Doctor, please how much of tylenol overdose in mg or ml within 24hrs is considered overdose in infant weigh 8kg that can cause liver failure? thank u.

Amount vs weight: A single dose of 150 mg/kg or here 150X8=1200 mg will produce liver damage. A blood acetomenophen level of over 150 mcg/ml at 4 hrs from ingestion or 5 @ 24 hrs suggests probable damage. The same dose spread out evenly over 24 hrs may not be toxic. Blood tests are done to determine level of toxicity at any point that overdose is suspected.
