Acute oral toxicity (LD50) in mice is >8000 mg/kg. There is limited experience in humans with overdosage of sucralfate. Sucralfate is only minimally absorbed from the gastrointestinal tract and thus risks associated with acute overdosage should be minimal. In rare reports describing sucralfate overdose, most patients remained asymptomatic.
For the short-term treatment (up to 8 weeks) of active duodenal ulcer, as well as maintenance therapy for duodenal ulcer patients at reduced dosage (1 gram twice a day) after healing of acute ulcers. Also used for the short-term treatment of gastric ulcer.
