Implications for Patient Care

    • Cytarabine is a pyrimidine antimetabolite. It is labeled for use as a single agent or in combination with other antineoplastic agents for a variety of leukemias including acute and chronic myelocytic leukemia, acute lymphocytic leukemia, and meningeal leukemia. These regimens are labeled for use in both adult and pediatric patients.[5,6,7]
    • Cytarabine is used off-label in adults with Hodgkin disease or undergoing hematopoietic stem cell transplantation. Cytarabine is also used in non-Hodgkin lymphoma.[5,6,7]
    • Refer to national guidelines such as those from the National Comprehensive Cancer Network ( or American Society of Clinical Oncology ( for additional information regarding therapeutic use.


    • Chemotherapy agents, such as cytarabine, pose additional safety risks both for patients and for healthcare workers handling these agents.[5,6]
    • Use additional caution when processing orders for chemotherapy drugs, especially when switching between chemotherapy agents or when processing orders for chemotherapy agents with which staff may be unfamiliar (eg, those not normally prescribed at a specific institution).[5,6]

Alternative Agents & Management

    • The choice of an alternative agent must be patient-specific and based on renal function, liver function, and the neoplasm type and location. No single agent can be substituted for cytarabine.[5,6,7]
    • Consider evaluating the health-care system's total supply of cytarabine before beginning patients on combination chemotherapy regimens containing cytarabine. If adequate supplies are not available, select an alternative regimen.
    • Consult a Hematology/Oncology specialist for patient- and neoplasm-specific recommendations.
    • Refer to the ASHP Guidelines on Managing Drug Product Shortages for more guidance on developing a multidisciplinary plan when the supply must be allocated.
