Drug Interactions between cytarabine liposomal / daunorubicin liposomal and topotecan

MONITOR: The use of topotecan with other cytotoxic agents is likely to result in greater myelosuppression due to additive or synergistic pharmacologic effects. Severe neutropenia and neutropenic sepsis resulting in death were reported with topotecan and cisplatin.

MANAGEMENT: Caution is advised if topotecan is used with other cytotoxic agents. Dosage reductions may be required, and bone marrow function should be closely monitored. Patients should be advised to contact their physician if they develop signs and symptoms of myelosuppression such as pallor, dizziness, fatigue, lethargy, fainting, easy bruising or bleeding, or signs of infection such as fever, chills, sore throat, body aches, and other influenza-like symptoms.

MONITOR: The concomitant or sequential administration of multiple antineoplastic agents may result in additive toxicities, particularly in the bone marrow, gastrointestinal tract and heart.

MANAGEMENT: Close clinical and laboratory monitoring for hematologic and nonhematologic toxicities are recommended when antineoplastic agents are administered concurrently or during close intervals. Dosing adjustments may be necessary. The manufacturers' recommendations and institutional protocols for dosage, treatment regimens, monitoring, and management of toxicities should be consulted.
