1 A hospitalized patient with renal failure receiving oral aluminium hydroxide was found to have a blood aluminium level of 3124 μg/l (116 μmol/l) .
2 The extremely high aluminium concentration was attributed to the concurrent use of an oral citrate solution which converted the aluminium to a more soluble and absorbable form.
3 The combination of oral aluminium and citrate should be avoided in patients with poor renal function.
