This case report describes a patient with recurrent symptomatic hypomagnesaemia, on the background of advanced ovarian cancer and a high-output ileostomy, who was successfully managed on a daily continuous subcutaneous infusion of magnesium via a syringe pump. There is limited published information on the subcutaneous administration of magnesium and, to our knowledge, this is the first case to report its routine delivery over 24 hours in a syringe pump. This novel but effective approach for administering magnesium can be delivered in the community and can, therefore, prevent repeated hospital admissions for patients with recurrent symptomatic hypomagnesaemia who would otherwise need intravenous replacement.
