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.  
  • Use gastric lavage.  
  • Monitor vital signs (temperature, pulse, rate of breathing, blood pressure).  
  • Maintain the airway.  
  • Replace fluids if appropriate.  
  • Treat the symptoms.

Expectations (prognosis) 
The amount swallowed and time before treatment begins usually determine the final outcome. The sooner treatment is started, the greater the chance of a positive outcome.
