<p>While accidental ingestion is unlikely to cause any systemic effects due to poor absorption of chlorhexidine and cetrimide, ingestion of high concentrations could cause irritation of the gastrointestinal mucosa/gastritis. Gastric lavage might be needed. Symptomatic treatment should be employed. If swallowed, wash out mouth, drink plenty of milk or water and seek medical advice. In case of overdose, seek medical attention or contact a poison control centre.</p>
