Stevens-Johnson Syndrome & TEN for ICU Nurses 2026 — When the Skin Sloughs

Part of the ICU Emergencies Hub — browse every related guide in one place.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are the same disease at different severities: a catastrophic, usually drug-triggered reaction in which the skin and mucous membranes blister and peel away in sheets. Losing the skin barrier turns a patient into something physiologically close to a major burn — leaking fluid, unable to hold heat, and wide open to infection. These patients often land in a burn unit or ICU, and the nursing care is meticulous and high-stakes. This guide covers what to recognize, the drug link, and the barrier, fluid, and mucosal care the nurse manages.

What's happening to the skin

In SJS/TEN the immune system mounts a violent reaction, most often to a medication, that kills the keratinocytes holding the epidermis together. The top layer of skin dies and separates from the layer beneath, so it blisters and then peels away, leaving raw, weeping dermis exposed — the same defenseless surface a deep burn creates. The mucous membranes are involved too, which is part of what distinguishes these from milder rashes: painful erosions in the mouth make eating and drinking impossible, eye involvement threatens vision, and the genital and airway mucosa can be affected. The extent of skin detachment defines the severity and correlates with mortality, which is why the total body-surface-area estimate matters clinically.

Recognizing it early

It often begins deceptively, with a few days of fever, sore throat, malaise, and stinging eyes before the skin declares itself — so a new painful rash in someone recently started on a high-risk drug deserves a hard look. The rash is typically painful (not just itchy), spreads, and develops dusky or target-like lesions that blister. A key bedside finding is the Nikolsky sign: gentle lateral pressure on the skin causes the top layer to shear off, showing how loosely it's now attached. Mucosal erosions — crusted, bleeding lips, mouth ulcers, red painful eyes — alongside the skin findings point strongly toward SJS/TEN rather than a benign drug rash.

The drug link — and stopping it fast

The great majority of cases are triggered by medications, typically started days to a couple of weeks earlier. Common culprits include certain antibiotics (notably sulfonamides), several antiseizure/mood drugs (such as lamotrigine, carbamazepine, and related agents), allopurinol, and NSAIDs among others. The most impactful single action — and one the whole team, including the nurse reviewing the med list, contributes to — is identifying and stopping the suspected drug immediately, because continuing it worsens outcomes. That drug then goes on the allergy list in bold; a future re-exposure could be fatal.

Burn-style supportive care — the heart of nursing

There's no magic cure; survival hinges on supportive care done well, and it is nursing-intensive. Fluid and electrolyte management replaces what leaks through the denuded skin (though usually needing less than an equivalent burn). Temperature regulation matters because patients can't hold heat through missing skin, so the room is kept warm. Wound care is meticulous and gentle to protect the raw dermis and prevent infection — and infection, not the skin loss itself, is a leading cause of death, so scrupulous asepsis and vigilance for sepsis are central. Pain control is a priority for a condition that is agonizing. Nutrition supports healing when the mouth is too raw to eat. And eye care is urgent and ongoing — ophthalmology involvement early, with lubrication and care to prevent the scarring that can cause permanent vision loss. Mouth care keeps the oral erosions clean and as comfortable as possible.

The nursing bottom line

SJS and TEN are a spectrum of severe, drug-triggered skin failure in which the epidermis dies and peels, taking the mucous membranes with it and leaving a patient as vulnerable as a major burn victim. Recognize the pattern — a prodrome of fever and malaise, a painful spreading rash with dusky or target lesions, mucosal erosions, and a positive Nikolsky sign — especially soon after a high-risk drug. The most important treatment is stopping the culprit medication immediately and flagging it forever. Everything else is burn-style supportive care: fluids, warmth, gentle sterile wound care, infection surveillance, pain and nutrition support, and urgent eye and mouth care. Done meticulously by the bedside nurse, that support is what these patients survive on.
