Toxic Epidermal Necrolysis, A Serious Side Effect of Tenoxicam Use: A Case Report

Abstract

Tenoxicam, a selective cyclooxygenase (COX)-2 inhibitor, has potent analgesic and anti-inflammatory effects and is frequently used for out-of-hospital pain control. Even though other non-steroidal anti-inflammatory drugs were incriminated in Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) appearance, the literature is scarce regarding this agent. We report a case of tenoxicam-induced toxic epidermal necrolysis, detailing the multidisciplinary approach in a patient presenting skin detachment of 90% of the total body surface area, with concomitant ocular, oral, nasal, and vaginal mucosae involvement. A skin biopsy confirmed the diagnosis. The immediate cessation of the incriminated drug and rapid initiation of systemic steroids, along with topical therapies, and isolation into a specific environmental condition to limit skin infection were the cornerstones of therapeutic management. The patient was discharged with skin hyperpigmentation area and mild anxiety as long-term sequels. This report emphasized that severe or complicated cases should be transferred to a specialized burn center to reduce mortality risk and long-term morbidity.
