Contact Poison Control for treatment guidance.

Before Calling Emergency
Determine the following information:

     
  • the patient’s age, weight, and condition  
  • the name of the product (ingredients and strengths if known)  
  • 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 person 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:

     
  • Induce emesis.  
  • Administer activated charcoal.  
  • Administer a laxative.  
  • Take a blood sample (venipuncture) to determine the salicylate level in the blood.  
  • Administer fluids (milk, fruit juices or, in severe cases, IV fluids).  
  • Sponge water baths to control fever.  
  • Give other medications as needed.  
  • Treat complications as necessary.

Expectations (prognosis)
The blood level of salicylates determines the outcome. Recovery is likely if the acidic effect of the salicylate can be effectively neutralized. Methyl salicylate (oil of wintergreen) is the most toxic form of the salicylates. Doses of less than 1 teaspoonful have been lethal in small children.
