The exact cause of Stevens-Johnson syndrome is unknown in 25 to 30% of cases. In those cases in which the cause can be determined, it is believed to be related to an adverse allergic drug reaction. Almost any drug--but most particularly sulfa drugs--can cause Stevens-Johnson syndrome. The allergic reaction to the drug may not occur until 7-14 days after first using it. Stevens-Johnson syndrome can also be preceded by a viral infection, such as herpes or the mumps. In rare cases, Stevens-Johnson syndrome may be caused by an illness or bone marrow transplantation.
