Home Treatment

Seek medical care immediately. Call Poison Control. Do not induce vomiting.

Before Calling Emergency
Determine the following information:

     
  • The patient’s age, weight, and condition  
  • Name of product (as well as the ingredients and strength, if known)  
  • The time it was swallowed  
  • The amount swallowed  
  • If the medication was prescribed for the patient

Poison Control, or a local emergency number
See Poison Control centers for telephone numbers and addresses. Take the container with you to the emergency room.

What to expect at the emergency room

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

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