Do topical corticosteroids treat irritant contact dermatitis?

Irritant contact dermatitis occurs when repeated or intense exposure to substances such as detergents, solvents, water, or friction damages the outer skin barrier. The affected skin may burn, sting, crack, scale, or itch. A corticosteroid calms the inflammatory response, but it cannot protect the skin from continued exposure. If the trigger remains, symptoms may return or treatment may appear less effective.

Identify and reduce contact with the suspected irritant where practical. Rinse exposed skin with lukewarm water, pat it dry, and apply a bland moisturiser frequently. Use protective gloves for wet or chemical work, with suitable liners if sweating worsens the rash. Follow directions for any corticosteroid, applying it to affected skin for the advised period. Avoid sharing prescribed products and do not apply them to the face or skin folds unless instructed.

Arrange a review if the rash persists after the exposure is reduced, covers a large area, or interferes with work or sleep. Seek prompt care for increasing pain, warmth, pus, yellow crusts, or rapidly spreading redness. Urgent help is needed for facial swelling, breathing difficulty, or a severe reaction after chemical exposure. Recurrent episodes may need assessment for allergic contact dermatitis or another skin condition.

Ask which exposure is most likely, how to use protective equipment without trapping sweat, and how long to continue moisturising. Ask whether patch testing is appropriate if the rash keeps returning despite avoiding obvious irritants.
