FDA warns of serious rash risk with acetaminophen pain pills

Washington: Tylenol and other painkillers containing the ingredient acetaminophen can cause a potentially deadly skin rash known as Stevens-Johnson Syndrome, U.S. health regulators said on Thursday.

Companies that sell prescription acetaminophen will be required to add a warning about the skin rash to the drug`s package insert, the Food and Drug Administration said.

The agency will also request or encourage companies who sell acetaminophen products over the counter to add a warning about the risk of serious skin reactions.
