Immediate GI decontamination is the priority in xylitol ingestion, followed by inpatient glucose monitoring and hepatic support. Dogs that have emesis induced are less likely to develop hepatopathy than those in which emesis is not induced, making early decontamination a critical intervention.Journal of Vete…
Induce emesis as soon as possible after ingestion if the dog is not yet symptomatic.MSD Vet Manuals Dogs that presented with clinical signs prior to veterinary evaluation were 1.95 times more likely to develop hepatopathy than those without pre-presentation signs, reinforcing that speed of decontamination matters.Journal of Vete… Activated charcoal is not reliably effective for xylitol and is not a standard recommendation for this toxicosis.MSD Vet Manuals
After decontamination, hospitalize for intravenous (IV) glucose supplementation and serial blood glucose (BG) monitoring. Hypoglycemia is defined at a BG ≤ 3.3 mmol/L (60 mg/dL), and BG drops in most dogs following presentation — the initial BG at presentation does not reflect the nadir.Journal of Vete… Dextrose supplementation should be titrated to maintain euglycemia.MSD Vet Manuals
Monitor potassium closely: hypokalemia on presentation is independently associated with development of hepatopathy, and the clinical syndrome includes hypokalemia and hypophosphatemia alongside hypoglycemia.Journal of Vete…+1 Electrolyte abnormalities should be corrected with IV supplementation as needed.Topics in Compa…
Hepatic injury develops in approximately 49.5% of dogs following xylitol ingestion, and liver enzyme monitoring (alanine aminotransferase, total bilirubin) is essential throughout hospitalization.Journal of Vete…+1 Dogs with elevated liver values had a significantly lower nadir BG, so the degree of hypoglycemia correlates with hepatic injury risk.Journal of Vete… Hepatic support should be initiated in dogs showing enzyme elevation.Topics in Compa… Acute hepatic failure can be associated with coagulopathy, which warrants monitoring and management if present.Veterinary Clin…
Prognosis is excellent for dogs that develop uncomplicated hypoglycemia without hepatic failure. All dogs in one cohort survived to discharge, and 158 of 192 were confirmed alive at 28 days (the remainder were lost to follow-up).Journal of Vete… Dogs developing hepatic failure carry a more guarded prognosis, though no dog in a more recent cohort of 95 developed evidence of hepatic failure.Journal of Vete…+1
