Adrenal crisis after first infusion of zoledronic acid: a case report.

Patients with Addison's disease are at greater risk of having reduced bone mineral density and hip fractures and are thus more likely to receive a bisphosphonate than their peers. Potent intravenous bisphosphonates could provoke an acute phase reaction. An 80-year-old female with Addison's disease received her first infusion of zoledronic acid for osteoporosis at our outpatient clinic around noon.
