Drugs affecting serum magnesium concentration

: Several oral or intravenous drug administrations can cause abnormalities in serum magnesium concentration. Most of drug-induced hypomagnesemia derives from a loss of the mineral in the urine by facilitating renal secretion. Hypermagnesemia can occur by a direct intake of drugs including magnesium, especially in patients with renal insufficiency. Frequent check of serum magnesium concentration will be needed to monitor these abnormalities.
