Once swallowed, acetaminophen is rapidly absorbed from the stomach and intestines and can achieve significant levels in the blood within 30 minutes. The main toxic effects take two forms: 1  Liver damage: One of the substances produced by the breakdown of acetaminophen binds to liver cells, damaging them. Severe damage can lead to liver failure. 2  Damage to red blood cells: One of the substances produced by the breakdown of acetaminophen binds to red blood cells.
