The FDA has issued a warning on the potential of severe allergic reactions from both prescription and over the counter pain medications containing acetaminophen. Pain medications containing acetaminophen have been found to be a possible cause of a rare and serious skin condition known as Stevens-Johnson syndrome.
The allergic reaction begins with flu-like symptoms and progresses to a red or purple rash often seen on the facial area which is quite painful and may lead to blistering eventually resulting in the outer layer of skin to peel leaving large exposed areas which are at risk of infection.
The condition can occur even if you have previously taken acetaminophen products with no problem. If you develop any type of skin rash after using a pain medication, it’s best to stop and discuss it with your doctor.
