Hand Sanitizer Ingestion: Toxicity, Risks, and Emergency Response

Hand Sanitizer Is Not for Drinking

Most contain 60–95% ethanol or isopropanol – far higher than beverages (beer 4–6%, wine 12–15%, spirits 40%). Even small volumes can cause severe toxicity, especially in children.

Acute Effects by Dose

Amount (70% sanitizer)	Child (10 kg)	Adult (70 kg)
1 pump (~2.5 mL)	Mild intoxication risk	Unlikely significant
1 oz (30 mL)	Severe poisoning (BAC ~200 mg/dL)	Mild-moderate intoxication
2 oz (60 mL)	Potentially fatal	Significant intoxication

Clinical Manifestations

• CNS: Confusion, ataxia, slurred speech, lethargy, coma, seizures.
• GI: Nausea, vomiting, abdominal pain, gastritis.
• Metabolic: Hypoglycemia (esp. children), metabolic acidosis (isopropanol → acetone).
• Respiratory: Depression, aspiration risk.
• Ocular: Splash → corneal abrasion, chemical conjunctivitis.

Special Risks

• Children: Smaller volume/kg, immature metabolism, higher brain:body ratio → severe CNS depression, hypoglycemia.
• Methanol contamination: Some recalled products contained methanol → blindness, metabolic acidosis, death.
• Denaturants: Bittering agents (denatonium) don't prevent ingestion by determined individuals.

Emergency Response

1. Call Poison Control (US: 1-800-222-1222) or EMS.
2. Do NOT induce vomiting (aspiration risk).
3. If alert: give water/milk to dilute.
4. Monitor vital signs, glucose.
5. Hospital: IV fluids, glucose, airway support, hemodialysis (rare, for massive isopropanol/methanol).

Prevention

• Store out of sight/reach of children.
• Use pump bottles, not open cups.
• Supervise use; teach "hands only."
• Discard recalled products (FDA list).
