Bottles of Tylenol will soon come with a red labeled cap urging users to pay attention to warnings.
Taking too much of the drug can cause liver damage and even be fatal. Overdoses send tens of thousands of people to emergency rooms in the U.S. each year.
While products already warn consumers in small print, starting in October new caps on bottles of extra strength Tylenol will alert consumers that the product contains acetaminophen and will instruct them to read the warning label.
Other Tylenol products will phase in the new caps over the coming months.
