It's difficult to prevent an initial attack of Stevens-Johnson syndrome because you don't know what will trigger it. However, if you had Stevens-Johnson syndrome once, and your doctor determined that it was caused by medication, be sure to avoid that medication and others in the same class to prevent another attack. If the herpes virus caused your reaction, you may need to take daily antiviral medications to prevent a recurrence.

A recurrence of Stevens-Johnson syndrome is usually more severe than the first episode and, in many cases, it can be fatal.
