INTRODUCTION
Magnesium (Mg) is the fourth most plentiful mineral in the body, having the role of cofactor for enzymatic reactions (1-3). The normal range of Mg concertation of serum in humans is 1.8-2.3 (4). Magnesium sulfate is the drug of choice for the prevention and treatment, and recurrence management of convulsions in eclampsia and pre-eclampsia and it is an FDA-approved indication in hypomagnesemia management (5-7). Considering the elevated use of Mg in the management of different conditions, the safety of therapy needs more research. However, electrocardiographic (ECG) and electrophysiological outcomes of intravenous (IV) Mg injection have been assessed in animal research (8). We report a case of Mg Sulfate toxicity managed with hemodialysis, with clinical improvement and hospital discharge.
