Hydrocortisone Prescription for Skin Allergy

Formulation and Strength Selection

For mild skin allergies, the typical prescription for hydrocortisone is a 1% or 2.5% cream or ointment applied twice daily for 2-3 weeks to affected areas, with appropriate potency selection based on the treatment area (lower potency for face/genitals, higher potency for body) 1, 2
Low potency formulations (hydrocortisone 1-2.5%) are recommended for face, intertriginous areas, and children 2
For body areas with thicker skin, higher potency corticosteroids may be needed for adequate response 1, 2

Apply a thin layer to affected areas twice daily (morning and evening) 3, 4
Apply after bathing when possible, as slightly damp skin may enhance absorption 2
For weeping/acute eczema, use cream formulations; for dry/chronic eczema, use ointment formulations 2

For mild skin allergies, hydrocortisone can be used for 2-3 weeks 3, 2
After initial treatment period, gradual tapering is advised rather than abrupt discontinuation to prevent rebound flares 2

Always use hydrocortisone with regular emollients (applied at different times) to enhance efficacy and reduce steroid requirements 2
For pruritus (itching), combine with oral antihistamines such as generic antihistamine 10 mg daily or generic antihistamine 10-25 mg QID 1, 5
For areas covering <10% body surface area (BSA) with mild symptoms, continue using hydrocortisone while adding oral antihistamines 5, 6

Monitor for signs of skin thinning, telangiectasia, and striae, especially with prolonged use 2
The risk of adverse effects increases with prolonged use, large application area, higher potency, occlusion, and application to areas with thinner skin 2
For moderate to severe cases (covering >10% BSA), consider referral to dermatology 1, 5

If no improvement after 2 weeks of hydrocortisone treatment, consider increasing to a higher potency corticosteroid for body areas 3, 4
If no improvement after 2 weeks of hydrocortisone treatment, consider adding oral antihistamines if not already prescribed 1, 5
For severe cases (>30% BSA), systemic corticosteroids may be required (generic corticosteroid 0.5-1 mg/kg/day) 1, 5
