<p>Sucralfate should only be used with caution in patients with renal dysfunction, due to the possibility of increased aluminium absorption. Sucralfate is not recommended for use in individuals on dialysis. In patients with severe or chronic renal impairment, Sucralfate should be used with extreme caution and only for short-term treatment. Small amounts of aluminium are absorbed through the gastrointestinal tract and aluminium may accumulate. Aluminium osteodystrophy, osteomalacia, encephalopathy and anaemia have been reported in patients with chronic renal impairment. For patients with impairment of renal function, laboratory testing such as aluminium, phosphate, calcium and alkaline phosphatase is recommended to be periodically performed due to excretion impairment. The concomitant use of other aluminium containing medications is not recommended in view of the enhanced potential for aluminium absorption and toxicity. Bezoars have been reported after administration of sucralfate mainly to severely ill patients in intensive care units. The majority of these patients (including neonates in whom sucralfate is not recommended) had underlying conditions that may predispose to bezoar formation (such as delayed gastric emptying due to surgery, drug therapy or diseases that reduce motility) or were receiving concomitant enteral tube feeding.</p>
