Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are rare but life-threatening medical emergencies. These severe allergic reactions typically begin with flu-like symptoms and can rapidly progress to widespread skin and mucous membrane damage. Identifying early warning signs is crucial for timely diagnosis and treatment, especially before misdiagnosis occurs.
What is SJS and TEN?
- Stevens-Johnson Syndrome (SJS) affects less than 10% of the body’s surface area and causes skin blistering, ulcers, and painful mucous membrane involvement.
- Toxic Epidermal Necrolysis (TEN) is a more severe form, where more than 30% of the skin peels off, often leading to critical complications.
| Condition | Skin Involvement | Severity |
|---|---|---|
| SJS | Less than 10% | Serious but manageable |
| TEN | More than 30% | Critical and life-threatening |
Why Is SJS Often Misdiagnosed?
In the early stages, SJS and TEN are often mistaken for:
- Measles or viral rash
- Dengue fever
- Severe flu or allergic reactions
- Eye infections or conjunctivitis
Because of this, diagnosis is frequently delayed. However, early symptoms provide important clues.
What Are the Early Warning Signs?
If someone develops any of the following symptoms — especially after starting a new medication — urgent action is needed:
- Painful red or purple skin rashes that may spread
- Sudden onset of eye redness, irritation, or difficulty opening eyes
- Swollen lips, blisters in the mouth or genital areas
- Fever, fatigue, sore throat
- Peeling or detachment of skin within a few days
These symptoms often appear within 1–3 weeks of starting a new medication. The skin may feel like it is burning or becoming tender.
What Medications Commonly Trigger SJS or TEN?
Several drugs are known to be associated with Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN). The most common include:
- Antibiotics: Sulfa drugs (like Cotrimoxazole), Penicillins
- Anticonvulsants: Phenytoin, Carbamazepine, Lamotrigine
- Painkillers: Paracetamol combinations, NSAIDs like Ibuprofen or Nimesulide
- Anti-gout drugs: Allopurinol, Febuxostat
- Some herbal or over-the-counter medicines can also trigger reactions in sensitive individuals
What Should You Do If You Suspect SJS or TEN?
If any skin rash or mucosal symptoms develop after a new medication, especially along with fever or eye/lip involvement:
- Immediately stop the suspected medication
- Do not delay visiting a hospital
- Request referral to a dermatologist or a hospital with an intensive care or burn unit
Early withdrawal of the drug significantly reduces severity and improves survival rates.
How Can You Reduce the Risk?
- Always inform doctors about any past drug allergies
- Avoid self-medication or overuse of antibiotics and painkillers
- Educate patients to monitor symptoms after starting a new medicine
- Healthcare professionals should closely monitor high-risk medications
