• The potency of the topical corticosteroid prescribed depends on the severity of the dermatitis, the size of the area affected, the location of the dermatitis, and whether it is acute or chronic:
• For acute, severe, localized contact dermatitis on the body or limbs, prescribe a potent topical corticosteroid (e.g. betamethasone valerate 0.1%).
• For chronic or more widespread dermatitis (but < 20% body surface area), potency may need to be reduced.
• In children, start treatment with a mildly potent topical corticosteroid (e.g. hydrocortisone 1%).
• For areas of thin skin (e.g. the face or genitals) and in flexures, prescribe a mildly potent topical corticosteroid.
• For areas of thick skin (e.g. palms or soles) and lichenified dermatitis, a potent topical corticosteroid will usually be needed, as penetration of topical corticosteroids is reduced, decreasing the effectiveness.
• The eyelids should be treated only with a mildly potent topical corticosteroid for a maximum of 5 days, taking care to avoid contact of the corticosteroid with the surface of the eye.
• Prescribe a topical corticosteroid in an appropriate formulation for the person and their condition:
• Ointments are recommended in preference to creams because they provide the strongest emollient effect.
• Creams may be preferred by some people, especially when used on visible areas, such as the face and hands:
• Creams are water-based and contain preservatives that can have irritant or allergen potential.
• Other formulations may be more suitable for specific areas of skin, such as the scalp, where liquids and foams will penetrate the hair better.
