ALKERAN for Injection is indicated for the palliative treatment of patients with multiple myeloma for whom oral therapy is not appropriate.
ALKERAN for Injection may cause local tissue damage should extra vasation occur, and consequently it should not be administered by direct injection into a peripheral vein. It is recommended that ALKERAN for Injection be administered by injecting slowly into a fast-running IV infusion via an injection port, or via a central venous line (see DOSAGE AND ADMINISTRATION: Administration Precautions).
In all instances where the use of ALKERAN for Injection is considered for chemotherapy, the physician must evaluate the need and usefulness of the drug against the risk of adverse events. Melphalan should be used with extreme caution in patients whose bone marrow reserve may have been compromised by prior irradiation or chemotherapy or whose marrow function is recovering from previous cytotoxic therapy.
