Symptoms of alcohol poisoning in babies can include difficulty breathing, reduced activity and seizures. Some studies have found a risk for low blood sugar. The long-term effects on the baby are also unclear, and a one-time event may not cause problems.
In adults severe symptoms of ethanol intoxication may develop after ingestion of 1 to 1.5 mL/kg (50-100 mL) of pure alcohol. Death is usually associated with levels >80 to 90 mmol/L, but the lethal level may be much higher for chronic ethanol users.
