Ofloxacin: A probable cause of toxic epidermal necrolysis

OBJECTIVE: To report a fatal case of toxic epidermal necrolysis in a man who was treated with oral ofloxacin for epididymitis. CASE SUMMARY: A 75-year-old white man received 23.6 grams of ofloxacin over a 51-day period for epididymitis. He experienced a severe skin reaction diagnosed as toxic epidermal necrolysis. The man died from complications related to toxic epidermal necrolysis. DISCUSSION: Toxic epidermal necrolysis is an infrequent, yet often fatal, severe, systemic, cutaneous disease most often the result of an adverse drug reaction. Fluoroquinolones have rarely been implicated in cases of toxic epidermal necrolysis. A MEDLINE search from 1966 to December 2000 revealed no reports of toxic epidermal necrolysis, erythema multiforme, or Stevens-Johnson syndrome due to ofloxacin therapy. However, a large case-control study included three cases of either Stevens-Johnson syndrome or toxic epidermal necrolysis associated with ofloxacin use, but no details of the cases were given. This report rules out other causes of toxic epidermal necrolysis and implicated ofloxacin in what appears to be an atypical presentation of drug-induced toxic epidermal necrolysis. CONCLUSIONS: There is very little published information regarding ofloxacin-induced toxic epidermal necrolysis. There are a few case reports of other fluoroquinolones that have been associated with toxic epidermal necrolysis. It is hoped that this case report creates awareness that ofloxacin-induced toxic epidermal necrolysis is possible.
