  • 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:

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

Expectations (prognosis)

  • Mild       o The patient can be aroused.       o No further treatment will probably be necessary.  
  • Moderate       o The patient cannot be aroused.       o Breathing is normal.       o Other life signs (pulse, skin color, and so on) are normal.       o Recovery will probably occur within 24 to 48 hours with proper care.  
  • Severe       o The patient cannot be aroused.       o Breathing and other life signs may be abnormal.       o Recovery will probably occur within 3 to 5 days, depending on the amount swallowed.
