etoposide) should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Severe myelosuppression with resulting infection or bleeding may occur. Patients being treated with VePesid must be frequently observed for myelosuppression both during and after therapy. Myelosuppression resulting in death has been reported. Dose-limiting bone marrow suppression is the most significant toxicity associated with VePesid therapy. Therefore, the following studies should be obtained at the start of therapy and prior to each subsequent cycle of VePesid: platelet count, hemoglobin, white blood cell count, and differential. The occurrence of a platelet count below 50,000/mm 3 or an absolute neutrophil count below 500/mm 3 is an indication to withhold further therapy until the blood counts have sufficiently recovered.
