Phase 3 (72-96 h after ingestion), is also called the hepatic phase. Patients may have continued nausea and vomiting, abdominal pain, and a tender hepatic edge. Hepatic necrosis and synthetic dysfunction manifest as jaundice, coagulopathy, hypoglycemia, and hepatic encephalopathy. Acute renal failure develops in some critically ill patients. Death from multiorgan failure may occur.
