Strom et al reviewed Medicaid billing data from 1980-1984 in Michigan, Minnesota, and Florida to determine the incidence of Stevens-Johnson syndrome; the incidence rates were 7.1, 2.6, and 6.8 cases per million population per year, respectively. [30]

Cases tend to have a propensity for the early spring and winter.

For overlapping SJS and TEN, oxicam NSAIDs (piroxicam, meloxicam, tenoxicam) and sulfonamides are most commonly implicated in the United States and other western nations. [26]

SJS occurs with a worldwide distribution similar in etiology and occurrence to that in the United States. However, a study from Germany reported only 1.1 cases per 1 million person-years.

In contrast to the drugs most often implicated in western nations, allopurinol is the most common offending agent in Southeast Asian nations, including Malaysia, Singapore, Taiwan, and Hong Kong. [26]
