Drugs Causing Stevens-Johnson Syndrome

SJS is a serious immune-mediated reaction in which the outer skin and moist linings can become inflamed and damaged. Early symptoms may resemble an infection: fever, tiredness, sore throat, or burning eyes. Skin pain and a spreading dusky or red rash are more concerning than mild itch alone. Blisters, peeling, and sores can then affect the lips, mouth, eyes, urinary opening, or genital area. Many ordinary drug rashes do not progress to SJS, but the difference cannot be safely decided from a photograph or a single symptom. A drug-rash explanation can provide useful background while you arrange assessment.

Arrange urgent medical care if these symptoms appear after a new medicine, a dose change, or a recently restarted medicine. Bring the packets, prescription record, and names of supplements. Do not take another dose of a suspected medicine unless the treating clinician specifically directs you. Avoid self-starting leftover steroids, antibiotics, or skin products. Treatment may require hospital-based monitoring, fluids, wound care, pain relief, and specialist attention to affected eyes or other linings; an oral corticosteroid treatment page explains one treatment category, but it should never replace an assessment.

Call emergency services for breathing difficulty, faintness, inability to drink, rapidly spreading blisters, skin peeling, severe mouth or throat pain, eye pain or vision change, or extensive genital sores. Prompt care matters because damaged skin and linings can lead to fluid loss, infection, and eye complications. Keep away from suspected medicines and do not drive yourself if you feel faint or seriously unwell.

Could this be SJS or another drug eruption? Which medicines should be recorded as suspected triggers? How should pain, mouth sores, and eye symptoms be managed while I am assessed? What should I tell future dentists, pharmacists, and clinicians before receiving a new medicine?
