Which medication is known to adversely affect liver function?

Acetaminophen is known to adversely affect liver function, particularly when taken in excessive doses. It is metabolized in the liver, and while it is generally safe at recommended doses, overuse can lead to a toxic buildup of metabolites. This accumulation can result in liver damage, including acute liver failure, especially in individuals with preexisting liver conditions, or those who consume alcohol regularly.

In contrast, although other medications like ibuprofen and aspirin can have effects on the body, they are less likely to cause direct liver toxicity compared to acetaminophen. Amoxicillin, an antibiotic, is not primarily associated with liver damage, although it can lead to liver enzyme elevation in some cases. Thus, acetaminophen stands out as a medication with a well-documented risk for liver toxicity when misused.
