<p>Patients must be appropriately hydrated prior to administration of Zoledronic Acid. This is especially important in the elderly and for patients receiving diuretic therapy. Adequate hydration can be achieved by the patient drinking two glasses of fluid (such as water) before and after the infusion. Pre-existing hypocalcaemia must be treated by adequate intake of Calcium and Vitamin-D before initiating therapy with Zoledronic Acid. Other disturbances of mineral metabolism must also be effectively treated (e.g. diminished parathyroid reserve, thyroid surgery, parathyroid surgery, intestinal Calcium malabsorption). Physicians should consider clinical monitoring for these patients.</p>
