Chances are, acetaminophen is a mainstay in your medicine cabinet. You use it to ease aches and pains or bring down a fever.
When you follow the instructions on those pill-bottle labels, it's helpful and safe, and it generally doesn't upset the stomach like other pain relievers.
But if you take too much, it can hurt your liver. In extreme cases, it can even cause liver failure.
It’s still fine to use acetaminophen. You just need to know how to do that safely.
