Why do I need an acetaminophen level test?
Your provider may order a test if you or your child has symptoms of an overdose. Symptoms may happen as soon as two to three hours after taking the medicine but can take as long as 12 hours to appear.
Symptoms in adults and children are similar and may include:
Nausea and vomiting
Diarrhea
Abdominal pain
Loss of appetite
Fatigue
Irritability
Sweating
Jaundice, a condition that causes your skin and eyes to turn yellow
