What should you know about mild Stevens-Johnson syndrome in the mouth?

Stevens-Johnson syndrome is a serious reaction that can affect the skin and moist linings of the mouth, eyes, and genitals. The mouth may feel intensely sore, dry, swollen, or raw. Red patches, ulcers, blisters, crusting, or loose tissue can make swallowing and speaking uncomfortable. A medication may be involved, including a recently started medicine, but the cause needs clinical review. A mouth-only problem may have other explanations; the pattern, timing, and any skin or eye changes help a clinician assess it.

Contact urgent medical care today and mention every medicine, supplement, and recent infection. Do not restart a suspected new medicine unless a clinician specifically tells you to. Sip cool fluids if swallowing is safe, choose soft bland foods, and avoid spicy, acidic, or rough foods. Do not break blisters or use unprescribed mouth products. A clinician may review hydration, examine the mouth and skin, and decide whether hospital care or treatment such as an oral corticosteroid is appropriate.

Seek emergency help immediately for trouble breathing, inability to swallow fluids, drooling, faintness, marked weakness, rapidly spreading skin pain or peeling, eye pain or light sensitivity, or sores involving several body areas. These signs can indicate more extensive mucosal or skin involvement and dehydration risk.

Which medicine or illness could have triggered these mouth changes? Should any current medicine be stopped, and how will that be documented? What can I safely use for pain and hydration while my mouth heals? Do my eyes or skin need examination today?
