Symptomatic hypocalcaemia after treatment with zoledronic acid in a patient with multiple myeloma

Abstract
Zoledronic acid is a long-acting bisphosphonate used to decrease skeletal events in patients with multiple myeloma and bony metastasis. It is known to lead to asymptomatic hypocalcaemia, but symptomatic hypocalcaemia after its use is rarely reported [1]. We report a patient with multiple myeloma who developed symptomatic hypocalcaemia with zoledronic acid.
