title: Symptomatic hypomagnesemia associated with gentamicin therapy.
abstract: Seven patients (3 females, 4 males) developed symptomatic hypomagnesemia, hypocalcemia, and hypokalemia following gentamicin therapy. The excessive and inappropriate urinary excretion of magnesium and potassium in the presence of subnormal serum concentrations was noted. A significant correlation was found between the total cumulative dose of gentamicin and serum Mg concentration (r = 0.76, p less than 0.05), as well as between the renal wasting of Mg and the total cumulative dose of gentamicin administered (r = 0.89, p less than 0.01). The gentamicin-induced Mg depletion is a very rare but important complication which is most likely to occur when the drug is given to older patients in large doses over extended periods of time.
