Levofloxacin and furazolidone induced toxic epidermal necrosis

Toxic epidermal necrolysis (TEN), also known as Lyell's syndrome, is a severe cutaneous drug reaction with a high mortality. Immune response is the possible cause in its pathogenesis. Levofloxacin is one of the most commonly used quinolones and has been reported to cause of TEN. On the other hand, furazolidone was proposed to augment the action of immediate hypersensitivity of levofloxacin by its cytotoxic effect and by the generation of free radicals. Here, we present a case of TEN where, levofloxacin and furazolidone were the probable cause of these adverse drug reactions.
