Overview
Introduction
Fever followed by painful skin, dusky or purpuric macules, blistering, epidermal sloughing, and erosions of the mouth, eyes, or genitals is an emergency pattern.
Fever followed by painful skin, dusky or purpuric macules, blistering, epidermal sloughing, and erosions of the mouth, eyes, or genitals is an emergency pattern. This is epidermal necrolysis (EN), historically described as Stevens-Johnson syndrome (SJS), SJS/TEN overlap, or toxic epidermal necrolysis (TEN). The reaction can destroy the skin barrier over hours to days, causing fluid loss, temperature instability, infection risk, severe pain, and permanent ocular injury. A nurse should treat the suspected medication as a possible culprit immediately, escalate the finding, and prepare for transfer to a specialized burn, dermatology, or intensive care center. Biopsy and specialist confirmation refine the diagnosis; neither should delay withdrawal of the suspected drug.
