Reactions can be dose-dependent and/or Idiosyncratic And the problem is the fact is, often times, when the drugs have been taken The patient might not even present with symptoms and that is scary You really need to make sure that you take a proper history Psychological evaluation is absolutely important or psychiatric evaluation We will talk about that in a second. Injury resolves with removal of offending drug The problem with that is the fact that when you remove the offending drug, because it might caused so much damage to your liver, What's the repair process called? The repair process is called fibrosis. So you might actually have an increased amount of fibrosis. depositing the liver, ugh, and might actually look rather Cirrhotic. Transplantation for fulminant liver failure. our focus acetaminophen toxicity is important.
