I had stevens/johnson syndrome last year. will it come back easier now?

Stevens/Johnson's: Various etiologic factors have been implicated as causes of stevens-johnson syndrome. Drugs most commonly are blamed. The 4 etiologic categories are as follows: infectious drug-induced malignancy-related idiopathic stevens-johnson syndrome is idiopathic in 25-50% of cases. Drugs and malignancies are most often implicated as the etiology in adults and elderly persons.

No: Stevens johnson syndrome (sjs) could return if you are exposed to the same offending agent that caused the original problem. I don't think you are more prone to sjs if you avoid the original causative agent.
