How effective are topical corticosteroids for dyshidrotic eczema?

Dyshidrotic eczema causes small, deep-seated blisters and irritated skin, commonly on the palms, sides of the fingers or soles. A corticosteroid works locally to quiet the overactive inflammatory response. It may soften redness, tightness and itch while the blisters settle. Response can be limited when the diagnosis is uncertain, the skin is infected, or exposure to irritants continues. Stronger products are not automatically more suitable, particularly on thin skin or when used for longer than prescribed.

Use the exact product, amount and schedule prescribed for the affected skin. Apply it to clean, dry skin, then use a fragrance-free moisturiser as directed to support the skin barrier. Avoid scratching or popping blisters, and protect your hands from detergents, solvents and prolonged wet work with suitable gloves. Do not share the medicine or apply it to a different rash without advice. If improvement is not starting within the timeframe your clinician gave you, arrange a review rather than repeatedly extending treatment.

Seek prompt medical care if the area becomes increasingly painful, hot, swollen or produces pus, or if you develop fever. Urgent assessment is appropriate for rapidly spreading redness, severe swelling, extensive skin peeling, or trouble breathing. A clinician should also reassess recurring flares, cracks that do not heal, or symptoms affecting sleep, work or walking.

Ask which strength is intended for your palms or soles, how long to use it, and whether a moisturiser should be applied before or after it. You can also ask how to recognise infection and what prevention plan may reduce future flares.
