Living with Stevens-Johnson syndrome

A very severe reaction, most often to a medicine, that makes skin blister and peel and affects the eyes and mouth.

Understanding Stevens-Johnson syndrome

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a very severe reaction that makes skin tissue die and detach.

It is most often triggered by medicines. The mucous membranes of the eyes, mouth, and genitals are also commonly affected. SJS and TEN are two ends of one spectrum, and it is called SJS when less than 10% of the body surface is involved. All forms are a medical emergency. It often starts with fever and flu-like symptoms. A red or purplish rash forms within 1 to 3 days, and then skin blisters and peels.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Fever and flu-like symptoms
  • Red or purplish rash
  • Skin blisters and painful raw areas
  • Severe eye redness (conjunctivitis)
  • Mouth sores and trouble swallowing
  • Genital pain or trouble urinating

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include eye disease specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
