Intravenous zoledronic acid: adverse effects on renal function
Zoledronic acid is associated with reports of renal impairment and renal failure, especially in patients with pre-existing renal dysfunction or other risk factors. Renal function should be measured before each dose, and patients should be adequately hydrated before treatment. Renal function monitoring is recommended after use of zoledronic acid in at-risk patients—especially those with pre-existing renal impairment. Use in patients with severe renal impairment is generally not recommended, but may be considered for tumour-induced hypercalcaemia, if the benefits outweigh the risks.
