"Acetaminophen overdose is one of the most common poisonings worldwide," according to the National Institutes of Health."

"Taking too much of this pain reliever can lead to liver failure or death."

"The FDA has set the recommended maximum for adults at 4,000 milligrams per day. It's easier to reach this limit than you might think; one gel tablet of Extra Strength Tylenol, for example, contains 500 mg."

"Consumers should not take more than the prescribed dose of any medication that contains acetaminophen, according to the FDA, and should avoid taking more than one acetaminophen product at a time. Drinking alcohol while taking acetaminophen also puts you at risk."
