What is the significance of a Tylenol level of more than 400 in an OD?

Answer 1

Instead of helping your body by introducing an agent for healing, you are in fact causing injury and adding stress to your system. Why would you ever do that to yourself? If you want attention, succeed at something. Don't hurt yourself.

Answer 2

Sever overdosage may produce nausea, vomiting, perspiration, and general discomfort. Massive overdosage may produce damage to live, kidneys, and central nervous system. Potentially toxic single dose: 10 - 15 grams; 25 grams is potentially fatal.
