When are topical corticosteroids recommended for dyshidrotic eczema?

Dyshidrotic eczema usually affects the palms, fingers or soles with small, deep-seated blisters that can itch or burn. As the blisters dry, the skin may peel, crack and become sore. A topical corticosteroid reduces inflammation during this active phase. It does not prevent every future flare, and a similar-looking rash can instead be caused by infection, allergy or another skin condition.

Apply the prescribed product in a thin layer to the affected skin, then use an emollient to support the skin barrier as directed. Keep hands and feet cool and dry, use protective gloves for wet work, and choose gentle fragrance-free cleansers. Do not pop blisters. If cracks are painful, limit friction and tell your clinician if work, walking or sleep is being affected.

Arrange review if the eruption is not improving, keeps returning, spreads beyond the hands or feet, or interferes with daily activities. Seek prompt care for increasing warmth, pus, crusting, severe pain, fever or rapidly worsening swelling, which can suggest infection. Sudden widespread blistering or mouth or eye involvement needs urgent assessment.

Ask how to distinguish eczema from fungal infection, which areas need treatment, and whether allergy testing or treatment for sweating could help. Confirm the plan for moisturising between flares and what to do when the next blister appears.
