The following precautions should be taken into account to minimise the risk of renal adverse reactions with zoledronic acid

For all patients receiving zoledronic acid:
* Renal function should be measured before each infusion of zoledronic acid
* Patients, especially elderly patients and those receiving diuretic therapy, should be appropriately hydrated before administration of zoledronic acid
* The duration of infusion of zoledronic acid should be at least 15 minutes
* Monitoring of renal function after zoledronic acid infusion should be considered, particularly in at-risk patients such as: those with pre-existing renal dysfunction; those of advanced age; those using concomitant nephrotoxic drugs or diuretic therapy; or those who are dehydrated
* Zoledronic acid should be used with caution when used concomitantly with medicines that could affect renal function

For patients receiving Zometa
* The recommended dose for Zometa in patients with normal renal function is 4 mg, which should be reduced in patients with mild-to-moderate renal impairment
* Zometa for cancer treatment is not recommended for use in patients with creatinine clearance <30 mL/min, and should only be considered for the treatment of hypercalcaemia in cancer patients with severe renal impairment after evaluating the risk and benefits of treatment * In patients who show evidence of renal deterioration during the treatment period, Zometa should be with-held and only resumed when serum creatinine returns to within 10% of baseline MHRA Drug Safety Update Volume 3 Issue 9 April 2010
