The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the U.S. use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

Take the container with you to the emergency room.

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

If the patient survives the first 24 hours, recovery is good. Few patients die from an antihistamine overdose.
