| Management | The manufacturer recommends avoiding concomitant use of samarium sm 153 lexidronam with chemotherapy or external beam radiation therapy unless benefits are anticipated to outweigh the risks. Moreover, samarium sm 153 lexidronam should not be given after either of these treatments until there has been time for adequate marrow recovery. Caution and close monitoring of bone marrow function are advisable if coadministration with other myelotoxic agents is required. Patients should be advised to contact their physician if they develop signs and symptoms of myelosuppression such as pallor, dizziness, fatigue, lethargy, fainting, unusual bleeding or bruising, or signs of infection such as fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination. | ||||||||
