Stevens-Johnson Syndrome: Symptoms, Causes, Treatment, and Prevention

~Introduction

Stevens-Johnson Syndrome (SJS) is a rare but serious disorder affecting the skin and mucous membranes. It is often considered a medical emergency because it can progress rapidly and cause life-threatening complications. Usually triggered by medications or infections, Stevens-Johnson Syndrome causes painful rashes, blisters, and skin peeling, resembling severe burns.

Although uncommon, understanding Stevens-Johnson Syndrome symptoms, causes, treatment, and prevention is essential because early diagnosis and prompt treatment can save lives.

This article explores everything you need to know about Stevens-Johnson Syndrome, including its warning signs, risk factors, diagnosis, treatment options, and prevention strategies.

~What Is Stevens-Johnson Syndrome?

Stevens-Johnson Syndrome (SJS) is a severe skin reaction that affects both the skin and mucous membranes, including the mouth, eyes, nose, and genitals. It is often considered part of a disease spectrum along with Toxic Epidermal Necrolysis (TEN).

• Stevens-Johnson Syndrome (SJS): Affects less than 10% of body surface area.

• SJS/TEN Overlap: Involves 10–30% of body surface area.

• Toxic Epidermal Necrolysis (TEN): Affects over 30% of the body.

In this condition, the immune system overreacts, causing skin cells to die and separate from the body.

Because of its severity, Stevens-Johnson Syndrome treatment often requires hospitalization, sometimes in intensive care or burn units.

~Stevens-Johnson Syndrome Symptoms

Recognizing Stevens-Johnson Syndrome symptoms early is critical. Symptoms often begin with flu-like signs before the rash appears.

Early Symptoms

Initial symptoms may include:

• Fever

• Fatigue

• Sore throat

• Cough

• Body aches

• Burning eyes

• Headache

These early symptoms can resemble common viral infections, making diagnosis difficult at first.

Skin Symptoms

Within days, severe skin symptoms may appear, such as:

• Painful red or purple rash

• Skin tenderness

• Blisters on skin and mucous membranes

• Peeling or shedding skin

• Raw, exposed skin

• Burning sensation

The rash often starts on the face and chest before spreading.

Mucosal Symptoms

One hallmark of Stevens-Johnson Syndrome is mucous membrane involvement:

Mouth

• Painful sores

• Difficulty swallowing

• Crusting lips

Eyes

• Redness

• Swelling

• Pain

• Light sensitivity

• Vision problems

Genitals

• Painful ulcers

• Irritation

• Difficulty urinating

Because eye involvement may lead to long-term damage, immediate medical care is essential.

~Causes of Stevens-Johnson Syndrome

Understanding Stevens-Johnson Syndrome causes helps reduce risks.

1. Medications

Drugs are one of the leading triggers of Stevens-Johnson Syndrome.

Common medications linked to SJS include:

Antibiotics

• Sulfonamides

• Penicillin

• Cephalosporins

Pain Relievers

• Ibuprofen

• Naproxen

• NSAIDs

Anti-Seizure Drugs

• Carbamazepine

• Lamotrigine

• Phenytoin

Gout Medications

• Allopurinol

HIV Medications

Some antiretroviral drugs may trigger reactions.

Drug-induced Stevens-Johnson Syndrome often occurs within the first few weeks of taking a new medication.

2. Infections

Some infections may trigger Stevens-Johnson Syndrome, especially in children.

Examples include:

• Mycoplasma pneumonia

• Herpes simplex virus

• Influenza

• Hepatitis

• HIV

• COVID-19 (rarely reported)

Infection-related SJS can occur even without medication triggers.

3. Genetic Factors

Some people have genetic markers that increase risk.

Specific genes such as:

• HLA-B*1502

• HLA-B*5801

have been associated with severe drug reactions in certain populations.

Genetic screening may be recommended before prescribing some medications.

4. Immune System Disorders

People with weakened or abnormal immune systems may have increased risk.

Risk factors include:

• Autoimmune diseases

• Cancer

• HIV/AIDS

• Organ transplantation

~Risk Factors for Stevens-Johnson Syndrome

Several factors raise the likelihood of developing Stevens-Johnson Syndrome:

Medication History

Past drug allergies or reactions increase risk.

Previous SJS Episode

If you've had Stevens-Johnson Syndrome before, recurrence risk is higher.

Family History

Genetics may play a role.

Weakened Immunity

Reduced immune defenses can increase vulnerability.

Certain Ethnic Backgrounds

Some genetic variants are more common in specific populations.

~How Stevens-Johnson Syndrome Is Diagnosed

Diagnosing Stevens-Johnson Syndrome involves medical history, physical examination, and tests.

Clinical Examination

Doctors assess:

• Skin lesions

• Blisters

• Mucosal involvement

• Extent of skin detachment

Medical History

Important questions include:
