Outlook

Recovery is likely if the proper treatment is given and the dose of aspirin taken is not too high.

Signs and symptoms as well as prognosis in chronic aspirin poisoning are less predictable. In the case of acute aspirin poisoning, symptom severity can be predicted by the dose ingested.

• Less than 150 milligrams of aspirin per kilogram of body weight (mg/kg) - no symptoms to mild toxicity
  
  
• Ingestions of 150-300 mg/kg - mild to moderate toxicity
  
  
• Ingestions of 300-500 mg/kg - serious toxicity
  
  
• Greater than 500 mg/kg - potentially lethal
