Before Calling Emergency 
Determine the following information:

  • 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 
They will instruct you if it is necessary to take the patient to the hospital. 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 
Some or all of the following procedures may be performed:

  • Administer activated charcoal.  
  • Administer a laxative.  
  • Use gastric lavage.  
  • Treat the symptoms.

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