It has improved efficacy, better tolerability and convenient administration via subcutaneous route, in comparison with bisphosphonates; however, it has been reported to cause severe hypocalcaemia in certain high-risk individuals. We report the case of a 71-year-old man with a history of haemodialysis-dependent end-stage renal disease who developed severe hypocalcaemia with electrocardiographic changes after being started on denosumab for prevention of SREs from a recently diagnosed metastatic prostate cancer. He was admitted to the hospital for close monitoring and received multiple doses of intravenous calcium gluconate, along with haemodialysis with high calcium bath. We aim to highlight the risk of severe, life-threatening hypocalcaemia associated with denosumab and to recognise patients at risk of developing this serious adverse effect, so that prompt treatment and preventive strategies can be implemented.<\/jats:p>","DOI":"10.1136\/bcr-2017-224068","type":"journal-article","created":{"date-parts":[[2018,5,30]],"date-time":"2018-05-30T07:35:59Z","timestamp":1527665759000},"page":"bcr-2017-224068","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Denosumab
