Adult patients with an unintentional exposure may be discharged after a 2- to 4-hour observation period if the clinician has no unique concerns regarding the ingested substance (eg, large volume, high concentration, agent with potential for systemic toxicity) and the patient meets all the following criteria:

  • Asymptomatic
  • Clear sensorium
  • Able to ingest oral fluids without difficulty
  • Demonstrates easy speech
  • Reliable
  • Familiar with delayed symptoms and able to return if any occur
