Some or all of the following procedures may be performed:

• For swallowed poison
  • Placement of a tube down the nose and into the stomach (a nasogastric tube, or an NG tube) to wash out the stomach (gastric lavage)
  • Activated charcoal administration
  • Endoscopy -- the placement of a camera down the throat to see the extent of burns to the esophagus and the stomach
  • Give IV fluids
  • Admission to the hospital
  • Give an antidote
  • Treat the symptoms
• For inhaled poisons
  • A breathing tube may need to be inserted
  • Oxygen
  • Admission to the hospital or to the intensive care unit
  • Bronchoscopy (inserting a camera down the throat into the airway to evaluate the extent of burns to the airway and lungs)
• For skin exposure
  • Irrigation (washing of the skin), perhaps every few hours for several days
  • Skin debridement (surgical removal of burned skin)
  • Admission or transfer to a hospital that specializes in burn care

Expectations (prognosis)    Return to top

If the patient survives the first 24 hours, survival is likely. Few patients actually die from an antihistamine overdose.
