Zoledronic acid injection is used to treat hypercalcemia (high levels of calcium in the blood) that may occur in patients with some types of cancer. It is also used to treat a cancer called multiple myeloma (tumors formed by the cells of the bone marrow) or certain types of bone metastases (the spread of cancer to the bone).
Zoledronic acid injection is also used to treat Paget's disease of the bone in men and women. It is also used in men with osteoporosis and in women with osteoporosis who have gone through menopause. This medicine is used to reduce the risk of having more fractures in patients who have had a recent hip fracture.
