  • * life-threatening

  • * hospitalisation

A 40.5-year-old man developed hypophosphataemia and osteomalacia following treatment with ferric carboxymaltose and iron sucrose for microcytic anaemia. Additionally, zoledronic acid and unspecified glucocorticoid contributed in osteomalacia [not all dosages and routes stated].

He had been receiving calcium and vitamin D supplementation, along with maintenance therapy of...
