Risk of aluminium accumulation in renal impairment
May affect the absorption of concomitant oral drugs
The formation of bezoar has been reported when sucralfate and enteral feeds have been given too closely together.
Periodically perform laboratory testing of aluminium, phosphate, calcium and alkaline phosphatase in patients with renal impairment due to excretion impairment. 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.
Sucralfate must not be inadvertently administered intravenously as it may induce fatal complications such as pulmonary and cerebral emboli and aluminium intoxication.
Pregnancy and Lactation
Sucralfate is considered safe to use during pregnancy.
The manufacturer recommends sucralfate is not used in pregnancy unless clearly needed. Teratogenicity studies in mice, rats and rabbits at doses up to 50 times the human dose have revealed no evidence of harm to the foetus. The absorption of sucralfate from the gastrointestinal tract is negligible (Schaefer 2015). No adverse effects during pregnancy are anticipated.
There is consensus, that sucralfate and antacids may be used during all phases of pregnancy and have been widely prescribed without evidence of adverse effects. The potential foetal toxicity of sucralfate relates to its aluminium content though there is no evidence that normal doses of aluminium-containing medications such as sucralfate present a risk to the foetus in women with normal renal function (Briggs 2015).
Use sucralfate with caution during breastfeeding.
The manufacturer advises caution if sucralfate is used when breastfeeding. At the time of writing there is no information on the use of sucralfate during breastfeeding. Minimal excretion of sucralfate into breast milk should be expected as only small amounts of this drug are absorbed systemically.
It is strongly recommended that the UK National Poisons Information Service be consulted on cases of suspected or actual overdose where there is doubt over the degree of risk or about appropriate management.
