Zoledronic acid " (Zoliring) is used to treat high levels of calcium in the blood that may be caused by certain types of cancer. Zoledronic acid (Zoliring) is also used along with cancer chemotherapy to treat bone damage caused by multiple myeloma [cancer that begins in the plasma cells (white blood cells that produce substances needed to fight infection)] or by cancer that began in another part of the body but has spread to the bones."
