The US Food and Drug Administration (FDA) has added acetaminophen to the list of pain relievers that may in rare cases trigger life-threatening skin reactions.
The FDA issued a warning in August that pain and fever reducer acetaminophen may cause Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), or acute generalized exanthematous pustulosis (AGEP), conditions that may be fatal, based on a review of the literature and the FDA Adverse Event Reporting System (FAERS) database (http://1.usa.gov/13fvMbR). These conditions may emerge with flu-like symptoms, a rash, blisters, or shedding of layers of skin after a first or repeat dose of acetaminophen, the agency notes.
