  • the time it was swallowed  
  • the amount swallowed

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:

  • Use gastric lavage.  
  • Administer activated charcoal.  
  • Administer a cathartic (a medication used to evacuate the bowels).
